Navy Funds Study of Underwater Glue Made Using Protein Extracted From Mussels

Anyone who has ever made the mistake of wearing a Band-Aid in the shower knows all too well that adhesives which appear to be secure when dry quickly peel off when they get wet.The challenge of creating glue that works underwater is the focus of Bruce Lee, an assistant professor of biomedical engineering at Michigan Technological University. To help him crack this conundrum, Lee has just been awarded three years of funding from the Office of Naval Research as part of its Young Investigator Program award.Lee's work is based on looking at one of the strongest natural undersea adhesives we know of -- namely, that used by mussels to adhere themselves to rocks and the underside of boats."Mussels use a protein adhesive in order to attach to surfaces," Lee tells Digital Trends. "It's almost like injection molding: they inject it as a liquid, and then it adheres to a surface. One of those main proteins is an amino acid called DOPA. What we've done is to take that molecule and used chemistry to incorporate it into a synthetic adhesive."Lee says that there are two main possible applications for his work. The first of these would be useful for naval work involving the attaching of underwater sensors or devices on ships, submarines, or underwater robots. The second is a medical application involving the creation of dressings that will stay attached when a person sweats or otherwise gets wet.As if underwater glue wasn't enough of a challenge, Lee also wants to create an adhesive that can be switched "on" and "off" -- meaning that it could be made sticky or non-sticky at will. Doing this means figuring out how to temporarily block the DOPA molecule, thereby triggering a structural change in the adhesive."By making our adhesive reversible, the hope is that we'll be able to attach something underwater by turning it on, and then if you want to detach it, you simply turn it off again," he says. "That's something that's quite novel, and is what makes the project exciting."The Office of Naval Research funding will help Lee study the biochemistry involved with the concept. "Once we have worked out the basic mechanism, then we can focus on establishing the materials to turn this into a physical application," he saidSo, smart underwater adhesives by 2020, then? We'll stick around to find out.

Once it comes to shining in the manufacturing business, you have to be capable to keep up with all of the existing trends. At the time it comes to standards, like localism as well as doing work with companies in your own wood's neck, you should carefully understand that the game's rules are changing. Here we are discussing about the new worldwide economy that is regularly changing the way manufacturing is executed. In the earlier times, it will have been less costly to work with some types of companies in your own nation or also in your own area, but now you can see technology has completely changed this old type of conventional understanding. You can check these types of changes nowhere more obviously than in the plastic Injection molding China industry. Now, with the passing time, you can check mold companies are growing their operations to contain nations all over the world.In case you are not familiar with the possible changes in the industry of plastic injection molding, it could be just because you are not familiar with the needs of the specific industry. At start, you need to think about all of the functions that you will expect from the top-class mold providing companies. They are predictable to do injection molding, injection tooling, finishing as well as assembly. Most of the companies can just not have enough money to have an in-house procedure. It would demand enough amount of real estate with some different type of facilities. From a merely economic point of view, it is not a feasible choice in current's economic landscape.In its place, Custom Plastic Molding is a more than few step procedure which reaches all across the world. Like you can see that, mold service provider can begin with injection tooling. They could then outsource their all or just some work to facilities in China for the process of molding as well as accessories. The procedure could come to a close with meeting happening in India or Mexico. As you find, this is a business which spans the world, making a worldwide market place where the greatest bids wind, in spite of location. At the time you want to have done work of Injection Molded Parts, you need to carefully confirm that you are looking at just mold service providers that know this new worldwide model. This will indicate that you are getting a fast turnaround as well as best cost effectiveness. Once it comes to the requirements of a competitive business, it is accurately what you need to expect. You would even find that these worldwide companies have not any possible problems dealing with your personal global development.

Tips to Buy Plastic Injection Molding Machine
Injection Molding Machine uses a manufacturing process called injection molding. The specialty of such a machine is the production of parts in large scales and volumes. They are mainly used in the mass production and you can use such machines for your repetitive plastic products production. Such injection molding machines are very cost effective and you can easily complete your projects with these machines with less downtime. The costs are paid one-time initially when setting up the business and these electric molding machines are very effective for medical parts. Plastic injection molding machine is highly significant and hence you need to consider few basic things before you buy such machines. Here you can find a proper guideline to buy plastic injection molding machine. Some Tips to buy the right plastic injection molding machine At times you wish to purchase an injection molding machine for a certain job. You need to get the best machine which gives additional capacities, right configuration and size. Machine purchase is not a very easy, job and hence getting solicitation and quotes from multiple dealers is recommended. A little bit of knowledge and preparation can help you with the right purchase. a) Size of the shot- This plastic amount is rated in terms of ounce or GPPS or general purpose polystyrene for US based machineries and a cm3 for any Asian or European inject molding machines. The size of the shots of injection plastic molding machines is very important and you need to choose the best inject molding machine with proper shot cavity. So when you are searching for such a machine the best recommended practice is to go for a plastic molding machine which can produce 30 to 40% higher size of shots. b) Tonnage- Tonnage refers to clamping related pressure and it is known as clamp tonnage. Tonnage in relation to press brakes mean the number of tons of down force the machine needs to directs it to make the work piece. In terms of plastic injection molding equipment, tonnage is calculated by the number of tones which such machines can competently press the platens together. These platens are needed for holding the mold cavity and create the plastic which is injected inside the cavity in order to produce the part. c) Size of the platen- The platen here in inject molding machine is the tool or the table which helps holding the mold cavity efficiently. The entire structure is spaced out where the mold is inserted. They are clamped in a secure manner with the platens. Both the platens are joined and are held with tons of pressure. This heats the plastic and under this high pressure the plastic is injected. Then you need to cool down the plastic molds and use them for further modification. Hence the size of the platnematters to add adequate pressure for giving the part the right shapes. d) Space of the tie bar- Plastic product making machine comprises of tie bars and these bars are placed horizontally. Spacing is an important consideration and the spacing given to the platen the size of molds can be placed for the molding cycle to begin. In this regard, you can take help from the experts and manufacturers can help you to assemble such molding machines. e) Stroke of the ejector- The stroke of the ejector in a plastic injection molding machine acts or ejects the machine in a push style for the final part to be created from the platens with the help of the ejector pins. The machine will cease to work without the ejector stroke and hence you must check the strokes of the injectors before you buy a machine. Ejector located in this molding machine helps push it opposite to the plate of the ejector. Rods or pins attach them with the late and the pushing gesture is created over the molded segment after the injected plastic is hard. f) Financial considerations- When purchasing plastic injection molding machine you must understand your financial considerations. You must prepare yourself since it is a large investment. You can ask for the quote from different manufacturers and then compare their prices to choose an affordable plastic injection molding machine. You must understand the break-even point of the investment being made and developed a conservative margin mindset when making such calculations. g) Design considerations- It is also important to understand the various design considerations when making a purchase for injection molding equipment. First of all, you must recognize the part design which will be designed with the machine. Having a simple geometrical specification and minimized number of parts at an initial level will help pay the dividends effectively when moving along. You must ensure that the machine is able to design the tool of the mold and have no defects. Research about the mold defects and ensure that the machine being purchased can fix it efficiently. If not it can lead to more financial loss in the future. h) Considerations of production- The consideration of the minimal cycle time must be known first. There are machines which are based on hot runner styled technology for example which are highly efficient. Making small plans in the purchase of the plastic injection molding equipment can make a large difference in time and cost. The design of the part must be planned in such a manner that it requires minimum amount of assembly. The costs incurred to assemble the parts can be costly and hence this aspect must be reduced as much as it is possible. Hence you can significant reduce labor costs and process costs if the machine being purchased does major works by itself. You can take help from any acquaintance of yours who is in this business to have a better and in-depth knowledge about such machineries. You can also search such machines online and gather some relevant information about these molding machines. No doubt it is a huge investment and hence do not leave any stones unturned to gain knowledge about them before procuring them.1. i have a very simple invention that needs to be massed produced. I need to know how to find a company ,?We are an Chinese plastic injection factory. We can make plastic injection molding by ourselves and have our own plastic injection machine. Send me more informations about your invention, we will give you suggestions and very competitive prices. com Skype:casey84926.2. Tips for Including Lettering on Plastic Injection Molded PartsIt is common to see lettering or logos on plastic injection molded parts. They may be added to the design for a number of reasons, including to: None Provide patent or other legal or regulatory information Lettering and logos are easy to incorporate into a mold, and doing so eliminates the time and expense of secondary steps like applying labels. When designing a part that will include lettering and/or a logo, you will need to decide whether these features should be recessed (i.e. sunken) or standoff (i.e. raised). Each style has its advantages and disadvantages. For example, depending on how a part is used, raised lettering would not hold up over time in a heavily abrasive application. On the other hand, a part with recessed features can gather dirt and debris. Your decision on whether letters and logos are recessed or standoff will affect the mold as well. It is more common for features to be engraved into a mold, which results in them being raised on the part. When executed this way, the mold can be polished, which delivers a better surface finish on the completed parts. Molds with engraved features also last longer, as the features are not subject to wear. Tips for Designing Molds with Lettering and Logos Lettering and logos can have interruptions in the flow of material, which may cause imperfections like flow marks, tear drops, and streaks on the finished part. To avoid these kinds of problems, keep three tips in mind: None Avoid sharp corners in your lettering. All corners should have a radius so that air does not become trapped in the mold causing defects. None Be sure to draft your features. The sidewalls of all letters and logos should have a draft angle to ensure that the mold fills properly. None Limit the height or depth of features to 0.010". This should be sufficient to keep them from wearing away over the lifetime of the part. Greater height or depth may unnecessarily add to the cost of the part. If you have an engraved part that is used in a variety of finished products, your tooling could be created with separate, interchangeable engraving blocks. Your molder could swap out the engraving block based upon your configuration. Keep in mind that even the smallest border, commonly called a witness line, will show in your finished part around the engraving block perimeter. To address this, many designers make the engraving look deliberate by recessing the entire block very slightly into the plastic. Whether it's letters, logos, or some other feature of a mold, knowing how it will affect both your finished part and your budget is key to executing a project effectively. The advice we are happy to share with you is backed by more than 20 years of experience. Give us a call if we can be of service.3.

The Process and Benefits Associated with Plastic Injection ...
The injection molding process is used to produce parts out of plastic materials. This is an exceptional industrialized system and makes use of molten plastic to formulate packaging spouts from plastic materials. In this system melted plastic is injected in a mold of inverse design at high pressure to produce a new part in desired shape and size. In this method different molded pieces are manufactured from thermosetting plastics. The plastic injection and molding has attained a great reputation not in the world of plastics but also other fields such as consumer products, automotives, medical, plumbing and construction industries. This method is not only used in production of small parts but it is also used in manufacturing whole body of some equipments. There are various kinds of plastic molding like as injection moldings, compression moldings, film insert and blow moldings used in the industries. Apart from this thermoforming, structural foam moldings and rotational moldings are used in the industries.The production of plastic injection molded parts India is also done on large scale as it has a huge demand in the Indian market. Apart from this medical injection and molding has also become a major industry because of huge demand for medical equipments. In this procedure plastic capsules first are heated and then melted down into cylinder. After this they are forced in molds so that they get the shape of medical equipments. In this focused procedure the plastic capsules are heated and melted down in a cylinder and forced into the molds to figure the medical equipments. Medical appliances such as heart pump part, orthopedic device, oxygen parts and such equipments are manufactured using such injection technology. Really plastics are versatile because of which they are used in each and every industries present today as per their requirements.Following are the benefits associated of plastic injection and molding:Low labor costs Ability to utilize various materials High rates of production per hour Minimal losses of scrap Repeatable high toleranceMany people think that injection molding is a very complex process but it is not the fact. In fact it is a very simple process.Following is the process of injection molding: A) First resin is put in the molding unit by making use of hopper.B) Next the colorants are then fed in the machine.C) Next the resin is fed in a barrel preheated at specified required temperate to attain desired outcome.D) Next based on requirements of the manufacturing, the melted resin is injecting in the mold. After this melted resin is cooled which then solidifies in mold.E) And in the final step desired product or part is obtained. If you want to buy any of the injection molded products then you easily can search for them on the internet. You will find many sourcing manufacturers and partners providing quality products and that too at economical prices. You will find many reputed companies established themselves in this industry since a long time so you can trust themfor optimum quality molded products.
What Are the Benefits of Using Plastic Injection Molding?
Plastic injection molding is one of the most efficient methods for producing complex plastic parts at high volume. It is not only extremely efficient, but also very flexible in use with the option to make changes to the base material throughout the production process. Let's take a look at a few of the most pleasing qualities of using plastic injection molding:High accuracy Plastic injection molding is a manufacturing method that is highly accurate provided a precise mold is used. On average, the accuracy level is likely to be in the region of about 0.006 inches.Fast and efficient The fast and efficient nature of this type of manufacturing makes it the most popular option for producing a high volume of plastic items. However, the actual time to create each piece will vary with the complexity of the actual mold. A typical time to create each item is in the region of 15 to 25 seconds.Keeps labor costs to a minimum The automated nature of plastic injection molding helps to cut labor costs because this type of machinery only needs a minimal workforce to keep going. Once the actual mold is created, the machinery will keep running successfully with appropriate supervision in place.Minimize waste The ability to minimize waste and benefit the environment is certain to be an appealing quality for many. This type of machine is not only very efficient, but is also appreciated for the very small amount of waste produced at the time of production. It only needs to use the set amount needed to create each molded piece. Additionally, if there is any waste, this can easily be recycled elsewhere on a different project.Easy to change production Plastic injection molding is designed to offer great flexibility with the option to make changes throughout the production process. Several of the things that can actually be changed include the type and color of material used.High-strength parts The parts produced using this production method can easily vary in strength. A simple way to improve on the all-round strength of a part is to add a special type of filler to the base plastic material. This has the benefit of reducing the volume of liquid plastic which results in great strength and durability of the finished item. The ability to control the plastic strength makes plastic injection molding a great option for any industry that needs the super strong products.
Evaluation of Mechanical Properties and Flame Resistance of Biobased Polymer Compounds.
Biobased polymers have been introduced for some applications ofelectrical, electric, and office appliances to reduce both petroleumresource exhaustion and C[O.sub. emissions. (1) Although polylacticacid (PLA), as one typical biobased polymer, is commercially availableat present, it is necessary to improve its thermal resistance and impactstrength, as its fracture mode is brittle, and the crystallization speedof PLA is very low. (2) A PLA and PC alloy is now commercialized with aPLA content of 30 wt% or less for parts in electrical, electric, andoffice appliances, as a substitute of existing PC and acrylonitrilebutadiene styrene (ABS) alloy petroleum-based polymers in Japan. It is also important for electrical, electric, and officeappliances to maintain fire resistance. As fire resistance is requiredfor plastic materials and parts in electrical household appliances andgas appliances, advanced flame retardants, free of halogenatedretardants, have been developed. (3,4) Test Materials and Methods Materials A compound of PLA and polyamide-11 (PA11) was firstly considered toincrease the botanical percentage of organic elements in the biobasedpolymer alloy. The standard injection grade Terramac TE-2000 PLA(produced by UNITIKA Ltd.) and the injection grade Rilsan[R] BMN PA11(produced by Arkema Co.) were used in this study. The non-halogenphosphoric acid polyester grade PX200 (produced by Daihachi ChemicalIndustry Co.) and ammonium polyphoshate grade AP422 (produced byClariant K.K. (Japan)) were used as the flame retardants. PLA, PA11, acompatibilizer, and a flame retardant were mixed at various compoundingratios and extruded to form pellets. The test specimens were produced bythe injection molding. A reactive compatibilizer was selected to have an affinity to bothPLA and PA11. According to the contents of the compatibilizer, thelarger in quantity the compatibilizer was, up to 25 phr [parts perhundred resin], the greater the mechanical properties were in thepreliminary test. The 25 phr compatibilizer was selected in this study.As a reference, the PLA and PC alloy grade Ecodear[R] V554X51,commercialized with PLA content of 30 wt% or less (produced by TorayIndustries Inc.), was also selected. Compound ratios of the biobasedpolymer, compatibilizer, and flame retardant are shown in Table 1. Test methods The tensile tests specified in JIS K7161 were conducted by theInstron type 55R4206 universal testing machine at the tensile speed of20 mm/min and at 23[degrees]C. The tensile elastic modulus andelongation at breakage were calculated from the stress-strain curves.The Izod impact tests specified in JIS K7110 were conducted by theinstrumented Toyo Seiki Seisaku-sho DB-IB machine at 23[degrees]C. Thespecimen length was 80 mm, the width was 3 mm, and the thickness was 10mm. A 2-mm-deep V-notch was made to the specimen. The thermal analysisspecified in JlS K7121 was conducted with the PerkinEImer Pyris1 DSCdifferential scanning calorimeter (DSC). The melting temperature, degreeof crystallinity, and heat quantity per unit weight of the compoundswere measured. The flammability test was also conducted with the Toyo SeikiSeisaku-sho MCM-2 multi-cone calorimeter to obtain the relation betweenthe heat release rate or the integrated heat release value andcombustion time. (5) The flame-retarding effect level of the compoundswas evaluated according to the UL-94 method. Test Results and Discussion Mechanical properties After injection molding, the specimens were exposed to hot air toaccelerate crystallization at 90[degrees]C, for 3 hours, as the thermaltreatment. Figure 1 shows a comparison of the tensile modulus, the tensilestrength, and the elongation at breakage among various compounds ofbiobased polymer, compatibilizer, and flame retardant. Figure 2 shows acomparison of the Izod impact strength among various compounds ofbiobased polymer, compatibilizer, and flame retardant. Compared with the PLA/PA11 with a compatibilizer and the PLA/PA11without a compatibilizer, the mechanical properties such as theelongation at breakage after the tensile test and the Izod impactstrength were significantly improved by using a compatibilizer, althoughthe tensile modulus and the tensile strength slightly decreased. (6,7)It was also found that the Izod impact strength of the PLA/PA11 with acompatibilizer after the thermal treatment greatly increased, althoughthe elongation at breakage of the PLA/PA11 with a compatibilizer beforethe thermal treatment was high. The larger the content of flame retardant PX200 was, the smallerthe mechanical properties such as the tensile modulus, the tensilestrength, the elongation at breakage, and the Izod impact strength were,gradually. The reason is that the dispersion of flame retardant into thePLA/PA11/compatibilizer was not sufficient. Compared with the Toray Industries PLA and PC alloy grade EcodearV554X51 (mixed flame retardant with PLA content of 30 wt% or less),which is partly commercialized for a casing material and exterior partsof electrical, electric, and office appliances, the mechanicalproperties of the PLA/PA11/compatibilizer containing flame retardant wasquite equivalent to those of Ecodear V554X51, although the tensilemodulus and the tensile strength of the PLA/PA11/compatibilizercontaining flame retardant were slightly low. Morphology observation Figure 3 shows photographs indicating the dispersion of PA11 andPX200 flame retardant in the PLA region with a scanning electronmicroscope (SEM). In the case without a compatibilizer, there were manyrelatively large-size PA11 grains in the PLA region. PLA and PA11 weremiscible in the case of PLA/PA11/compatibilizer: 100/50/25, as therewere meanwhile small particles of PA11 dispersed in the PLA region. ThePLA and PA11 compound of biobased polymer will be useful as substitutionfor ABS/PC or PLA/PC. Fire resistance is required for casing materialsand exterior parts of electrical, electric, and office appliances. In the case of the PLA/PA11/compatibilizer containing the flameretardant PX200, there were agglomerated particles of PX200 in the PLAand PA11 region as the content of PX200 increased. It was found thatthere were not uniformly dispersed particles of AP422 in the PLA andPA11 regions. Thermal analysis Thermal analysis was conducted with a DSC. The scanning wasperformed for a temperature range of 50 through 200[degrees]C under anitrogen atmosphere. The heating and cooling rates were set at 50 and25[degrees]C/min. Figure 4 shows the heat quantity per unit weight ofPLA/PA11 without a compatibilizer (sample (2) from Table 1), PLA/PA11with a compatibilizer, and PLA/PA11/compatibilizer containing the flameretardant PX200 (6). Figure 5 shows the melting peak temperature ofPLA/PA11 without a compatibilizer (2), PLA/PA11 with a compatibilizer(3), and PUVPA11/compatibilizer containing the flame retardant PX200(6). It was found that the total heat quantity per unit weight ofPLA/PA11 with a compatibilizer decreased resulting in the reaction ofPLA/PA11 and a compatibilizer. However, the effect of the reaction wasreduced in the case of the PLA/PA11/compatibilizer containing flameretardant. Although the melting peak temperature increased more or lessfor PLA/PA11 with a compatibilizer compared with PLA/PA11 without acompatibilizer, the melting peak temperature deceased forPLA/PA11/compatibilizer containing flame retardant. Flammability test results Figure 6 shows the relation between the heat release rate or theintegrated heat release value and the combustion time with respect tovarious compounds. The thickness of the sample was 2 mm, the same as forthe UL-94 specified by JIS Z2391. The curves between the heat releaserate or the integrated heat release value and the combustion time forPLA:100 and PLA/PA11/compatibilizer:100/50/25 were quite different. The curves between the heat release rate or the integrated heatrelease value and the combustion time forPLA/PA11/compatibilizer:100/50/25,PLAIPA11/compatibilizer/PX200:100/50/25/50, andPLA/PA11/compatibilizer/PX200: 100/50/25/100 were similar even if theflame retardant of PX200 was blended to PLA/PA11/compatibilizer. Although the PLA and PC alloy grade Ecodear V554X51 is defined ashaving the V-0 level standardized by the UL-94 method, thePLA/PA11/compatibilizer containing 100 phr of PX200 will be defined asstill having the V-2 level due to incomplete dispersed and agglomeratedparticles of PX200 in the PLA and PA11 region. On the other hand, PLA/PA11/compatibilizer containing 50 phr ormore of AP422 had a good fire resistance satisfied to the V-0 level dueto complete dispersion of AP422 in the PLA and PA11 region. Themechanical properties of compounded materials of PLA and PC, such asEcodear V554X51, are indicated to improve the impact resistance and thethermal resistance of PLA. The PLA/PA11/compatibilizer containing 50 phrof AP422 will be a substitution of Ecodear V554X51, having heatresistance and impact resistance. Conclusions The mechanical properties and the flame resistance of biobasedpolymer compounds of PLA/PA11/compatibilizer containing flame retardantwere evaluated. Flammability tests with the multi-cone calorimeter wereuseful to obtain the relation between the heat release rate or theintegrated heat release value and the combustion time. ThePLA/PA11/compatibilizer containing the flame retardant AP422 will beapplicable for the substitution of compounded materials of PLA and PC,such as Ecodear V554X51. The compatibilizer and fire-resistancetechnology was also applied for high-performance polymer alloys. (8,9) References (1.) T. Yanagisawa et al.: Kobunshi Ronbunshu, Vol. 66, No.2, 49(2009). (2.) M.

Digital Is Changing the Economics of Manufacturing
Digital manufacturing is rapidly changing the fundamentals of how products are developed, scaled and manufactured. By digitizing traditional manufacturing methods, including injection molding and CNC machining, and leveraging newer technologies, like 3-D printing, the industrial internet of things (IIoT) and artificial intelligence (AI), companies are optimizing their supply chains, reducing development cycles, increasing efficiencies, and driving down costs. The Fourth Industrial Revolution continues to gain traction and is completely changing the economics of manufacturing, for those willing to embrace the change that is.It Makes Mass Customization Financially ViableEmpowered by connectivity and social networks, consumers are demanding more personalization than ever before. A Deloitte report noted half of consumers are interested in customized products and would be willing to pay more and wait longer if they could have an active role in design.The move from mass production to mass customization has historically had high cost implications, but the balance is beginning to tilt. Digitization now offers opportunities for manufacturers to engage in automated customization in ways they could have never imagined. Flexible models, analytics, automation, and adaptive supply chains are opening new doors to personalized manufacturing.Before they write it off as cost-prohibitive, manufacturers must consider the opportunities through a total cost of ownership approach. For example, while supply chain leaders have mainly focused on reducing the costs of components, each one of those components has its own inherent costs associated with tooling, front-end engineering and quality control. Digital manufacturing automates much of the front-end engineering associated with producing custom parts. Interactive design for manufacturability (DFM) tools offer an immediate analysis of part designs before they are manufactured, significantly reducing design risks (and potential rework costs) before production even begins. Digital manufacturing models also improve traceability throughout the manufacturing process via a digital thread that moves from 3-D CAD model to connected production floor to digital inspections and tracked shipping of final parts.Combining these capabilities can significantly reduce tooling costs for specialty parts and low-volume production runs. It's changing the economics of customization and enabling manufacturers to tap new revenue streams that were previously unattainable. Now that the traditional barriers are falling, manufacturers can seek a competitive advantage by responding to consumer demands with more iterative development, shorter development cycles and more frequent innovation.Digital manufacturing is also enabling manufacturers to bring products to market sooner, and do it in lower, limited runs much more economically than before. For example, medical startup Invoy Technologies was launching a brand-new weight-loss device to market, and with minimal demand predictability, did not want to commit to mass production right out of the gate. Instead, Invoy turned to digitally-enabled, low-volume injection molding, a cost-effective way to mitigate risk and bring brand new products to market sooner.It's Changing the Economics of Product Design and ManufacturingDigital manufacturing is enabled by multiple manufacturing methods, but one area that has really grown has been industrial 3-D printing. Over the past decade, additive manufacturing technologies have really grown from hobbyist applications to industrial-grade equipment capable of producing engineering-grade, end-use components.Many major OEMs have come to the table and are helping move additive beyond prototyping to actual production. GE has been rapidly expanding its additive manufacturing business with new applications for the oil and gas, medical, automotive and aerospace industries. HP is also using its own technology in its supply chain to reduce costs and boost speed to market for its Multi Jet Fusion printers. And last year, the FAA gave Boeing approval to use 3-D printed titanium parts in the construction of its 787 Dreamliner.Additive manufacturing not only enables the creation of new products but is also influencing design. For example, if an engineer had complete design freedom for a heat exchanger, how might he or she design it to accomplish the cooling step and reduce overall costs for the manufactured product? Redesigning the interior channels to cool the air more effectively might enable them to make a smaller exchanger and reduce process and material costs. They might also look to 3-D printing to consolidate and reduce the number of components and individual processes involved in their creation. Therefore, the real benefit of additive is really in the design freedom and assembly reduction, which unlocks tremendous opportunities in designing what previously was just un-manufacturable.It's Reducing Maintenance Costs and DowntimeManufacturers know the uptime of their equipment is critical, but many continue to use a reactive run-to-failure approach. It not only creates unnecessary risk but leaves money on the table. A study by Infosys found while more than 80 percent of manufacturers realize machine learning can enhance maintenance, less than 20 percent have instituted any productive maintenance capabilities. In fact, many manufacturers are still relying on manual analysis and using outdated systems on Excel spreadsheets.With today's capabilities, there's no reason to rely solely on time or use-based schedules and human-controlled checklists. Inexpensive, connected sensors can collect data, run it through complex algorithms and uncover trends and concerns unidentifiable to humans. This enables them to more accurately predict when a component of their manufacturing process will fail.It can be difficult for some to break from old ways, but planned and anticipated maintenance activities are far more efficient than reactive maintenance due to unplanned problems. Capital investments in software as a service (SaaS) solutions and sensors are minimal when factoring in the reduction in production downtime.The technology and opportunities are already here. Digital manufacturing can bring new opportunities, new markets, and new levels of efficiency and cost reduction never thought possible. But, one first has to be willing to adopt the new way of thinking that digital manufacturing requires.
What Is the Closing Force (locking Force) of the Injection Molding Machine?
The locking force, also known as the closing force, refers to the maximum clamping force exerted by the closing device of the injection machine on the mold. When the melt fills the mold cavity, the force produced by the injection pressure in the mold cavity always tries to make the mold open along the parting surface. Therefore, the locking force of the injection machine must be greater than the melt pressure in the mold cavity and the projection area of the plastic products and the pouring and pouring systems on the parting surface Product. Formula: the clamping force is greater than or equal to the pressure of the die * the sum of the projection area of the product, runner and gate on the parting surface. It should be noted that the clamping force is insufficient, the product is flying or cannot be formed, and if the clamping force is large, it will cause waste of system resources, and make the components of hydraulic system work under high pressure for a long time, which may aging prematurely, and the mechanical structure will wear too fast.• Related QuestionsWhere can we find a button injection molding machine?The exact question is >"Where can we find a button injection molding machine?"and the very best place to find a button injection molding machineis in a plastic button manufacturing factory.You may also find plastic injection molding machines at injection molding machinemanufacturing factories and or agents / dealers and then you will need to have button dies or molds made.If you intend to start a plastic button injection molding business you will need to learn how to run the machine/s and ancillary equipment learn plastic technology or employ people who have the knowledge you will need premises, capital and a means of distributing your buttons.

All the cutting processes that are to be carried out and all the final dimensions are fed into the computer via the program. The computer thus knows what exactly is to be done and carries out all the cutting processes. CNC machine works like the Robot, which has to be fed with the program and it follows all your instructions.Injection moulding: Material granules for the part is fed via a hopper into a heated barrel, melted using heater bands and the frictional action of a reciprocating screw barrel. The plastic is then injection through a nozzle into a mould cavity where it cools and hardens to the configuration of the cavity. The mould tool is mounted on a moveable platen - when the part has solidified, the platen opens and the part is ejected out using ejector pins.After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mouldmaker (or toolmaker) from metal, usually either steel or aluminum, and precision-machined to form the features of the desired part..Thank you..!------What are the precautions for the installation of injection molding machines?Small and medium-sized injection molding machines, because of the small vibration, can be installed without using a separate foundation, that is, the injection molding machine is placed on the horn that has been placed beforehand, and then corrected by the level to make it level.Large injection molding machines should have independent foundations. Since the clamping device and injection device of large injection molding machines are mostly separated, when installing, generally, the clamping device is installed first, and then the injection device is installed. When installing a large injection molding machine, first insert the bolt into the foot hole, place the horn and wedge iron and pour it into the concrete. After the concrete has solidified, correct the level and tighten the foot nut. Pay attention to make the fuselage joint surface fully contact for stability. When the fuselage is stabilized, various piping components between the injection device and the clamping device can be installed.The hydraulic pipelines and electrical circuits of the injection molding machine are more complicated, and it is necessary to carefully check and construct the drawings. Install the injection molding machine hopper, automatic feeding device, mechanical arm and other devices according to the pattern to make it a whole------What is the difference between a compression molded cap and an injection cap?Compression molded cap without gateMolding mode: The thermoplastic product produced by the molding process is extruded by an extruder. After a continuous working cycle, it is cut into weight-balanced plastic pellets, placed in a mold, driven by a hydraulic system, and molded by a mold. productBarrel temperature: the plastic is heated in a melted state and has a certain viscosity. The temperature is generally controlled below 200 °C.Shrinkage: Less internal orientation, less shrinkage and shrinkage of plastic parts, uniform performanceConnecting bridge: the connecting bridge is not compression molded, but is completed through the subsequent tangential processInjection molded cover with gateThe thermoplastic product produced by the injection process plasticizes the melted plastic in the barrel by the screw of the injection machine.The cavity is injected into the cavity through the pouring system of the nozzle and the mold, and the plastic is cooled and solidified in the cavity. Barrel temperature: It should ensure that the plastic is plasticized well, and the injection can be smoothly realized without causing the plastic to decompose. The temperature is generally controlled above 210 ° C, below 260 ° C------What types of materials can be molded?"There are a wide range of materials that can be injection molded, even metal and ceramic can be injection molded. However, in the medical industry, we mostly see plastic injection molding," explained Kevan. "Plastic injection molding can be broken into two categories: thermoset injection molding and thermoplastic injection molding. "Thermosets are materials that cure through a chemical reaction that is spurred by heat and pressure. Thermosets that are commonly molded in the medical industry include silicone and rubber."Thermoplastics are materials that are heated until they reach the melting temperature, and then cooled until hardened. Thermoplastics can be melted and formed over and over again, whereas thermosets cannot. Thermoplastics that are commonly molded in the medical industry include nylon, polycarbonate, polypropylene, and thermoplastic polyurethanes.""Molding the two types of plastics require different equipment, capabilities, and material knowledge," added Bryce. "It's good to know the difference between the two, when designing a product and its corresponding mold. Lately, we're beginning to see companies shift their products and components that once used thermosets to thermoplastic. Although we don't know the exact reason for this, we know that it is partially due to the natural biocompatibility and additive compounding ability of TPUs and other thermoplastic materials. "------Why do you need to set up a back pressure adjustment device for an injection molding machine?Back pressure is one of the important parameters to control the quality of melt and product in injection molding process. Proper back pressure plays an important role in improving the quality of product.In the process of plastic melting and plasticizing, the melt is constantly moving to the front of the material (measuring room), and more and more, gradually forming a pressure to push the screw backward. In order to prevent the screw from retreating too fast and ensure that the melt is evenly compacted, it is necessary to provide the screw with a reverse pressure, which is called back pressure.Back pressure, also known as plasticizing pressure, is controlled by adjusting the return throttle valve of the injection cylinder. Back pressure valves are installed at the back of the injection cylinder of the pre-plasticizing screw injection molding machine to regulate the speed of oil leakage of the injection cylinder when the screw rotates backward, so that the cylinder maintains a certain pressure. The speed (resistance) of the screw of the whole motor is called back pressure. It is controlled by AC servo valve.------How do I install a customer's big injection molding machine?Follow the installation instructions or find a technician from the sellerThe clamping height of the first measurement of injection mold, and the injection molding machine to adjust the template mold size is larger than the injection mold, and then put back the active template of the injection molding machine, the injection mold hanging up, put the condom into the positioning hole gate injection machine intermediate fixed template, and then the thickness of the mould plate injection molding machine on fine-tuning the activity template, until the counter injection mold, eat with gusto, then tighten the screws. Then, the movable template of the injection molding machine is repeatedly folded and adjusted, and the length of the stripping rod is adjusted until the material ejection distance of the injection mould reaches the requirement. Then the cooling water inlet pipe and a water outlet pipe, and then adjust the parameters of injection molding part of the plastic melting temperature, velocity, pressure, holding time, injection volume, injection speed, injection can start work. Before working, add lubricating oil to the moving parts of the injection mould. For example: guide column, guide sleeve, top rod, slide block, oblique guide pillar and other parts.------How does recycling work for household plastics? I am tired of hovering over my two bins wondering.For household plastics.. generally first its sorted..primarily to get the impurities (metal and paper) out. Then chipped into small pieces and sorted again ... (sometimes plastics are sorted by seeing if pieces will float in a certain density fluid because different types of plastics have different densities) ... all it all it goes through several washing stages.. and many times its bundled after sorting and sent to a different facility for more complete processing. Eventually the small pieces are shipped to a plastics facility where it is either used directly as feedstock for plastic injection molding or goes into a feedstock stream to be sold for plastic injection molding.> Ideally all plastics should be recyclable.. but the fact is not all plastics are recyclable economically. For instance Styrofoam. . its light and bulky and thus transportation costs tend to make Styrofoam recycling uneconomical. Same with flimsy plastic bags..they are hard to sort and light so uneconomical to recycle. Dirty plastics have their own difficulties. . thus the washing stages. . every step costs $$. Thus local municipalities have different standards about what plastics they want to accept in their recycle stream.How does recycling work for household plastics?

5 Reasons Why Opting for Injection Moulded Plastic Products Is a Good Idea
One of the most significant features of plastic as an element is its malleability - its ability to be easily moulded into the desired shape. It is for this reason that plastic is the most preferred material for manufacturing an array of products, for mundane use as well as in factories and industries. And one of the most popular means of moulding plastic into the desired shapes and dimensions is through plastic injection molding. This process essentially involves injecting molten plastic into moulds to attain the finished product in the required shape and size. So, how does plastic injection moulding aid in manufacturing plastic equipment, and why is it a good idea to opt for injection moulded products? Here are 5 reasons for the same:1. Efficient and Hassle-Free Manufacturing ProcessOne of the most important advantages of plastic injection moulding is that the process is extremely quick and efficient, requiring minimal manual intervention. With a bare minimal interval of 15-20 seconds between the different manufacture cycles, this technique significantly increases workplace productivity at factories and is also very cost-effective and user-friendly.2. More Quantity, Superior Quality & Lesser Time TakenAs a result of this ease of manufacturing, it is possible for workers to manufacture more quantity of plastic products of remarkably superior quality, but in much lesser manufacture time as compared to other processes. For this reason, plastic injection molding can substantially increase production rates and escalate sales turnover.3. Easy Manufacture of Complex Shapes and StructuresOwing to the ubiquity of plastic across different industries and for various purposes, industries are often required to design plastic products of complex natures, consisting of many nuances. Injection moulding is the go-to manufacturing process to design extremely complex patterns and shapes with astounding precision. The only prerequisite to manufacturing complex plastic products via injection moulding is that the designs of these products should be planned accurately and reflected in the moulds into which the molten plastic is to be injected. With a sound backing of good design and the right mould, injection molded pallets, crates and other plastic products can be manufactured with absolute precision, regardless of the complexity of their shapes and structures.4. Uniform Manufacture of Multiple Identical Plastic ProductsManufacturing is not only about creating products of different shapes and sizes. It is also about manufacturing identical products - such as plastic storage bins, crates, pallets etc. - in a bulk and with the same precision. This task is often not cakewalk for manufacturers, as it involves very exacting manual labour. However, with the advent of injection moulding, this obstacle may be easily overcome. The injection moulds ensure that multiple plastic products of identical shapes, sizes and structures may be easily manufactured without any errors.5. Automated Manufacturing ProcessLast but not least, the process of manufacturing plastic products by means of plastic injection molding is an automated one. A reduction in manual intervention while manufacturing these products ensures that workers and employees at factories can invest their time and efforts in more productive tasks, such as coming up with novel manufacturing solutions. This indirectly benefits customers who can avail of better quality services from plastic manufacturers.ConclusionInjection molded pallets, crates and other products are being manufactured and sold since quite some time now and are becoming increasingly popular among customers. Owing to the ease of manufacture and superior quality of such products, they are highly suitable to different industries and purposes. At Nilkamal, we strive to ensure that our injection molded plastic products are of extremely superior quality and affordable rates.
