Plastic Injection Molding is a kind of tool used to produce hundreds of or thousands of plastic parts. Most of our daily used plastic parts are made by plastic injection molding. Mould design and making is the most important process among the courses of injection molding. Generally speaking, the mould comprises of two main components, the injection mould and ejector mould, or named A plate and B plate.(Some complex parts would require three plate mould by adding a gate plate.) A plate is fixed on the stationary platen of the injection molding machine or press connected with... Read More

Thermoplastics are polymers, which soften (becomes pliable and plastic) and melt when heated. In the melted conditions thermoplastics may be formed by various methods (injection molding, extrusion, Thermoforming). No new cross-links form (no chemical curing) when a thermoplastic cools and harden. Thermoplastics may be reprocessed (re-melt) many times. Molecules of most of thermoplastics combine long polymer chains alternating with monomer units. Thermoplastic materials may contain filler materials in form of powder or fibers, providing improvement of specific material properties (strength, stiffness, lubricity, color etc.). Thermoplastic groups: Polyolefines: Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polypropylene (PP). Styrenics: Polysterene (PS), Acrylonitrile-Butadiene-Styrene (ABS), Styrene-Acrylonitrile (SAN), Styrene/Acrylic (S/A), Styrene-Maleic Anhydride (SMA). Vinyls: Polyvinyl Chloride (PVC), Chlorinated Polyvinyl... Read More
Many of the prospective clients we speak with have an incomplete understanding of what exactly is required to produce a product at scale. There’s a lot that goes into an injection molded prototype or final product but the big three are absolutely essential. Here’s the big picture: What is Required For Injection Molding A computer design (CAD software file) of your part. Creative Mechanisms specializes in creating novel designs from “napkin-sketch” concepts and then turning these ideas into physical prototypes. An injection mold tool designed to produce the CAD part. Mold tools vary depending on what stage in the production process you are in.... Read More
Once we have designed your initial prototype you need to think about the next step in the production process: creating a pre-production prototype. If you’re unsure as to the difference between “initial” and “pre-production” prototypes, it’s relatively simple: Initial prototypes are typically created using CNC machines and/or 3D printers. They are simpler, cheaper, and faster to produce. The most difficult part of initial prototype production is getting the design (CAD) correct. Generally speaking, initial prototypes are made from ABS plastic (something other than the final production material). Pre-production prototypes are typically created using injection mold machines. This requires the designer to use the CAD... Read More
Thermoplastic polyurethane (TPU) is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. Further, it can be processed on extrusion as well as injection, blow and compression molding equipment. It can be vacuum-formed or solution-coated and is well suited for a wide variety of fabrication methodologies. TPU can even be colored through a number of processes. But more so than any other thermoplastic elastomer, TPU can provide a considerable number of physical property combinations making it an extremely flexible material adaptable to dozens of uses. This is partly because TPU is a linear segmented... Read More
Design teams are always trying to come up with something better—better shapes and designs, better performance, better materials, and most importantly, a better cost. If there's a way to give their product an edge over the competition, the design team will do everything they can to incorporate it into their process and product. Cost, of course, is a huge factor. After all, there is only so much you can do to reduce costs when you follow Lean practices and/or consistently use the same set of materials, designs and processes. Often it's just a one-percent gain here, a one-percent reduction there.... Read More
When configuring your wheelchair, it’s important to consider, what wheels you need. The choice you make will depend on your primary use, be it indoor or outdoor, plus the terrain and the activity involved. And making the right choice can be crucial. Someone with a pain condition really doesn’t need a lot of vibration, and other users may value speed as part of their sense of independence. Here’s the information you need to choose wisely: The smoothness of the ride, speed, maneuverability, and control are all related to the wheelchair wheels, tires and casters. Choosing these components is not a straightforward task.... Read More
Most tires are constructed from some form of rubber. But, "rubber tires" usually refers to tires made entirely from solid rubber. Pneumatic tires are the typical tires we are use to having on our cars and bicycles. They have a solid rubber surface, but the inside is inflated with air. Advantages Solid rubber tires cannot go flat. They can get damaged, but it is unlikely that one incident will render a solid rubber tire inoperable, as can happen to a pneumatic tire. Pneumatic tires offer better shock absorption for a smoother ride and are much lighter than solid rubber tires.... Read More
What is Polyethylene terephthalate (PETE or PET), and What is it Used For? Polyethylene terephthalate (PETE or PET) is the most commonly used thermoplastic polymer in the world and is better known in the textile industry by the trade name “polyester.” It is a naturally transparent and semi-crystalline plastic widely used as a fiber for clothing, as an effective moisture barrier with wide applicability in bottling and packaging (known in these cases as PET or “PET resin”), and as an engineering plastic when it is combined with other materials like glass fiber or carbon nanotubes to significantly increase the material’s strength. It is... Read More
