What is Injection Molding? Injection molding is a popular manufacturing process that facilitates producing a large volume of high-quality, uniform and cost-effective plastic parts. During the injection molding process, a plastic or resin material is heated to its melting point and then injected into a custom mold. The part forms inside the mold and is released…
Choosing the right plastic material for your parts is very important. The material should be selected based on the intended application of the part. It must be able to withstand the various conditions the part will be in. Some applications may require a very specialized, high-performance and high-cost material. But for many, one of the…
Background information about Polyurethane as a material As mentioned, polyurethane (polycarbamates) belong to a class of compounds known as polymers. Polymers are macromolecules; they’re made from smaller and repeating units known as monomers. They often consist of a main long-chain backbone molecule with smaller attached side groups. A synthetic polymer, such as polyurethane, is created…
Normally tolerance on the plastic molding part is around 0.05-0.1mm, if the part tolerance requirement is about 0.01-0.03mm, that means this is precision plastic injection molding, to make high precision plastic injection molding parts, the first thing is making the precision injection mold, all of the mold components must have tolerance within 0.005-0.01mm, this is min…
What Is Plastic Mold/Molding Technology? Plastic mold technology is also known as plastic molding (or moulding) technology which is a process that has been around since 1872, it is the process of creating and manufacturing plastic components by injecting molten materials into a plastic mold. The process of plastic molding technology is actually quoted as a complex one. First, the…
