Thermoplastic Injection Molding Process

A principal process for manufacturing custom plastic parts or components, thermoplastic injection molding involves taking thermoplastic material in the form of pellets or grannuals and heating the material until a melt is obtained. The melt is then forced into a split-die chamber/mold where it cools to form the desired shape. The mold is opened, the part is ejected, and the cycle is repeated.
