Thermoplastic plastic injection molding involves heating thermoplastic material, injecting it into a tool, and forming repeatable components as the material cools. The process can support straight molding as well as more specialized methods, including insert, composite, two-shot, overmolding, and reel-to-reel continuous strip molding. Tooling, material selection, part design, and quality requirements all influence the final production approach.
