Injection Molded Plastics Manufacturers

Injection molding is one of the most common processes used to produce plastic parts. It is a cyclic process of rapid mold filling followed by cooling and ejection. The material, which is generally available as grains or powders, is plasticized in an injection unit and injected into a clamped mould under high pressure. The main advantage of injection molding is that it is an economical method of mass production. Ready parts with tight tolerances can be produced in one step, often completely automatically. Thermoplastics such as nylon, polycarbonate, polypropylene and polystyrene are injection molded.
