injection machine

Injection molding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection molding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, el astomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical shaped screw), and injected into a mould cavity,
