Injection moulding (injection molding in the USA) is a manufacturing process for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials, including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.n the field of injection moulding, troubleshooting is often performed by examining defective parts for specific defects and addressing these defects with the design of the mould or the characteristics of the process itself.
Injection moulding consists of the high pressure injection of the raw material into a mould which shapes the polymer into the desired shape. : 14 Moulds can be of a single cavity or multiple cavities.
