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 is the most important plastics manufacturing process. It produces such small products as bottle tops; sink plugs, children's toys, containers, model kits, disposable razors and parts of cameras.It is also used to manufacture larger items such as dustbins, and milk crates.he process can even mould such large items as dingy hulls and kit car body shell parts. Injection moulding used to be operated by people on the factory floor but these days it is a form of highly automated form of production.
