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.ike all industrial processes, injection moulding can produce flawed parts. In 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.
Reaction injection molding is a process of making machine parts and product components. The reaction molding process differs from normal injection molding in one important wayâthe material used in the molding process requires a curing phase while the material is still in the mold. The forming material used in a reaction injection molding process offers specific advantages over the materials used in normal molding. On the other hand, reaction injection molding requires more time and expensive forming materials. Injection molding is a common manufacturing process.
