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.

The process cycle for injection molding is very short, typically between 2 seconds and 2 minutes, and consists of the following four stages: 1  Clamping-Prior to the injection of the material into the mold, the two halves of the mold must first be securely closed by the clamping unit.eturn to top.
