Process Flow Diagram Of Reaction Injection Moulding. Stage 1 injection followed by stage 2 holding pressure and plasticating and finally stage 3 ejection of the moulded part. The reaction occurs in the mold resulting in a polyurethane part.
Stage 1- INJECTION OF THE PLASTIC MELTS INTO THE MOULD. Injection Injection molding British English. But reaction signals a big difference.

The reaction occurs in the mold resulting in a polyurethane part. Injection molding is a manufacturing process for producing parts by injecting molten material into a mould or moldInjection moulding can be performed with a host of materials mainly including metals for which the process is called die-casting glasses elastomers confections and most commonly thermoplastic and thermosetting polymers. But reaction signals a big difference. Processing can be broken down into several unit operations.
