Introduction
Thermosetting compression moulding is a plastic processing technique that has found widespread application in various industries due to its unique ability to produce durable and dimensionally stable parts. This article aims to provide a detailed understanding of the thermosetting compression moulding process, its working principles, key stages, and the range of applications it serves.
What is Thermosetting Compression Moulding? Thermosetting compression moulding involves the use of heat and pressure to shape thermosetting plastics into desired forms within a preheated mould. Unlike thermoplastic materials, thermosetting plastics undergo irreversible chemical changes during heating, resulting in a solidified product that maintains its shape even after exposure to heat. Working Principles of Thermosetting Compression Moulding The process begins with the preparation of the mould, which is usually made of metal and heated to a specific temperature. The mould temperature is critical as it affects the flow and curing behavior of the plastic material. The mould is then charged with the powdered or preformed thermosetting plastic material.
