ermosetting compression moulding: an insight into the process and its applications

Introduction

In the world of plastic manufacturing, thermosetting compression moulding stands as a reliable and versatile process for fabricating high-performance plastic parts. Distinguished from thermoplastic moulding, this technique involves the use of thermosetting plastics, which undergo irreversible chemical crosslinking upon heating, resulting in dimensional stability and excellent mechanical properties.

The Process of Thermosetting Compression Moulding Thermosetting compression moulding begins with the careful preparation of the mould. The mould, usually made of metal, is designed to withstand the high temperatures and pressures required for the moulding process. It is also crucial to ensure that the mould’s design accurately reflects the desired shape and dimensions of the final product. The next step involves loading the mould with the thermosetting plastic material. This material, often in the form of powder or prepregs (pre-impregnated fibres with resin), is carefully packed into the mould cavity. Prepregs offer the advantage of uniform resin distribution, ensuring consistent part quality.
