Thermosetting Compression Moulding is a plastic processing technique that holds significant importance in the manufacturing industry, especially for the production of heat-resistant and durable plastic parts. This process involves the use of thermosetting plastics, which undergo chemical crosslinking during the moulding process, resulting in a permanent, rigid structure.

    The fundamental principle of thermosetting compression moulding lies in the unique properties of thermosetting plastics. Unlike thermoplastics, which can be repeatedly softened and reshaped by heating, thermosetting plastics undergo irreversible chemical changes during the first heating cycle. Once the plastic is heated and pressed into the desired shape, it solidifies and retains its form permanently.
