Thermosetting compression moulding is a pivotal process in the manufacturing of durable, high-performance polymer components. This technique involves shaping thermosetting plastics, which, unlike thermoplastics, undergo a chemical change during the curing process. This chemical reaction, typically initiated by heat or pressure, creates a rigid structure that cannot be remelted or reshaped, making it ideal for producing parts that need to withstand harsh conditions and mechanical stress.

    The process begins with the placement of a pre-measured amount of thermosetting resin, often combined with fillers and additives, into a heated mould cavity. The mould, usually made of metal, is then closed, applying both heat and pressure. The heat triggers the curing reaction, where the resin chemically bonds into a hard, inflexible structure. Once cured, the part is removed from the mould and is ready for use.
