Although compression moulding in a press is one of the most traditional processing methods in the advanced composites industry, it is still very popular with many companies for high-volume production. This process involves using the mechanical force exerted by an industrial press to compress the preform to the desired shape. The preform is placed on the lower part of the mould (fixed part), the upper part is then overlapped and the mould is closed. The press applies the necessary mechanical power to completely fill the mould in which the preform is contained. A vent is placed in the lower part of the mould with the task of venting excess resin. When the resin has hardened, a finished component ready for finishing will be inside the mould. Pressure moulding generates components with important mechanical values and maximum repeatability in the process.
