Compression moulding offers many advantages during the production process and to the properties of its components. Compressed parts have a higher durability than parts manufactured using the injection moulding process. They do not have a visible injection gate, very low shrink, and they have a higher surface quality. It is very easy to change the material and colour. Therefore the compression moulding is ideal for small batch sizes.
In combination with pressure and temperatures of 130 to 180° C, thermosets react as a chemical process, thus generating the high forces of resistance typical for this material. Thermoset materials can be processed in the form of granulates, powders, tablets, SMC mats or BMC compounds. The production cycle time strongly depends on the handling (insertion, screwing into the thread, etc.) as well as on the curing time.
