ABOUT COMPRESSION MOLDING
Compression molding is a process Dingfeng utilizes for the manufacturing of three-dimensional molded foam and foam composite parts. It is an ideal process for making parts that have intricate features, require very defined part geometry, have varying wall thicknesses or need to be held to critical dimensional tolerances.
THE COMPRESSION MOLDING PROCESS
The foam or foam composite is heated in an industrial convection oven and then placed in a machined, matched tool which is mounted in a molding press. The mold is then closed using hydraulic pressure. This pressure forces the heated and now pliable material into contact with all of the mold surfaces while the pressure is maintained. Once the material has cooled, the mold is opened and the finished part is removed from the tool.
On most parts, we are also able to cut the perimeter and any internal features of the part during the molding process . Cutting features in tandem with the molding process results in a finished part and allows us to avoid the expense of a secondary cutting operation.
