Compression Molding

Compression Molding is exactly how it sounds. Think about when you were a kid punching your fists in play dough. After you moved your fist away, the impression of your fist remained; compression molding is similar to this. The process comes in a two part molding and to start the material that going to be manipulated is placed onto the mold. To get the shape, the press brings the male and female molds together while being heated. This allows it to compress the heated material into the shape and the thickness is determined by the distance between the male and female molds. Lastly, the molds are separated again and the material is formed into the shape of the compression. This process can be used to mold thermoset plastics, fiber based plastics, or ceramics. Products produced from this process is bowls, cups, switches, and other similar household products.
