Rubber Compression Molding Process Description

The rubber compression molding process begins with a piece of uncured rubber which has been performed to a controlled weight and shape. This preform is placed directly into the rubber mold cavity prior to mold closure. As the mold is closed, the material is compressed between the plates causing the compound to flow to fills the cavity. The material is held in the mold under high pressure and elevated temperature to activate the cure system in the rubber compound (rubber is vulcanized). The cycle time is established to reach an optimal level of cure. At the end of the cycle, the parts are removed or ejected from the cavities and the next cycle begins.
