Rubber Compression Molding Process

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.

Advantages of Rubber Compression Molding

  • Tooling can be less complex and lower cost to construct
  • Lower percentage material runner scrape vs. traditional injection or transfer molding
  • Process is suitable from most elastomers and cure systems

Disadvantages of Compression Molding vs. other rubber molding methods

  • Labor for preforming material can add cost
  • Cycle times may be longer
