Compression molding is a widely used method in the processing of silicone and rubber products. First, heat the mould, and then the mould heats up; then open the mold, and put a small piece of silicone or rubber into the mould cavity; then the upper mould and lower mould are combined, and the small piece of silicone or rubber is vulcanized and formed under high temperature and pressure; finally, the demoulding and trimming can be completed. 

Compression molding is often chosen for medium hardness compounds in low volume production or in applications requiring particularly expensive materials. This process helps to minimize the amount of overflow, or flash created during the rubber molding process.

Benefits of Compression Molding

• Cost effective tooling
  
• Maximized cavity count
  
• Economical process for medium precision

Compression molding can be a cost effective solution in situations where:

• The tooling already exists
  
• The cross-section of the part is very large and requires a long cure time

Applications of compression molding range from simple o-ring drive belts to complex brake diaphragms with diameters of more than 10 inches. SUPERIOR has more than 10 sets of related equipment to manufacture silicone and rubber products, including vulcanizers, rubber mixing machines, cutting machines, air compressors, etc. SUPERIOR can also offer a variety of other molded rubber products through compression molding.
