Compression Molding

Compression Molds

Material is placed in a heated mold cavity, pressure is applied
to force material evenly into mold. Heat & pressure are
maintained until material is cured. A high-volume, high pressure method suitable for molding complex, high strength reinforced
composite plastic.

Advantages of Compression Molding

  • Ability to mold intricate parts with short cycle times.
  • Lower cost than resin transfer molding.
  • Little material waste
  • Fewer knit lines
  • High quality surface finish and texture available
  • Higher temperature resistance
  • Low volume or high volume
  • Standard and custom formulations of Bulk Molding
    Compound (BMC) and Sheet Molding Compound (SMC) available
  • Complex shapes can be molded including thick and thin sections
  • Excellent thermal and electrical insulation properties

Disadvantages of Compression Molding

  • Flashing
  • Manual molding cycle only
  • High tooling costs-steel molds
  • Restricted to one reinforcement throughout part.

Markets:

Best Value for highly loaded parts such as engine components,
pressure vessels, vehicle components, electrical enclosures,
seating , architectural doors and others.
