Compression Molding

Custom-Designed Products.

 

The Alternative to Metal
Compression-molded parts offer a strong, lightweight alternative to die-cast, stamped or other formed metal parts due to their superior:

  • Corrosion Resistance
  • Chemical Resistance
  • Heat Resistance
  • Fire Retardation
  • Weight Profile
  • Weather Resistance
  • Colorfastness
  • Strength
  • Microwave Transparency
