Draw on our silicone processing experience

Extrusion  – Continuously extruding uncured rubber through a die to form a desired, uniform, cross-sectional size and shape before curing

  • Per part price varies by complication of extrusion
  • Tooling cost varies by requirement requested
  • High production rates
  • Short lead times
  • Ideal for tubing rods, larger gaskets, seals, wire insulation, preforms for compression molding
  • Used with High Consistency Rubber (HCR) and Fluorosilicone Rubber (FSR)

Injection molding – Extruding unvulcanized preform rubber through a cylinder into a closed heated mold.

  • Low per-part production price
  • High production rates attainable
  • Short molding cycles possible
  • No preform preparation
  • No trimming required with correct mold design
  • Ideal for products requiring close dimensional tolerances, uniformity
  • Used with HCR and FSR

Liquid injection molding – Liquid Silicone Rubber (LSR) injected into a closed, heated mold.

  • High production rates possible
  • Automated processing
  • Ideal for intricate designs, close-tolerance parts (e.g., keypads, connector seals, baby bottle nipples, etc.)

Compression molding – Placing preform rubber into a heated mold, and then into a press to allow the silicone elastomer to melt and fill the mold cavity.

  • Low to medium production rates
  • Economical method for short runs and start-up production
  • Short setup time
  • Low waste with correct mold design
  • Ability to mold large, fairly intricate parts
  • Ideal for gaskets, seals, O-rings
  • Used with HCR and FSR

Calendering – Compressing silicone rubber in a multi-roll process to produce continuous sheeting.

  • Ideal as precursor for mandrel-wrapped hoses and ducts or to die-cut seals
  • Can be coated onto fabrics or unsupported in very low coat weights/thicknesses
  • Can be "cured in line" to provide continuous roll of solid or sponged sheeting
  • Used with HCR and FSR compounds
