The Benefits of Various Silicone Rubber Processing Methods

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

  • High production rates; short lead times
  • Ideal for tubing rods, larger gaskets, seals, wire insulation, preforms for compression molding  

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

  • Low per-part production price 
  • Ideal for products requiring close dimensional tolerances 

Liquid Injection Molding – Liquid Silicone Rubber (LSR) injected into a closed, heated mold.

  • 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. 

  • Economical method for short runs and start-up production 
  • Ability to mold large, fairly intricate parts; ideal for gaskets, seals, O-rings 

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; can be “cured in line” to provide continuous roll of solid or sponged sheeting

3D Printing - Making three-dimensional solid objects from a digital file by laying down successive layers of liquid silicone rubber in an additive process.

  • Brings the power and versatility of silicone technology to liquid additive manufacturing
  • Enables fast prototyping and small manufacturing trials of complex parts and new design option

Coating – Use of opposing knives or squeeze rolls to apply liquid silicone rubber to fabric.

  • Opposing knives promote penetration while squeeze rolls facilitate film-forming
  • Typical applications include pipe wrap, conveyor belts, welding blankets, architectural applications and expansion joints

Moldmaking – Using two-part, RTV silicone rubber to create flexible molds of various objects for reproduction.

  • Can also be used to create prototypes, rubber pads for transfer printing and robotic skins for animated creatures
