Silicone extrusion is a continuous manufacturing process in which unvulcanized silicone rubber in the cylinder of a cooled extruder is transported via spiral conveyor to the extruder head. There it is pressed through a built-in nozzle (moulding tool). The raw material shaped by the tool geometry then runs directly into a heating zone located behind the extruder where it is vulcanized. Only then has the product reached its final shape. 

Typical extrusion products

  • profiles
  • round cords
  • tubes/hoses
  • squares (rectangular profiles and flat ribbons)
