Rubber and Silicone extrusion is a process of continuous cure whereby the raw material is custom mixed and formulated to called-out customer specifications or a ASTM, SAE, UL, or Mil Spec standards.
Rubber or Silicone material formulations are feed continuously into the extruder and through a combination of screw rotation in the barrel of the extruder and heat, plasticizers break down the material and force it through a die shaped for the part desired.
The Rubber or Silicone extrusion then continues down the extrusion line and enters a wash and cool down phase to cool and cure the extrusion to room temperature for packaging.
