Silicone Rubber Manufacturing Process

Common molding methods of rubber compound
  • 01 Silicone Rubber Manufacturing Process

    Compression Molding

    A production model in which the rubber is put into a mold cavity and placed between the upper and lower plates of a flat vulcanizing machine, and pressure, temperature, and time are given under certain conditions to complete the mold after vulcanization.

  • 02 Silicone Rubber Manufacturing Process

    Extrusion Molding

    It is a method of continuously forming rubber material through a certain shape of dying under the extrusion of the extruder screw. This method is used for rubber hose, wire coating, and cable sheath.

  • 03 Silicone Rubber Manufacturing Process

    Secondary Sulfur Addition

    Secondary sulfur addition refers to post-stage vulcanization, which is generally carried out in an oven. The first purpose is to remove residual decomposition products of vulcanizing agents in products; The second is to keep the products in good thermal stability when in use.


  • Silicone Rubber Industry
