Silicone Molding and Welding

Molding is the process of melting and modifying a material to incorporate it into a mold with in order to get a final product with a certain shape. In Merefsa the molding process is performed by compression and injection.

  • Injection moulding is the process by which thanks to the injection of high pressure silicone in a mould, parts are produced with a geometry previously designed and machined. In addition to this more usual process, there are several types of mold that will go depending on the characteristics of the mold. final product as co-injection, bi-injection and overmoulding.
  • Compression molding is the process composed of parts in which silicone it is deposited in an open mold and with high temperature to which pressure is subsequently exerted in order to that acquires the form of the same and with the heat vulcanize perfectly.
