Automotive Molding

In the automotive molding sector, condensation- and addition-curing ELASTOSIL® M silicone rubber is used, for example, as a material for molds in the process of producing tire molds and in molding and surface design for car interiors (artificial leather, etc.).

Advantages:

  • Easy to process without expensive equipment
  • Very good environmental compatibility
  • Highly accurate reproduction
  • High mechanical strength

Applications:

  • Tire mold manufacturing (copying the CAD master and/or new design studies)
  • Production of interior equipment such as steering wheels and leather fittings
