Liquid Silicone Rubber

Injection Molding

Silicones, and particularly the new generations of LSR (liquid silicone rubber), continue to conquer new application areas thanks to their excellent physical property patterns, offering great opportunity for growth. At the same time, however, they burden the processor with challenges when it comes to precision and process consistency in the injection molding process. But with a system partner who is up to the task, such as KraussMaffei, the Plug & Produce concept can be applied to this material as well.

Advantages of Liquid Silicone Rubber: 

  • Biocompatible
  • Bacterially resistant
  • Can be sterilized because it is temperature-resistant
  • Permanently elastic  
  • Free of plasticizers
  • Long service life 

Advantages of the SilcoSet technology: 

  • Safe, stable processing of low-viscosity material thanks to absolute platen parallelism
  • Exact shot weight consistency even with 256 cavities
  • Consistently high component quality and thus minimum scrap thanks to APC plus
  • Absolute transparency throughout the process thanks to digital solutions
  • Easy changeover from thermoplastic processing to silicone processing
