“Shocking Development” – Electrically Conductive Silicone is now ready for Medical Device Applications


Our focus in Silicone Injection Molding has enabled us to provide our processing enterprise across the top material types that are the best fit for the industries we serve.

  • Liquid Silicone Rubber (LSR)
  • Durometer ranging from 5 to 80 durometer
  • High Consistency Rubber (HCR)
  • Durometer ranging from 20 to 80 durometer
  • Room Temperature Vulcanizing Silicone (RTV)


Our equipment utilizes cost-effective, high-end molding technology to keep operating expenses down while producing parts with an extremely high level of precision and repeatability. Our tools are designed and manufactured to exacting tolerances. Expert toolmakers use high-tech design software and machining centers to produce molds that are durable and dimensionally repeatable from cavity-to-cavity, part-to-part! Platform tooling designs are utilized to minimize tooling cost and shorten mold delivery time, resulting in a prompt development cycle schedule.

We can find the right manufacturing solution for any project. Our wide range of state-of-the-art molding equipment features:

  • Integrated automation
  • Multi-drop, Cold Deck Technology
  • Precise injection units with proprietary technologies


  • Automated Injection Molding
