Silicone Injection Molding

Silicone Injection Molding – Processing of an Outstanding Polymer

What can you expect from RAUMEDIC as a silicone injection molding expert?

Drawing on our silicone experts' many years of experience, we shape our customers' ideas into customized system solutions. The cornerstones are an optimal material selection and high-precision tools. Our production environment, which is specially equipped for the requirements of silicone injection molding, permits highly automated production using multi-cavity molds with short cycle times and very low scrap rates. The entire value-added process occurs as per GMP guidelines under clean room conditions according to ISO class 7.

  • U-connectors and connectors directly molded on silicone tubing – produced under clean room conditions


  • Decades of silicone material expertise, both in extrusion and in molding
  • Support for our customers, starting from the idea through product- and process development up to industrial manufacturing
  • Customized prototype production, small-scale production and fully automated large-scale production


  • Liquid silicone rubber (LSR) and high-consistency silicone rubber (HCR) processing
  • 2K injection molding, both silicone/silicone and silicone/thermoplastics
  • Insert molding and overmolding of extruded silicone tubing with silicone molded parts
  • Precision molded parts starting with a weight per piece of 0.008 g and very narrow tolerances
  • Thin-walled and highly elastic molded parts with minimum wall thicknesses < 0.20 mm and minimum hardnesses of 10 Shore A


  • Further finishing and assembly of your silicone molded parts into system components
  • Customer-specific qualification and validation of the tools and processes
  • Measurements and tests in our own laboratory
  • Certification according to ISO 13485
  • Certification according to primary packaging standard DIN EN ISO 15378

What advantages does silicone offer you?


Excellent chemical and physical properties

  • Outstanding resistance to high temperatures up to approx. +250°C
  • Outstanding resistance to low temperatures down to approx. −40°C without loss of elasticity
  • Very good ageing resistance

Excellent sealing function

  • Low compression set
  • High permanent elasticity

Great design freedom with regard to industrial production

  • Variations in wall thickness without negative visual impact
  • Undercuts can be reproduced through forced ejection from mold

High biocompatibility

  • Suitable for contact with blood
  • Very well tolerated by the skin
  • Excellent extractables profile (smallest amounts of extractables substances)
  • All common sterilization processes are possible
