Polyamide casting - description of the process

Polyamide casting molds a generally additively manufactured master model in silicone. A monomer is cast into this silicone tool, mixed with filler material, additives as well as an activator and catalyst. The thermoplastic materials are polymerized, without pressure, directly in the tool within a few minutes. The discharge quantity amounts to about 15 pieces per mold. Undercuts are possible by forced demolding.


  • Good surfaces (similar to the master model)
  • Close-to-production material

  • Tough and very hard
  • Excellent mechanical and thermal properties
