Vacuum casting - description of the process

Vacuum casting uses a master model, which is generally created using stereolithography (SLA), to manufacture a silicone rubber mold. The resulting cavity for this tool is filled with a two-component PU resin (polyol and isocyanate) with a rising and gating system under vacuum. After the plastic cures, the created parts are demolded and prepared. The discharge quantity amounts to about 25 pieces.

Benefits of vacuum casting

  • Large selection of materials
  • Casting material matches the mass-production material
  • Extremely complex components are possible
  • High mechanical strength
