Vacuum Casting begins by producing a master model, typically using Stereolithography or Laser Sintering, with a high-quality surface finish. Then a silicone mold is produced by casting silicone around the master copy, partially under vacuum to avoid air bubbles. After curing, the silicone mold is cut according to pre-defined parting planes and the master is removed, leaving a cavity to make copies.

Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities. Vacuum Casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts.

  • Type of casting Technology: Vacuum Casting.

  • Materials: Vacuum Casting materials can simulate the following production materials and properties like;

  • i) Rubber – high flexibility

  • ii) ABS – high rigidity and strength

  • iii) Polypropylene and HDPR – high elasticity

  • iv) Poly-amide and glass filled nylon – high rigidity

  • v) Poly-carbonate and PMMA – shock resistance, translucence, high temperature resistance

  • vi) Filled ABS – fire resistance and retardant   

                                                                                                                                                                                              

  • Dimensional Accuracy: ± 0.3% (with lower limit on ± 0.3 mm on dimensions smaller than 100 mm).

  • Minimum wall thickness: To ensure that the mold is filled properly, a wall thickness of at least 0.75 mm is necessary. For best results, we recommend a wall thickness of at least 1.5 mm.

  • Surface Structure: High-quality surface finish comparable to injection molding.

  • Common Applications: Functional parts; Complex ducting ; Low run part production.

  • Typical quantities: Up to 20 copies per mold (depending on the mold’s complexity and the casting materials).

  • Strengths: Functional parts, good mechanical properties; Complex geometries.

  • Ideal applications for Vacuum Casting: Pre-launch product testing, Small series of housings, Concept models and Complex prototypes.
