Plastic Vacuum Casting

Plastic vacuum casting provides a cost-effective and efficient solution for producing small to medium batches of plastic parts with good surface finish and mechanical properties. This manufacturing technique operates by creating a silicone mold from a master pattern. Once the silicone mold is ready, liquid plastic is poured into it under vacuum conditions. The vacuum environment serves a crucial purpose—it eliminates air bubbles from the plastic, ensuring a high - quality, void - free final product. This process is ideal for projects that require a relatively small number of plastic parts with decent quality and quick delivery, without the high costs associated with large-scale production methods like injection molding.

  • Various thermoplastics materials available like ABS, PC, PMMA, TPU, etc.
  • Achieve tolerances within ±0.2 mm to ±0.5 mm depends on part geometry and size
  • Short lead times, typically 3 - 5 days for a batch of 10 - 50 parts
  • Much lower initial tooling investment compared to injection molding
  • Intricate designs and undercuts structure available
