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

From Design to Production
Vacuum casting begins with master model preparation, followed by silicone mold creation, polyurethane resin pouring, and vacuum degassing. After curing, parts undergo demolding and finishing for final production-ready components.
Design Phase
Create 3D model for part, select materials, optimize design.
Machining Setup
Program CNC code, set up machines for work
Pattern & Mold
Make master pattern, create silicone mold
Resin Casting
Pouring resin in mold, vacuum to remove bubbles
Curing & Demolding
After resin cured, carefully demold part
Finishing Touches
Trim excess, finish surface for final look
