What is Vacuum Casting?

Vacuum casting or Silicone molding is a popular machining solution for rapid prototyping. There are three steps to make a silicone mold.

• 1. Prototype or master model: The master model need produced before silicone molding. The normal material of prototype could be ABS. It could be manufactured by CNC or 3D printing SLA.
• 2. Start making the silicone mold: Start making the silicone mold when the prototype is finished. Cut off the silicone mold and take out the prototype after a 8-hours drying. At this time, the preparation of silicone mold is ready.
• 3. Injection: Injecting liquid material into the silicone mold, and leave the mold till the material dry out.

Available Material: ABS, PC, PP, PMMA, PVC, Rubber, and other heat-resistance materials.

Advantages and Limitations:

What is the Advantage of Vacuum Casting?

• 1. Low cost. The producing cost of vacuum casting is much lower compared with CNC machining and 3D printing.
• 2. Short production time. Vacuum casting needn’t too much time on molding, which will improve the production efficiency greatly.
• 3. Needn’t make metal mold. Needn’t cost too much time on making metal mould like plastic injection molding, which could save a lot of time for customers, and it could help customers seize market quickly.
• 4. Highly restored, and low scrap rate.
• 5. Suit for low-batch production. And short customization time.
• 6. Exquisite workmanship, no burrs.
