Vacuum Casting is using two-component polyurethanes which are poured in to silicone molds to make high quality rapid prototypes or end use products.

How it works:

Make Master Pattern (CNC or 3D Print) > Immersed Master into Silicon to form a mold> Removed Master and create a empty cavity silicon mold > pour liquid polyurethanes into mold and placed it into vacuum chamber > open mold and obtain identical copy

Feature and advantage:

1. Cost-effective: Lower than 1/10 of traditional injection tooling cost

2. Fast: Depends on the complexity. Lead time can be less than 2 days.

3. Low volume production or prototype: each mold can copy parts up to 25 pcs.

4. Precision: 0.3% (0.3mm within 100mm dimension)

5. Versatility:  semi material to most standard thermoforming resin, plastic, rubber, PU.

Application:

Design verification

Pre-Launch production testing

Prototype or Display

Low Volume or limited quality End use product
