VACUUM CASTING
PROCESS
MASTER PATTERN
Masters are 3D printed models of your CAD design. Usually SLA technology is used to produce parts of ABS material. Once verified and approved, the next step is making the mold.
MOLD MAKING
Once the master is placed, liquid silicone is poured and cured at a suitable temperature. Once dried, the mold is cut open, the master is removed and ready for vacuum casting.
PART MAKING
Casting resin is poured in the empty cavity, in order to produce parts with high accuracy and finish.
VACUUM CASTING
PROCESS
Vacuum casting process uses a 3D printed SLA master pattern and silicone molds to produce high-quality, short-run parts without expensive and time-consuming hard tooling. Karkhana.io offers a wide range of Vacuum casting services using a variety of materials. We just require the .STEP file of your parts in order to provide DFM and speedy quote.
