Vacuum casting is a method for making high quality prototypes or low volumes of parts formed from inexpensive silicone molds. Copies made in this way show great surface detail and fidelity to the original pattern.

 

Yes, master models are used to create silicone molds for vacuum casting and can be made from any rigid solid that can withstand heat up to 100° C. Models used for CNC machining will be 3D scanned to create a CAD/CAM program for production.And attention for the transportation of your masters.

 

The service time of the silicone mold is directly related to the complexity of the casting part. Generally, it outputs 12-15 pieces before degradation. If the structure of the part is simple, one mold might be able to cast 20 parts; while if the part requires high quality such as the clear complicated part, one mold can only make 12 or even 10 casting parts.

 

Silicion molds tend to deform after being kept for a long time, so we will keep them 30 days and then we will dispose them.
