About silicone molding vacuum casting serviceFirst, you need to use CNC or 3D printing to process a set of prototypes according to the drawings, then mold the prototypes with silica gel, take out the prototypes, and then inject the composite mold material. Commonly used materials are ABS，PC，transparent acrylic，PP，TPU，etc. Vacuum casting is used for small batch protptype production.
The quantity of this kind of batch is very small compared with the open steel mold, generally a few sets, dozens of sets. If there is more, the cost will increase. The service life of the silicone mold is about 15 times. If you do more, you need to make more silicone molds.
Before mass production of general products, plastic parts will be produced in small batches in advance to test product performance and market demand. If it is a small batch production, the process is to choose the silicone molding vacuum casting. So if you need vacuum casting service for your plastic prototype, contact us for RFQ.
