Vacuum casting is an ideal choice for small batch of 
rapid prototype with a low-cost but reliable method for making a small amount of high quality prototypes. It is a casting process for elastomers using a vacuum to pour the liquid material into the

mold. This is special process by silicone

molding.We need to create a master of plastic first. Then we could use the master to duplicate the product with limited quantity.
Advantage Of 
Vacuum Casting
1)Shorter delivery time than CNC 
milling of small consumer products,prototype can be ready in a few days once the plastic master model has been created.
2) Good for testing complex structural rapid products.
3)Color can be customized by casting to meet your color requirements,for instance,rubber,
ABS material.
4) Low cost for low volume production before 
injection molding of mass production.
5)More reasonable price compared with CNC 
machining and 
3D printing for some parts.
6)We provide overmolding service, so that different types of plastic can be molded together into a single unit
