Induction Bottom pouring Vacuum Casting Machine for Gold & Silver

A vacuum casting machine uses a vacuum to suck the molten metal into the mold. A force is needed to overcome the surface tension of the molten metal. Otherwise, the metal would form into a blob and just sit there.Using the vacuum casting process to make the product is more economical. This is because the process uses silicon to make the molds. Silicone is affordable as compared to aluminum or steel and makes great final products. Moreover, the material allows you to make more products from the mold.
