Lost Wax Precision Casting Process
- by Silica Sol
 

 

There are two types of investment casting workshops, one type is using the water glass as the main material, another is using the silica sol.

The silica sol investment castings have better dimensions and surface quality, but just too expensive than water glass. It is normally two times of the cost of water glass.

Silica sol investment casting process uses silica sol zircon sand as the molding material, which can stand temperature up to 2000 degree. This molding material is very expensive.

Silica sol investment castings have very good surface quality, very smooth, very less surface and inside defects.

The followings are photos for the steel castings made by this process.
