Coulée de silices are mainly used for products with haute corrosion resistance and precision dimensions, since silica sol steel casting can have much better surface quality and less geometrical deviation of dimensions. The main silica sol steel castings we ever made include meat grinder parts, valve castings, pump castings, marine hardware, and furniture decoration etc.

Usually, Coulée de silice parts tolerance within GB/T6414, CT5~6, weight range from 20 grams to 50 kilograms, the surface finish is Ra6.3.

Fonderie de silice vs fonderie de verre d'eau

Both silica sol casting and water glass casting belong to investment casting or lost wax casting. So process of silica sol casting is almost the same as water glass casting. But silica sol investment casting process uses silica sol zircon sand as the molding material, which can stand temperature up to 2000 degree. 

The silica sol investment castings have better dimensions and surface quality, but just more expensive than water glass casting. Coût of silica sol casting is almost twice than the cost of water glass casting. Below are the main differences between solica sol casting and water glass casting.
