Investment casting process always classified in 2 types, one we called is an American style Silica Sol casting process with green wax (median-temperature wax) and better sands, it makes casting parts with smooth surface, tight tolerance, normally it’s suitable for small part making and widely used in stainless steel material, also carbon steel and alloy steel etc.

Silica sol casting process is worked in a special designed workshop, with strict material, Temp. & processes controlling, it offers the best quality castings in surface finishing, tolerance and in purity of alloy grade, it is also the most expensive of all casting processes. Stainless steel investment castings ( widely used material: ASTM 304SS and ASTM 316SS ) are primarily used for corrosion resistance, abrasion resistance and they typically do not require any plating and additional machining operations, this allows the customers to have very little waste of raw material and reducing overall costs
