Product Description
Silica sol process with green wax (median-temperature wax) and using better shell coating sand, it offers the casting parts in very smooth surface, tight tolerance, suitable for small part and precise part making and widely use stainless steel material etc, but carbon steel is possible too. Always in working the casting part in weight less than 1kgs or 0.5kgs/PC.
General investment casting process actually called soluble glass process with white wax (low-temperature wax ) and rough sand with relative rough surface, little bigger tolerance, suitable for large part making more than casting weight from 0.5 to 100KGS especially for carbon steel, alloy steel.
