Among the more commonly used is the investment casting, also known as the lost wax casting:

1)Choose appropriate casting material system (such as paraffin) made for investment; Touch on casting refractory coating and sand and refractory process, sclerosis type shell and dry;

2)Then the internal casting melt away, get the cavity;

3)Roasting shell in order to obtain enough strength, and the casting material, burning residual;

4)Casting need metal materials; After shelling solidification cooling, deoxidization, can achieve the high precision finished products.

According to the requirements of the product or heat treatment and cold working and surface treatment.
