Among the more commonly used is the investment casting, also known as the lost wax casting: 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;
Then the internal casting melt away, get the cavity; Roasting shell in order to obtain enough strength, and the casting material, burning residual;
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.
