High Quantity Production Investment Casting Solutions

Investment casting, also known as  lost wax casting, is a process of using wax mold coated by refractory layers to form a shell.  When dried and hardened,  the coated mold is heated to melt out the wax to obtain an empty shell (Dewax). Then, molten metal is poured into the baked shell. After it solidifies and cools, casting can be obtained by shaking out the shell. The benefit of investment casting is better surface finish and dimension accuracy than other types of castings. 

SAIVS produces investment casting with three types of process, Silica gel (Green Wax), Sodium silicate (Water glass or Yellow Wax), or combined type as well. The material we pour includes carbon steel, alloy steel, Stainless steel, heat-resistant steel with a weight range from 0.05 to 100 kg.
