Wax is injected into the mold to form a wax pattern and then welded together with gate cups and runners to form a tree···
The tree is coated with multiple layers of refractory slurry and sand to form a shell···
The shell will be heated to remove the wax inside···
The shell is baked with high temperature,molten metal will then be poured into the shell···
Shake the shell to make it fall off···
After being processed by a shot peening machine, the surface of the casting becomes smooth···
Metal parts will be cut off from the tree and cleaned, thus the required products are obtained···
