Investment Casting

Investment casting is also called "lost wax casting". A mold is made according to customer's product requirements. 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 later coated with multiple layers of refractory slurry and sand to form a shell. The shell will be heated to remove the wax inside and then baked with high temperature. Molten metal will then be poured into the shell. When the molten metal solidifies and cools down, metal parts will be cut off from the tree and cleaned, thus the required products are obtained. Compared with other casting processes, investment casting applies to a wider range of materials and more complex-structured products. After investment casting, the product will gain a high-quality surface finish and high dimensional accuracy. It almost forms the final shape and structure required, without or with very little machining.
