Also known as "lost-wax casting". According to the product requirements of the customer, molds are designed and processed. The wax material is pressed into the mold to form a product wax mold, which is bonded with the sprue cup and runner wax molds to form a wax tree. After coating the surface of the wax tree with multiple layers of refractory slurry and sand material, a shell is made. The wax material in the shell is melted out by heating, and then the molten metal is poured into the shell that has been fired at high temperature. After the molten metal solidifies and cools, Through post-processing methods such as cutting and cleaning, the required castings are finally obtained. Compared with other casting processes: It is applicable to a wide range of materials, and the products cast have complex structures, high surface roughness, and high dimensional accuracy. It requires little or no processing and is an advanced near-net-shape process.
