Lost wax casting process overview
Lost wax casting, also known as investment casting or precision casting, is a use of fusible materials (such as wax) made of fusible model, and in its surface covered with refractory materials made of casting, and finally through the heating to make the model melt out, so as to get the required metal casting casting method. This process has the advantages of high precision, high complexity, high surface quality, etc., and is capable of producing a variety of metal parts with complex shapes and fine structures.
The basic process of lost wax casting includes: wax mold making, mud wrapping, wax mold melting out, metal casting and post-processing.

First, an accurate wax mold is made using a fusible material (e.g., wax) based on the design drawings of the part.
Then, a refractory material (e.g., mud) is applied to the surface of the wax mold to form the casting.
Next, the pattern is heated until the wax mold melts, allowing the wax material to flow out and form a cavity.
Finally, molten metal is poured into the cavity and after it has cooled and solidified, the casting is removed and post-processed, such as grinding and polishing.
