It often refers to a casting scheme made of precision casting materials, where several layers of refractory materials are coated on the shape surface to form a mold shell, which is then melted out to obtain a mold without a parting surface. After high-temperature calcination, it can be filled with sand and poured. Often referred to as "wax loss casting". Molds can be made of sand, metal, or even ceramics. Precision casting can maximize the similarity between blanks and parts, and the dimensional accuracy and surface roughness of products are ideal. Therefore, it can reduce machining allowances or even avoid machining, saving processing time and tool consumption. Generally speaking, replacing forgings and welds with investment casting can reduce the quantity of parts by more than 15%, reduce machining hours by more than 30%, and lower the overall manufacturing cost of parts by more than 15%. The same applies to precision casting.

For customers, it is important to meet the requirements of product quality and performance. In addition, economic analysis related to material and energy consumption, production costs, prices, service life, and reliability analysis cannot be ignored. Precision casting has its distinct characteristics in general metal forming processes, but if the product selection is appropriate and the part design is reasonable, it can demonstrate the advantages of precision casting in reducing cutting, assembly, and saving metal materials. Precision casting is an important process in the manufacturing of XCMG products. For parts with complex structures that cannot be machined and require high precision, precision casting is used. Therefore, precision casting is an important core technology of XCMG's manufacturing process, and the production of casting molds will be completed by highly skilled craftsmen.
