When using non-ferrous metal alloy materials for molding, non-ferrous metal alloy extrusion equipment can be used for direct extrusion molding to achieve mass production. However, the dimensional accuracy of such mass-produced products is difficult to accurately control, and they can only be used as blanks. The subsequent finishing of the blanks can only rely on CNC machining centers, resulting in high production costs for non-ferrous metal alloy parts. Especially for special-shaped non-standard parts, due to the irregular shape of the product, there are more curved surfaces and arc grooves. Relying on CNC machining, the size of the product is also difficult to meet the design requirements, resulting in a relatively high processing defect rate and cost of the product.
