In recent years, in addition to the continued release of various high-wear-resistant, high-wear-resistant cold mold steels, flame-hardened cold mold steels, and powder metallurgy cold mold steels, the use of pig iron as raw material overseas is a very noteworthy development trend. Ductile iron castings offer excellent ductility and wear resistance, with good process properties and surface heat treatment characteristics, and are more cost-effective than aluminum alloy cast iron.

As China's industry experiences rapid development, bending mold products are extensively used in light industry, decoration, sheet metal processing factories, hardware, metallurgical industry, shipbuilding, vehicle manufacturing, and machinery and equipment fields. Compared to CNC mold steel, higher performance and usage requirements are explicitly set forth for the steel's specifications and performance.

During the processing of CNC machine bending machine mold cavities, the travel tool quantity should be minimal, and it is not necessary to leave tool marks or require polishing capacity. Even if all surfaces of the CNC mold cavity do not have production processing tool marks, polishing is still required to remove the hard base layer and white clean layer caused by CNC blade production processing or charging/discharging processing. However, it is important to note that polishing does not prevent the surface from being scorched on CNC molds, which may reduce the strength of the CNC molds.
