Generally, the service life of Zinc alloy die casting die is 200,000 to 300,000 mold times for alloy structural steel, and 1 million mold times for die steel. The level of overseas zinc alloy die-casting molds is basically 300,000 to 500,000 molds, and some can reach 1 million molds.

The melting point of zinc alloy is 400-430°C. Zinc alloy die casting die surface temperature is not easy to exceed 400 ℃. Due to the low operating temperature, in addition to common mold steel, alloy structural steel can also be used to manufacture molds, and even high-carbon steel can be used. After medium-temperature solid carbonitriding, heat treatment, and ultra-low temperature quenching, the application effect is also very good.
Raw materials commonly used in the production of Zinc alloy die casting die include: alloy structural steel, such as 40Cr, 30CrMnSi, 40CrMo, etc.; die steel 5CrNi.Mo, 5CrMnMo, 4Cr5MoSiV, 4Cr5M0SiV1, 3Cr2W8V, CrWMn, etc.
