How long is the service life of forging molds generally?
For low-alloy structural steel forging, the one-time service life of the forging die varies according to the complexity and precision of the shape of the forging. The die forging hammer has a die life of 4,000 to 7,000 pieces. However, the new type of program-controlled full hydraulic die forging hammer, because its energy and program can be set and controlled, the die life has been improved. The die life of screw press is slightly lower than that of mechanical press, and the die life of mechanical press can generally reach 10,000 to 25,000. The service life of connecting rod mold is 15,000 to 25,000, the life of crankshaft mold is 8,500 to 18,000, the life of steering knuckle mold is 6,000 to 14,000, and the life of gear mold is 10,000 to 35,000. . The average life of domestic mechanical press molds is 5,000 to 8,000, while friction press molds have a lower life of 2,000 to 3,500, generally only about 25,000.
