Cooling system: Optimized design of circulating water to improve production efficiency and reduce your costs Intermediate treatment: tempering to increase hardness. Post-processing: Nitriding (low nitriding temperature, small deformation, no need for quenching, it has high surface hardness (greater than HV850) and wear resistance) Mold life: P20 normal use is not less than 500,000 mold times Transportation method: Before the mold is shipped, the clamping piece must be installed, the packaging is firm, rust-proof, logistics transportation After-sales service: mold warranty for 1 year, free maintenance during the warranty period
