1.Mold material: P20
P20 die steel has been pre-hardened to 285-330HB (30-36HRC), and then hardened, tempered, nitrided, and nitrided to obtain a high-hardness surface structure. The surface hardness after nitriding can reach 650-700HV ( 57-60HRC) The mold life can reach more than 1 million times.
2.Experienced mold design team, more then 25 years experience,ensure mold concept is reasonable
3.High precision imported machinery equipment such as CNC machine, guarantee mold quality
4.Supply trail mold service,cast qualitied products before delivery molds. have 6 APG clamping machines to trail molds.
