There are many factors that affect punch life:
(1) the first is the selection of punch raw materials is reasonable, punch manufacturers use materials are fake.
(2) the heat treatment process of punch, preheating, austenitizing temperature and time is reasonable arrangement, cooling medium, tempering temperature and time proper support control, cryogenic treatment.
(3) mechanical processing, the size of the initial machining allowance, allowance is too large, grinding will produce annealing phenomenon, affect the hardness and toughness of the punch.
(4) mold design is reasonable.
5. Mold concentricity.
6 punch pressure, stamping number and speed adjustment.
Due to the fierce competition in all walks of life, price wars can be seen everywhere. The actual price war to be speechless, is some bad business price war is not so, but with different materials to pretend, with ASP23 instead of ASP60 material there are plenty of people. Use CR12MOV to pretend SKD11, and SKD11 to replace DC53. The same way there are domestic and imported materials, with is domestic material with good and bad points, production of different manufacturers, the quality is different, the price is not the same, of course, so there are a lot of customers like online price comparison, which will be cheaper to which order, although the price in your heart you think you get the right product, but you take in one's hand is not necessarily the real products you want, you want to buy the DC53 punch, may be to your hands may be SKD11 punch, a penny a points goods, I want to now, there's not a mold parts manufacturers are not highly profitable price space, By contrast, the price will not be too much different, why the manufacturers will have what kind of large price gap is conceivable. The same manual processing, the same processing equipment, why he can produce products at a lower price. Instead of saving money on materials, where would he get the price advantage? Is it advanced processing equipment, we all know that the advanced processing equipment of the mold parts manufacturer's price will not be low.
