The most fulfilling case today is the stamping of 2.5mm stainless steel, and the lifespan of 8566 die steel is 8 times that of D2.
Mr. Zhang is stamping 2.5-thick stainless steel. Originally, when using D2 die steel for the punch, it would break after 5000 punches, and the broken punch would easily carry powder and damage the product. He used a continuous die, and it was troublesome to constantly change the punch, making production impossible. There are too many punch replacements, and the cost is also high, which is very painful for Mr. Zhang.
After Mr. Zhang found me, considering that the main failure mode of his punch is cracking, and he is stamping 2.5mm thick stainless steel, which is a thick and hard material stamping, I recommended him to use 8566 anti collapse die steel.
The anti cracking performance of 8566 is four times that of high-speed steel SKH-9 and twice that of D2, with a hardness of 58-60HRC. It can solve the cracking problem that high hardness die steels such as D2, DC53, and SKH-9 cannot solve; Especially in harsh working conditions such as stainless steel stamping, sharp corner stamping, narrow edge stamping, and even stamping holes smaller than the plate thickness with a stamping ratio of less than 1:1, the cracking that cannot be solved by conventional mold steel is solved by using 8566 anti collapse die steel.
After hearing my introduction, Mr. Zhang bought 8566 anti collapse die steel for trial use. Now he is using Yuhui 8566 punch, which can punch 40000 times without collapsing. The boss estimates that it can punch 100000 times.
According to the information replied by Mr. Zhang, the lifespan of the 8566 punch has been increased from 5000 times to 40000 times, which is another 8-fold increase in lifespan.
An 8-fold increase in lifespan is equivalent to replacing the punch 8 times less and stopping the machine 8 times less, which means an additional 8 hours of stamping time for the punch press. This is a dual improvement in output value and efficiency.
The lifespan of the punch has been increased by 8 times, which is equivalent to one 8566 punch being equivalent to the original 8 D2 punches. With 8 fewer punches for wire cutting, the cost of wire cutting processing can already buy a lot of 8566, which means that 8566 is free to use. It also adds 8 hours of stamping time and reduces the need to replace 8 punches. Once again, it perfectly reflects that 8566 die steel is used for punch cracking, which is a double-edged sword in both old and new societies.
