Netizens in the live broadcast room ask, what material is better for precision cutting molds? Fine cutting Q235 material, DC53+cryogenic treatment, is that okay?
I think it’s not feasible because DC53 is simply not suitable for making precision stamping molds.
Q235 is low carbon steel, which is very soft and easy to stick to molds, while DC53 is a high carbon steel with a carbon C content of 1.0%. The segregation verification is severe, and there are many fine cracks, which are prone to adhesive wear of the adhesive material, causing the product to have a sharp edge and not achieving the effect of precision punching. Even if it is subjected to cryogenic treatment, it is meaningless. If DC53 must be used, the mold must be coated.
For precision cut Q235 material, I recommend 8566 die steel and have already referenced successful cases.
8566 is a proprietary anti collapse steel developed by Yuhui tool Steel, which mainly solves the problem of mold cracking; 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 tool steels such as D2, DC53, and SKH-9 cannot solve; Especially in harsh working conditions such as stainless steel stamping, thick plate stamping, precision stamping molds, sharp corner stamping, and narrow edge stamping, the cracking that cannot be solved by conventional tool steel is solved by using 8566 anti collapse steel.
Mr. Gui precision punched the steel back of the car brake disc, made of 6mm Q235B material. The service life of SKD11 is less than 5000 times, and imported SKH51 high-speed steel is prone to cracking, making the price extremely expensive. But with 8566 anti collapse steel, it can be cut 74401 times without breaking the mold, and the service life is increased by more than ten times. The price is also cheaper than imported SKH51.
Mr. Gui’s case is similar to the netizen’s working condition, which is also made of precision punched Q235 material and 6mm thick plate. He has tried many types of tool steel before, but the effect was not good. However, 8566 can precision cut 774001 times, and the service life has been increased by more than 10 times. The effect is very good and can be used for reference.
So, the netizen asked, what kind of tool steel is better for precision cutting molds? Fine cutting Q235 material, DC53+cryogenic treatment, is that okay?
My answer is no, precision cutting Q235 material and DC53+deep cooling are not feasible. We need to use 8566 anti collapse steel.
The use of 8566 die steel for punch cracking is a double-edged sword in both old and new societies.
