Seeing the seven pieces of SKH51 high-speed steel and DC53 hard steel ordered by a new customer in the workshop, and recalling the conversations I had with two customers yesterday and today, I’ve become increasingly convinced that what mold steel users want isn’t just a low price, but high-quality, reliable mold steel with consistent performance.  The…

 A long-established Hong Kong-owned factory has placed another order with Yuhui for 17 pieces of 8566 anti-cracking steel.  I used to visit this Hong Kong-owned factory to solicit business when I was working for another company, but their tool steel supplier were all top global brands like ASSAB and Datong Special Steel. The company I worked…

When selecting stamping die steel, many people worry that the steel’s hardness is too low and its wear resistance insufficient. Even though the primary cause of die failure is chipping, they still worry that low-hardness die steel lacks sufficient wear resistance. This is worrying about wear resistance when they shouldn’t be, while neglecting the toughness they…

 A remark from a long-time customer made me realize that only by conducting business with integrity and a positive mindset can we earn our customers’ trust and secure their orders.  Today, a long-time customer came to purchase my 8566 anti-cracking steel. He told me that the 8566 his friend bought elsewhere was subpar—the price was…

 What type of die steel is used for hot-forged nuts? Hot-forging die manufacturers all use Yuhui 8566 die steel. We just purchased another 10 pieces. Our client specializes in hot-forged nuts. Since nuts are standard parts produced in large quantities, they require high thermal wear resistance and heat resistance. Previously, they used tungsten carbide dies.…

By adding serrations to the bolts, the service life of 8566 die steel is 20 times that of DC53, and mold costs are reduced by 80%.  Last night, I received a message from Mr. Chen: “Hello, General Manager Wu! We verified today that 8566 steel has 20 times the service life of DC53.”  Seeing a 20-fold…

 Another great day has come to an end. Although I had a couple of inquiries from clients who couldn’t afford our products, which left me feeling a bit down for a moment, we’ve got plenty of orders. I was particularly surprised by a large order from Xiamen. When she inquired last week, the buyer didn’t…

A Douyin user commented under my video: “Hey boss, your die steel is pretty good. I bought some 8566 from you to punch 2.5mm stainless steel, and after 100,000 punches, there are still no issues.” This comment is worth its weight in gold—it specifies the material, thickness, die steel type, and service life. The only thing missing is…

 I received another order for Yuhui PM23 powdered high-speed steel from Mr. Huang this morning, which touched me a little. Mr. Huang first came to us three years ago. He was stamping 1.2mm-thick quenched and tempered 65Mn steel with a hardness of 47HRC. He had previously used PM53 and PM4 punches, both of which suffered severe…

 Mr. Cheng asked if there were any die steels he could recommend that don’t stick to the material and don’t crack. He’s currently cutting 5mm iron sheets, and using DC53 for the base plate causes sticking, resulting in burrs on the products. Coating doesn’t help either—applying a coating requires polishing the mold first, which is a…

Samuel Ullman was born in Germany and was a rabbi who emigrated to the United States to escape persecution of Jews. He was also an entrepreneur who started out selling groceries and went on to become a director of a local bank. He left behind several collections of poetry, the most famous of which is…

I opened a video platform this morning and received two pieces of news—one good and one bad. The good news was that someone complained that their molds were always breaking and asked if there was a good solution. A user commented below, saying, “@Yuhui Mold Steel—just use their steel. The quality I’ve used is excellent.”…
