There’s no future in producing counterfeit or substandard products. Customers will only be fooled once, and if you only make one-time sales, you’ll never build a successful business. That was my immediate impression after speaking with Mr. Zhao just now. Mr. Zhao purchased our Yuhui 8566 crack-resistant steel some time ago. Since he needed to…

When stamping 2.5-thick stainless steel, Yuhui’s 8566 die steel increased the mold’s service life by 8 times, which delighted Mr. Zhang. However, upon hearing that 8566 die steel was the same material as H13, Mr. Zhang was puzzled. Here’s what happened: Mr. Zhang’s mold was used to stamp 2.5mm-thick stainless steel, and the product featured some narrow…

Today I met with three clients who left a strong impression on me—two came to our office in person, and one called for a consultation. I get the sense that mold steel users like to treat themselves like guinea pigs: they buy the medicine themselves, brew it themselves, and take it themselves; if it doesn’t work, they…

After several days of deliberation, Mr. Du’s order for 8566 round bars was finally placed. This is a classic and successful case study: hot-forging No. 10 steel motor housings, hot-forged motor housings made from 10 steel, with hot-forging punches made from 8566 die steel—each punch has a total service life of over 200,000 strokes. In…

“Our hot forging dies need to be re-surfaced every half day, and each resurfacing takes three hours. The time spent on production is about the same as the time spent on repairs. Is this cost-effective?” Mr. Zhu asks: We are currently using H13 steel for hot forging dies made from 2CrMoA, 20MnCr5, and 20CrMoTiH materials,…

We received an inquiry from Mr. Huang regarding a progressive die for single-step fine blanking of 4.0-thick TM500 pickled sheet. The gear teeth are quite small, and the current punches are prone to chipping—they chip after only a few hundred pieces, making production impossible. What type of die steel should be used for this gear fine…

Question from a viewer during the 300th live stream: What type of die steel is best for punching 3mm-thick aluminum?  When punching aluminum, many die failures are caused by aluminum shavings sticking to the die, resulting in burrs on the product. However, many people mistakenly believe this is due to insufficient hardness or poor wear resistance of…

Yesterday, I was chatting with a classmate, and he asked me, “With your 8566 mold steel, all your competitors are copying you—they’re all imitating you. Doesn’t that make you angry?” I thought about it for a moment and realized that if you’re angry, you’ve only got yourself to blame. When people imitate your product, you…

 Mr. Zhou asked: We’re punching 3-millimeter holes in 3-millimeter stainless steel mesh. We can currently use SKH51, but it’s not very durable—it only lasts for about 10,000 to 20,000 punches. Since we specialize in making sieve mesh, replacing broken punches is quite a hassle.  That’s right. When punching mesh with densely packed holes, the punches…

More and more customers are buying 8503 die steel that resists material sticking.  For wok drawing dies, DC53 and Cr12MoV were previously used, but both were prone to stringing. A friend recommended that 8503 mold steel, which resists material sticking, is less likely to cause stringing in drawing dies, so this time he purchased three 8503 round rings.  The…

S136-D can be mirror-polished to 18,000 grit, but I rarely mention it. It wasn’t until a long-time customer contacted me a couple of days ago to buy S136-D mold steel that I realized it had been a long time since I’d filmed a video like this. He currently uses S136 mold steel for his mirror-polished molds, but…

For stamping 2mm stainless steel, I still recommend 8566 anti-chipping steel because it offers excellent value for money.  This afternoon, I received inquiries from two customers stamping 2.0mm stainless steel. One had chosen the wrong material—Cr12MoV is prone to chipping—while the other used the very expensive ASP23 material, but it developed burrs at the wear points…
