Between yesterday and today, I’ve received inquiries from two customers regarding the rapid wear of cold forging dies for optical modules.  Cold forging dies for optical modules experience rapid dimensional wear and require high precision. Currently, we’re using 8407 die steel, but the dimensions wear out and exceed tolerances within two days at most, and…

Even when specified, the mold manufacturers won’t buy it. Although end users specify that mold makers should use Yuhui’s high-toughness LG mold steel, the mold makers simply won’t purchase it.  A customer just came in to complain that while Yuhui’s LG steel no longer cracks in cold heading dies for aluminum parts, its wear resistance isn’t…

I saw these 90 pieces of machined, high-toughness LG die steel blanks in the workshop, ready for shipment. I’m in a good mood, so I wanted to share this with everyone.  This customer manufactures cold-extruded, shaped, and bent aluminum products. Previously, they used Cr12MoV and SKD11, both of which were prone to sticking to aluminum shavings, resulting…

Don’t assume that just because a customer calls you five times, they’re going to place an order. They’re not calling to buy your die steel; they’re just calling to confirm whether their understanding is correct.  On May 26, Mr. Long called me and asked what kind of die steel he should use for cold extrusion of red copper to…

Mr. Lu asked, “What die steel works best for stamping phosphor bronze?” Molds for stamping phosphor bronze are prone to copper powder adhesion. I asked him to clarify: “What thickness of phosphor bronze are you stamping? What die steel are you currently using? Are you experiencing corner chipping, or is it a copper powder adhesion issue?”  He is stamping…

When handling customer complaints, don’t take a confrontational approach; instead, put yourself in their shoes and listen to their concerns.  Sometimes, what you think is not necessarily what the other person wants.  If you start with a confirmation bias—assuming that the other person’s concerns are the same as your own—then everything you do afterward will…

Mr. Chen asked which tool steel is best for hot-forged stainless steel punches. Currently, the SKH-9 steel wears down very quickly—the tip wears out after just a few dozen uses—while the M42 steel breaks at the tip after only a few uses. Hot-forging dies for stainless steel operate at high temperatures, so the die steel must have good…

As a stamping factory specializing in high-end products, I need a die steel engineer on my team—that’s the impression I got after speaking with the engineer.  Today, the tooling manager and a tooling designer from a listed company in Shenzhen visited us. They were facing issues with their cold heading dies and, having exhausted all other options,…

The 8566 anti-chipping steel has tripled punch life—this is the first positive review we’ve received today.  Mr. He was stamping 4mm-thick No. 50 steel. The product features sharp corners, and the narrow flange punch—which extends outward—is relatively long, with a width of only 4mm. Previously, he used DC53, which chipped after 10,000 stamping cycles. Now,…

I was reading a book this morning that mentioned five essential qualities needed to make a name for yourself in a large corporation:  First, an understanding of management. Large corporations don’t need geniuses or artists; in such environments, the ones who take center stage are those who can motivate others.  Second, patience. Interpersonal relationships in…

It’s the weekend, and I was a little moved when a friend from MySteel sent me a photo, so I wanted to jot this down.  “My Steel Network” is a platform. They wanted to find out who the top influencers in the steel industry are, so they asked China’s ChatGPT, “Doubao,” “Who are the top…
