This morning’s two orders are quite heartwarming to me. One is an old customer who knew that the price of SKH51 had increased significantly, but still paid without hesitation, which made me feel very warm. The recent price increase of tungsten alloy has tripled, forcing the prices of high-speed steel and powder high-speed steel to…

Mr. Mao inquired about punching 7 holes on 8mm thick 45 steel. The current SKH51 punching needle is prone to breakage after punching hundreds of holes. What tool steel should be used? Punch 7 holes on 8mm 45 steel, which is a harsh working condition where the punching hole diameter is smaller than the plate thickness…

 I just received a strange phone call this morning, saying that you need to come to me more often. Mr. Wang is a factory that makes export molds. The molds he is making are not wear-resistant and have been complained by a customer. He wants to find a tool steel with high hardness, good wear resistance,…

Today, a retired national athlete from Jiangsu Province visited and left a deep impression on me. He came by tram, charging once every 300 kilometers, which is equivalent to driving for 3 hours and resting for an hour. It’s over 2000 kilometers from northern Jiangsu to Guangdong. He is a boss who specializes in stamping…

Good news, Mr. Zhao, who bought 8503 die steel from me last year to make stretching molds, just called to give feedback. 8503 has a good effect and has stretched more than 20000 products without sticking materials. The effect is much stronger than Cr12MoV. Also, because the effect of 8503 is stronger than Cr12MoV, in another…

The premise of communication is trust, and someone who doesn’t trust you doesn’t need to communicate anymore. The same person came to ask again a year later, stamping 2.4mm thick stainless steel. Now using DC53 with a hardness of 59HRC, it is easy to crack. Sometimes it can be punched 20000 to 30000 times, and…

A netizen just asked me, what kind of tool steel should be used for large-sized hexagonal nuts made of hot forged 35CrMo material? In early March, there was just such a successful case. Many mold cases, after turning around, have come back to me. Mr. Bao is a hot forged 35CrMo hex nut that was…

There are two joys this morning, Yixi is Mr. Lu, who has been a good friend since 2020. Today, he suddenly sent a message asking to buy two pieces of 8566 die steel. After quoting the price, he made direct payment, which made me feel uneasy. Mr. Lu is stamping 1.5-thick 304 stainless steel, now…

 I went out for lunch this afternoon because there were guests.  At 10:30 in the morning, Mr. Yuan from Jiangsu came to visit. He works on rolling wheels and wants to create products that are different from his peers to compete with customers who have requirements for lifespan.  He actually makes tools, and the wire…

 I was too busy yesterday and didn’t have time to share some cases.  But successful cases, no matter how busy we are, must be recorded. This is not only for netizens, but also for ourselves, and more importantly, for future customers.  Received praise from Mr. Zhang for punching 0.4mm stainless steel fine teeth. High speed…
