<\/figure>\n\n\n\n\u00a0When Mr. Huang contacted me on March 6, 2026, the product scratches in his bending dies were primarily caused by adhesive wear failure due to material sticking. This is because the Cr12MoV and DC53 die steels currently in use suffer from severe segregation, resulting in a large number of microscopic cracks invisible to the naked eye, which leads to material sticking. This issue requires improving the smelting quality of the die steel. Based on previous feedback from customers who had used 8566 die steel for pipe forming dies\u2014which reported excellent results\u2014I recommended that he switch to 8566 die steel<\/a><\/strong>.<\/p>\n\n\n\n Three months later, Mr. Huang provided the following feedback: \u201cNow that we\u2019re using your Yuhui 8566, we\u2019ve been able to produce over 70,000 units before the die shows even slight wear. At that point, the products start to develop scratches, and we have to polish the mold to continue using it. Since 8566 die steel<\/strong> is so expensive, having to polish it after such a small number of cycles isn\u2019t cost-effective.\u201d<\/p>\n\n\n\n Seeing \u201cover 70,000 cycles,\u201d I was quite satisfied; I thought that was a very high production volume. In my experience, \u201cnot many products\u201d usually refers to 3,000 to 5,000, or 7,000 to 8,000\u2014certainly never exceeding 10,000. With over 70,000 products now, that should be considered a substantial volume.<\/p>\n\n\n\n But I didn\u2019t expect him to be completely dissatisfied. Does \u201cnot many products\u201d mean at least 100,000 in his understanding?<\/p>\n\n\n\n Sales is tough. Some people think 70,000 is a lot, while others think it\u2019s very few. There\u2019s no standard\u2014either perspective is valid.<\/p>\n\n\n\n It seems that in future consultations, I\u2019ll need to clarify exactly what \u201cnot many products\u201d means\u2014whether it refers to a few hundred, a few thousand, or tens of thousands\u2014so I can make comparisons later.<\/p>\n\n\n\n *************<\/p>\n\n\n\n
