After a full day there, I have to admit that the hot forging shop was really hot\u2014so hot that you felt like you were about to get heatstroke.<\/p>\n\n\n\n
But there were a few positive developments worth noting:<\/p>\n\n\n\n
1) The heat resistance and thermal fatigue resistance of 8433 heat-resistant steel are better than those of H13\u2014this was stated by the shop foreman himself;<\/p>\n\n\n\n
2) The mass production of 8433 die steel was a success, even though the hot forging involved 316L\u2014the most difficult grade of stainless steel to work with\u2014and the process involved hot forging heavily deformed dumbbell-shaped round bars into sheet metal, which puts significant strain on the dies.<\/p>\n\n\n\n
3) This was another case of hot forging on a hydraulic press with a very long forming cycle\u2014the holding time alone lasted as long as 2 seconds. The parts also had to be heated to 1,100 degrees, meaning the die was in prolonged contact with high-temperature components. This can easily cause the die\u2019s hardness to be annealed away, leading to die collapse. The current H13 dies cannot be used for mass production precisely because they collapse too quickly, but the 8433 held up.<\/p>\n\n\n\n 4) This on-site service visit was the first of its kind in history. It not only demonstrates our commitment to the project but also highlights my technical expertise\u2014setting me apart from competitors, particularly a certain company.<\/p>\n\n\n\n 5) During this visit, I provided extensive recommendations regarding die structure and optimization strategies, all of which were endorsed by their CEO, technical director, and shop floor supervisor.<\/p>\n\n\n\n 6) On-site service tests not only your attitude but also your technical expertise. They\u2019ve already invested over 100 million in this project, and now that the mold can\u2019t support mass production, their 300 CNC machines have no material to process. The CEO is extremely anxious\u2014if you don\u2019t present a practical solution and help him resolve the issue, they won\u2019t take you seriously.<\/p>\n\n\n\n After returning to the office, I called the CEO\u2014the second-in-command\u2014to report on the day\u2019s production status and proposed solutions. I could tell he was satisfied. He said, \u201cWe\u2019ve taken a lot of detours; we should have reached out to you sooner.\u201d<\/p>\n\n\n\n \u201cWe should have reached out to you sooner\u201d\u2014that was the most gratifying thing I heard today. It meant my hard work hadn\u2019t been in vain.<\/p>\n\n\n\n *************<\/p>\n\n\n\n![\"\"](\"https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/09\/\u52b3\u65af\u83b1\u65af\u5e7b\u5f71.jpg\")
