At the request of my viewers, I went live again.
Last night, on June 13, 2026, I streamed for 1 hour and 35 minutes. This was my 295th live stream, nearly three months after my previous one—the 294th live stream on March 20.
Once you stop doing something, it’s hard to get back into the swing of things. If it weren’t for a viewer’s reminder, I might have stayed away indefinitely. I’d like to thank that viewer for this.
This livestream reached 14,000 impressions, attracted 1,402 viewers, with an average watch time of 2.05 minutes per viewer. The average concurrent viewership was 32, and the peak was 51. These impressive metrics are a reward from my viewers.
Judging by these numbers, I should definitely do more livestreams. The data shows that there are still many people interested in mold steel and eager to learn more about it.

It’s worth noting that after not streaming for a few months, TikTok’s rules have changed a bit. Previously, live stream titles could be very long, but last night I discovered there’s now a character limit. At first, I thought my phone was malfunctioning—when I tried to type “Cr12MoV,” after typing the “C,” I couldn’t type the “r.” I even tried typing it out in WeChat first and then copying and pasting it, but it still only displayed the letter “C.” After fiddling with it a few times, I finally realized it was the character limit.
Because of this issue—which took me a few minutes to sort out—I lost the motivation to stream on two platforms at once, so I decided to stick with just TikTok. Maybe focusing on just one platform actually helps me stay more focused; this little hiccup might have been a blessing in disguise.
Last night’s livestream topic was: “Never Use Cr12MoV for Deep-Drawing Dies.”
Since using Cr12MoV for deep-drawing dies inevitably causes wire drawing—and there’s no way to fix it—I shared viewers’ experiences with this issue, along with my solutions and relevant case studies.
Judging by the feedback from viewers in the live stream, this topic resonated with quite a few people. Last night, many asked what tool steel to use for drawing dies, and I discovered that many are currently using Cr12MoV for their drawing dies—all of whom are experiencing wire-drawing issues, with poor results even after applying coatings.
Perhaps the topic struck a chord with viewers, which is why so many asked questions during the live stream about what tool steel to use for drawing dies made from various materials. They’re also struggling with sticking and stringing issues in their drawing dies, which is why this topic is still being widely discussed in the livestream.
This is a question I’m frequently asked. In my view, it’s a well-worn topic, but the fact that so many people are still facing this problem shows that there will always be unsolved issues in the mold industry.
So I think I should do more livestreams when I have time and talk more about tool steels—maybe someone out there needs this information right now. These days, when people run into problems, it’s hard to find the right person to talk to. If you have questions about die steel, feel free to reach out to me.
Last night’s livestream also brought two pieces of good news.
First, after consulting me during the livestream, someone went straight to my Yuhui Die Steel Douyin store and purchased 8566 die steel. That kind of trust is so direct—I’m really happy about it.
Second, someone in the live stream praised how well 8566 performs for cold stamping of red copper. They’d tried many other mold steels before that kept breaking, but now that they’re using 8566 chipping-resistant steel, it doesn’t break anymore. Seeing how pleased they were, they kept leaving comments in the live stream.
Every live stream brings surprises, and every live stream yields something valuable—it’s really great.
