When I first started the production, I didn't have any foam when I was wrapping up the semi-finished product. A lot of small bubbles appear when you cut a small volume into a semi-finished product. Although there are bubbles. But the viscosity is good, but the visual doesn't feel good. I hope you can help me
Ordinary slitting machine just cut out the seal belt must have bubbles, placed for a period of time will automatically respond to disappear, there is a special machine, after cutting, there is no bubble
That's what we've done. We won't have it in a few days
When cutting, bubbles are sealed and placed for a period of time
