They come from skipped maintenance.
Most sealing machine failures aren’t caused by poor quality. They come from skipped maintenance.
Here’s a simple 10-minute routine widely used in professional workshops:
- Clean heating elements
Residue, oil, and dust cause uneven seals. - Check belt tension
Too loose leads to slipping; too tight increases wear. - Verify temperature accuracy
Temperature irregularities account for over 70% of sealing errors. - Light lubrication on moving parts
Not daily — but weekly lubrication keeps things smooth. - Clear the worktable
Small debris such as film scraps can cause unexpected jams.
Follow this routine regularly and you’ll notice something:
your machine becomes a lot less temperamental.
