People who work in surface treatment/metal coating industry, got some pieces that stick to each other and can’t be separated during the treatment in (tonneaux) so the outcome is (non-conform). Got any ideas to solve this problem?

Oh wow, that sounds like a tricky problem to solve. We’d suggest taking a step back and looking at the process from a different perspective – maybe there’s something you’ve overlooked that could help separate the pieces during treatment. Otherwise, it might be worth considering investing in some higher quality equipment to reduce the chances of these problems occurring in the future. Good luck!
