Yesterday when I disassembled the PVC extrusion dies, I found a lot of burned PVC inside. It is seems impossible to disassemble the die once a day. But if not disassembled it, burned stuff wouldnot come out. Could you give me some ideas how to clean it without disassembling it and if disassembled it which kind of tooling I should use (not damage the lip and flow channel)?
After extruding the PVC, if I put the PP in the extruder, will that help (not need clean the die)? One more question, the operator left the soft PVC material in the barrel for days without empty it. Next time when they want to use it, just heat it up. They said the flexible PVC wouldnot burn, so it was not necessary to empty the barrel. The flexible PVC will corrode the barrel and screw, will it?
