We are sheet extruder and we generate about 10% waste through edge trim and floor sweeps and purgings. we do recover about 5% by grinding the edge trims and putting back in the blends. But it still adds grinding time, reprocessing costs and machine hr cost. I want to know how some have overcome...
We are a sheet extruder, we generate lot of static when rolling up the sheet in the unwinder bar. Is there an inexpensive way to reduce or eliminate static. I have looked at anti static bars, is there any other in-house method? We use copper gauze wire but not much success.
Thanks
