Working in the University of Wisconsin-Stout plastics lab, we demonstrate how to set up the webline handling and haul away of a LabTech blown film extruder.
@1:00 you either had not enough air or you were pulling too hard :) Your bubble collapsed on itself. Rookie move. Next time bump the screw up to 32 so you have more product to accept the air blown within... And, no gloves once reclaiming product, unless you want to lose fingers. Rollers and gloves never mix well,
Could anyone know? If I got the stable shape of bubble, I should close the inner air of blower or still open it? (“Inner air” I mean the air for blow bubble inside.) Thank you :)
Idk about blown molding. But blown film isnt that hard to learn. There is a learning curve. I work at a global plastic company. I do this on a much larger scale. But for level 1 training. It usually last 3 months. I did my level 1 training in about 2 or 2 and a half months.
