Analysis and solution of common problems in blowing film (6 (injection molding products)

6. The thickness of the film is too thick

Reason 1: die clearance and extrusion volume is too large, so the film thickness is too thick;

Reason 2: The air volume of the cooling wind ring is too large, and the film cools too fast;

Cause 3: The traction speed is too slow.

solution
① Adjust the die gap;

(2) Appropriately reduce the air volume of the wind ring, so that the film is further blown, so that its thickness becomes thinner;

③ Increase the traction speed appropriately.
