Q

PP Extruded Sheet/Plate Uneven Thickness

A

PP sheet thickness relies on the three-in-one stability of 'die lip + melt temperature + haul-off', preferably with thickness closed-loop; for transverse deviation, first use the thickness profile to locate which die lip section has the problem, then adjust targetedly—don't randomly adjust bolts ...
