Q
Pressure resistance test failure of low density polyethylene pipes
Q
Film blocking/poor anti-blocking of low density polyethylene film
Q
Insufficient equipment maintenance during low density polyethylene low density polyethylene processing
A
Equipment maintenance is the foundation of stable production; a standardized periodic maintenance system and recording system needs to be established.
Molds & Tooling equipment maintenancepreventive maintenancescrew clearancemold maintenancesensor calibration
Q
Uneven thickness of low density polyethylene blown film
A
Uneven film thickness is caused by uneven die gap, temperature, or cooling; it needs to be solved from mold accuracy and process stability.

Q
Large current fluctuation of low density polyethylene extruder
A
Q
Poor plasticization caused by screw wear of low density polyethylene extruder
A
Screw wear causes decreased plasticizing efficiency; it needs to be solved by selecting wear-resistant materials and regular maintenance.
