Q
Excessive shrinkage rate of general-purpose polyethylene extruded products
Q
Die head pressure fluctuation of general-purpose polyethylene extruder
Q
Rough inner and outer walls of general-purpose polyethylene pipes
A
Rough pipe wall is caused by low mold temperature or poor surface condition, and needs to be solved from temperature control and mold maintenance.
Material Drying rough pipe wall die temperature mandrel temperature mold polishing sizing sleeve
Q
Haul-off speed mismatch of general-purpose polyethylene extruded products
A
Haul-off speed mismatch needs to be solved by accurately adjusting the haul-off parameters and ensuring stable haul-off.
Extrusion & Post haul-off speed speed matching haul-off slipping clamping force haul-off control
Q
Wide temperature window of general-purpose polyethylene PE raw material causing difficulty in process parameter optimization
A
PE temperature window optimization needs to be promoted from two aspects: systematic experiments and experience accumulation.
Processing Machinery temperature optimization PE grade DOE process parameters temperature database
Q
Longitudinal reversion rate of general-purpose polyethylene pipes exceeding the standard
Q
Frequent screen change/short filter screen life of general-purpose polyethylene extruder
A
Q
Unstable output/surging in general-purpose polyethylene extrusion process
A
Unstable output is caused by unstable solids conveying, and the barrel temperature and feeding system need to be optimized.
Extrusion & Post unstable output surging solids conveying hopper bridging screw speed
Q
Dimensional fluctuation of general-purpose polyethylene extruded products
A
Dimensional fluctuation is caused by unstable extrusion or haul-off, and each process parameter needs to be systematically stabilized.
Extrusion & Post dimensional fluctuation screw speed haul-off speed temperature stability uniform feeding
Q
Screw design mismatch of general-purpose polyethylene extruder
A
