Q
Rough Surface of CMC Extrusion
A
Rough surface is caused by low-temperature extrusion and die defects; increasing temperature and polishing the die are core countermeasures

Q
Poor Printing Adhesion of CMC Film
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are the key

Q
CMC Extruded Film Thick at Edges and Thin in the Middle
A
U-shaped thickness is caused by die flow channel and swell differences; coat-hanger die and gap fine-tuning are the key

Q
Uneven Color of CMC Mixed with Color Masterbatch
A
Color masterbatch carrier matching and full dispersion are the key to color uniformity

Q
Insufficient Flow Length Ratio in CMC '2079851475616104452
A
Insufficient flow length ratio is caused by CMC high viscosity; high temperature, high pressure and large gate are the key

Q
Severe Screw Wear of CMC Extruder
A
Screw wear is caused by filler friction and adhesion; wear-resistant screw and temperature control are the key

Q
Low Weld Line Strength in CMC '2079851475616104452
Q
Material Sticking to Sizing Sleeve of CMC Extruded Pipe
A
Sizing sleeve sticking is caused by elastomer adhesion characteristics; polishing and lubricating water are the key

Q
Rough Inner Wall of CMC Extruded Pipe
A
Rough inner wall of pipe is caused by mandrel condition and insufficient cooling; polishing the mandrel and internal cooling are the key
