Q
POE extrusion feeding unstable
A
Feeding instability is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core

Q
POE film printing adhesion poor
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are key
Extrusion & Post POE filmprinting adhesioncorona treatmentspecial inksurface tension
Q
POE extrusion film thick edges and thin middle
A
U-shaped thickness is caused by die flow channel and swell difference; coat-hanger die and gap fine adjustment are key

Q
POE and color masterbatch mixing color uneven
A
Color masterbatch carrier matching and full dispersion are the key to color uniformity

Q
POE extrusion surface rough
A
Surface roughness is caused by low-temperature extrusion and die defects; raising temperature and polishing the die are core countermeasures

Q
POE extruder screw severe wear
A
Screw wear is caused by filler friction and adhesion; wear-resistant screw and temperature control are key

Q
POE injection molded product oil spots
A
Oil spots are caused by external sources of release agent and lubricant; reducing release agent and sealing mold lubrication are key

Q
POE '2079851475616104452 weld line strength low
A
Q
POE '2079851475616104452 flow length ratio insufficient
A
Insufficient flow length ratio is caused by high POE viscosity; high temperature, high pressure and large gate are key
Injection Molding POE injectionflow length ratiomelt viscosityinjection temperatureflow aid
Q
POE extrusion pipe inner wall rough
A
Pipe inner wall roughness is caused by mandrel condition and insufficient cooling; polishing mandrel and internal cooling are key
