Q
Glass Fibre extruded film has gel particles
A
Gel particles are caused by insufficient melting; raising temperature and mixing are key
Extrusion & Post Glass Fibre filmgel particlesmelting temperaturemixing sectionhigh molecular weight component
Q
Glass Fibre '2079851475616104452 low weld line strength
A
Low weld line strength is caused by insufficient molecular entanglement; high-temperature high-speed injection and overflow well are effective countermeasures
Injection Molding Glass Fibre injectionweld lineinsufficient entanglementinjection temperatureoverflow well
Q
Glass Fibre extruded film longitudinal streaks
A
Longitudinal streaks are caused by die defects and pressure fluctuation; die maintenance and pressure stabilization are key
Extrusion & Post Glass Fibre filmlongitudinal streaksdie gapmelt pressurelip flatness
Q
Glass Fibre extruded profile bending deformation
A
Profile bending is caused by uneven cooling and uneven flow velocity; uniformization and alignment are the solution key

Q
Glass Fibre '2079851475616104452 severe flash
A
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fit are key

Q
Glass Fibre difficult purging
A
Difficult purging is caused by Glass Fibre strong adhesion; PE flushing and temperature reduction are key

Q
Glass Fibre extruded film thick edges and thin middle
A
U-shaped thickness is caused by die flow channel and swell differences; coat-hanger die and gap fine adjustment are key

Q
Glass Fibre extrusion rough surface
A
Rough surface is caused by low-temperature extrusion and die defects; raising temperature and polishing die are core countermeasures

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