Q
MP '2079851475616104452 multi-cavity filling imbalance
A
multi-cavity filling imbalance is caused by runner design; balanced runners and mold flow analysis are key
Injection Molding MP injection multi-cavity balance runner design gate size mold flow analysis
Q
MP injection molded product ejector whitening
Q
MP mixed with color masterbatch uneven color
A
color masterbatch carrier matching and full dispersion are key to color uniformity
Injection Molding MP coloring color masterbatch carrier compatibility pigment dispersion color streaks
Q
MP extruded film thick edges thin middle
A
U-shaped thickness is caused by die flow channel and swell difference; coat-hanger die and gap fine-adjustment are key
Molding Process MP film thickness distribution coat-hanger die gap fine-adjustment edge effect
Q
MP extrusion rough surface
Q
MP extruder screw severe wear
A
screw wear is caused by filler friction and adhesion; wear-resistant screw and temperature control are key
Extrusion & Post MP extrusion screw wear nitrided screw filler friction bimetallic screw
Q
MP injection molded products have oil spots
A
Q
MP '2079851475616104452 insufficient flow length ratio
A
insufficient flow length ratio is caused by MP high viscosity; high temperature, high pressure and large gate are key
Injection Molding MP injection flow length ratio melt viscosity injection temperature flow aid
Q
MP '2079851475616104452 low weld line strength
Q
