11636 perguntas
Q
EMA Film Poor Printing Adhesion
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are key
Extrusion & Post EMA film printing adhesion corona treatment special ink surface tension
Q
EMA 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-tuning are key
Molding Process EMA film thickness distribution coat-hanger die gap fine-tuning edge effect
Q
EMA Mixed with Color Masterbatch, Uneven Color
A
Color masterbatch carrier matching and full dispersion are the key to color uniformity
Injection Molding EMA coloring color masterbatch carrier compatibility pigment dispersion color streaks
Q
EMA Extrusion Rough Surface
A
Rough surface is caused by low-temperature extrusion and die defects; increasing temperature and polishing the die are the core countermeasures
Extrusion & Post EMA extrusion rough surface die polishing extrusion temperature melt elasticity
Q
EMA Extruder Severe Screw Wear
A
Screw wear is caused by filler friction and adhesion; wear-resistant screws and temperature control are key
Extrusion & Post EMA extrusion screw wear nitrided screw filler friction bimetallic screw
Q
EMA Injection Molded Products Have Oil Spots
A
Oil spots are caused by external sources of release agent and lubricant; reducing release agent and sealing mold lubrication are key
Injection Molding EMA injection oil spots mold release agent lubricant exudation mold sealing
Q
EMA '2079851475616104452 Low Weld Line Strength
A
Low weld line strength is caused by insufficient molecular entanglement; high-temperature high-speed injection and overflow wells are effective countermeasures
Injection Molding EMA injection weld line insufficient entanglement injection temperature overflow well
Q
EMA '2079851475616104452 Insufficient Flow Length Ratio
A
Insufficient flow length ratio is caused by EMA high viscosity; high temperature, high pressure and large gates are key
Injection Molding EMA injection flow length ratio melt viscosity injection temperature flow aid
Q
EMA Extruded Film Longitudinal Stripes
A
Longitudinal stripes are caused by die defects and pressure fluctuation; die maintenance and pressure stabilization are key
Extrusion & Post EMA film longitudinal stripes die gap melt pressure lip flatness
Q
EMA Film Blocking, Difficult Layer Separation
