1506 Fragen
Q
EMA Injection Molded Product Ejector Whitening
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 Injection Molded Products Have Oil Spots
A
Q
EMA '2079851475616104452 Low Weld Line Strength
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 '2079851475616104452 Severe Flash
A
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fitting are key
Injection Molding EMA injection flash clamping force parting line injection pressure
Q
EMA '2079851475616104452 Warpage
A
Warpage is caused by shrinkage differences and orientation stress; uniform mold temperature and holding are key
Injection Molding EMA injection warpage shrinkage rate holding pressure annealing treatment
Q
EMA Injection Gate Freezes Too Early
A
Premature gate freezing is caused by small gate and low temperature; enlarging the gate and increasing temperature are fundamental measures
Injection Molding EMA injection gate freezing holding pressure transmission gate size mold temperature
Q
EMA Injection Mold Venting Burn
Q
EMA '2079851475616104452 Demolding Difficulty
A
Demolding difficulty is caused by adhesion and insufficient mold design; increasing draft angle is the fundamental measure
Injection Molding EMA injection demolding difficulty draft angle adhesion ejection design
