Q
Ejector whitening on EAA injection molded products
Q
Uneven color when EAA is mixed with color masterbatch
A
Carrier matching of the color masterbatch and full dispersion are the key to color uniformity
Injection Molding EAA coloring color masterbatch carrier compatibility pigment dispersion color streaks
Q
Oil spots on EAA injection molded products
A
Q
Low weld line strength in EAA '2079851475616104452
A
Q
Insufficient flow length ratio in EAA '2079851475616104452
A
Insufficient flow length ratio is caused by the high viscosity of EAA; high temperature, high pressure and large gate are the key
Injection Molding EAA injection flow length ratio melt viscosity injection temperature flow aid
Q
Severe flash in EAA '2079851475616104452
A
Flash is caused by high-pressure injection and mold gaps; reducing pressure and improving mold fitting are the key
Injection Molding EAA injection flash clamping force parting line injection pressure
Q
Warpage in EAA '2079851475616104452
A
Warpage is caused by shrinkage differences and orientation stress; uniform mold temperature and holding pressure are the key
Injection Molding EAA injection warpage shrinkage holding pressure annealing treatment
Q
Premature gate freezing in EAA '2079851475616104452
A
Premature gate freezing is caused by a small gate and low temperature; enlarging the gate and raising the temperature are the fundamental measures
Injection Molding EAA injection gate freezing holding pressure transmission gate size mold temperature
Q
Burnt marks due to poor venting in EAA injection mold
A
Q
Difficult demolding in EAA '2079851475616104452
A
Demolding difficulty is caused by adhesion and insufficient mold design; increasing the demolding draft is the fundamental measure
Injection Molding EAA injection difficult demolding demolding draft adhesion ejection design
