Practical answers to common plastic material challenges

1506 questions
Q
CEF and color masterbatch mixing color uneven
A
Carrier matching of the color masterbatch and sufficient dispersion are the key to color uniformity

Q
CEF injection molded part has oil spots
Q
CEF injection weld line strength low
Q
CEF injection flow length ratio insufficient
A
Insufficient flow length ratio is caused by the high viscosity of CEF; high temperature, high pressure and large gate are the key

Q
CEF injection flash severe
A
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fitting are the key

Q
CEF injection warpage deformation
A
Warpage is caused by shrinkage differences and orientation stress; uniform mold temperature and holding pressure are the key

Q
CEF injection gate freezing too early
A
Early gate freezing is caused by small gate and low temperature; enlarging the gate and increasing the temperature are the fundamental measures
