Q
Oil spots on EEA injection molded products
Q
Low weld line strength in EEA injection
Q
Insufficient EEA injection flow length ratio
A
Insufficient flow length ratio is caused by EEA high viscosity; high temperature, high pressure and large gate are the key

Q
Material sticking to the sizing sleeve of EEA extruded pipe
A
Sizing sleeve sticking is caused by elastomer adhesion characteristics; polishing and lubricating water are the key

Q
Rough inner wall of EEA extruded pipe
Q
EEA extrusion film longitudinal streaks
Q
EEA film blocking, difficult delamination
Q
EEA extrusion profile bending deformation
A
Profile bending is caused by uneven cooling and uneven flow velocity; homogenization and alignment are the key to resolution
