Q
Unbalanced filling of multi-cavity in EAA '2079851475616104452
A
Unbalanced multi-cavity filling is caused by runner design; balanced runners and mold flow analysis are the key
Injection Molding EAA injection multi-cavity balance runner design gate size mold flow analysis
Q
Ejector whitening on EAA injection molded products
Q
Unstable feeding in EAA extrusion
A
Unstable feeding is caused by granule characteristics; loss-in-weight feeding and anti-bridging are the core
Extrusion & Post EAA feeding bridging loss-in-weight feeder granulation feeding screw
Q
Poor printing adhesion of EAA film
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are the key
Extrusion & Post EAA film printing adhesion corona treatment special ink surface tension
Q
EAA extruded film thick at the edges and thin in the middle
A
The U-shaped thickness is caused by the die flow channel and swell differences; coat-hanger die and gap fine-tuning are the key
Molding Process EAA film thickness distribution coat-hanger die gap fine-tuning edge effect
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
Rough surface in EAA extrusion
A
Q
Severe screw wear of EAA extruder
A
Screw wear is caused by filler friction and adhesion; wear-resistant screws and temperature control are the key
Extrusion & Post EAA extrusion screw wear nitrided screw filler friction bimetallic screw
Q
