Q
Difficult Demolding in PU '2079851475616104452
A
Demolding difficulty is caused by adhesion and insufficient mold design; increasing draft angle is the fundamental measure
Injection Molding PU injectiondemolding difficultydraft angleadhesionejection design
Q
Periodic EVOH Surface Ripples
A
Ripples are caused by unstable injection; equipment overhaul and PID control are key
Injection Molding EVOHsurface rippleinjection stabilityequipment overhaulPID control
Q
EVOH Surface Tiger Stripes
A
Tiger stripes are caused by unstable injection front; multi-stage injection and high mold temperature are key
Injection Molding EVOHtiger stripeinjection speedmulti-stage injectionmold temperature control
Q
Obvious EVOH Surface Color Difference
A
Color difference is caused by uneven dispersion and orientation; masterbatch method and stable processing are key
Injection Molding EVOHcolor differencecolor masterbatch dispersionpigment orientationtemperature stability
Q
EVOH Surface Orange Peel
A
Orange peel is caused by rapid cooling and solidification; increasing mold temperature and holding pressure are key
Injection Molding EVOHorange peelmold temperatureholding pressuresurface solidification
Q
Severe Internal Stress Concentration in EVOH
A
Internal stress is caused by fast injection and uneven cooling; speed reduction, uniform cooling and annealing are key
Injection Molding EVOHinternal stressorientation stressannealinguniform cooling
Q
Unstable Weight of EVOH Injection Molded Products
A
Product weight stability depends on shot volume precision and holding consistency
Injection Molding EVOH injectionweight fluctuationshot volumeholding consistencyV/P switchover
Q
EVOH '2079851475616104452 Cold Slug Marks
A
Cold slug marks are caused by solidified residual material in the nozzle; increasing nozzle temperature and cold slug well design are key
