Q
Longitudinal Streaks on CMC Extruded Film
Q
CMC Film Blocking and Difficult Layer Separation
Q
Bending Deformation of CMC Extruded Profile
A
Profile bending is caused by uneven cooling and uneven flow velocity; homogenization and alignment are the key to solution

Q
Severe Flash in CMC '2079851475616104452
A
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fitting are the key

Q
Unstable Dimensions in CMC Extrusion
A
Extrusion dimensional stability depends on feeding accuracy, temperature control and haul-off synchronization

Q
Poor Thickness Uniformity of CMC Extruded Film
A
Film thickness uniformity needs coordinated optimization from three aspects: die design, gap adjustment and cooling

Q
Excessive Thermal Shrinkage of CMC Film
A
Film thermal shrinkage is caused by orientation freezing; reducing draw ratio and annealing treatment are the key

Q
Premature Gate Freezing in CMC '2079851475616104452
A
Premature gate freezing is caused by small gate and low temperature; enlarging the gate and increasing temperature are fundamental measures
