PC Product Flaking (Delamination)

PC delamination is checked from both ends of 'shear and contamination': gate shear is the process inducement, contamination is the material inducement; delamination is an interface problem, find the root cause first before talking about the process.

PC and ABS Material Change Cross-Contamination

PC/ABS material change 'cross-contamination' is prevented by SOP: gradient temperature cleaning + disassembling and cleaning dead corners are standard actions; frequent cross material changes are the enemy of quality, use a dedicated line if possible.

PC Product Melt Fracture Marks

PC melt fracture marks = 'shear exceeding the limit': for extrusion lower temperature of the melt and raise die temperature, for '2079851475616104452 reduce speed and enlarge the gate; PC has high viscosity and high shear sensitivity, and speed management must leave margin.

PC Extruded Sheet Uneven Thickness

PC sheet thickness relies on the three-in-one stability of 'die lip + temperature control + haul-off': optical sheets need thickness closed-loop; use the thickness curve to locate the problematic die lip section for transverse deviation and adjust it targetedly.
