Problem Phenomenon
During PETG '2079851475616104452, the V-P switchover position or pressure is inaccurate, and product weight fluctuates.
Cause Analysis
Improper V-P switchover point setting (too early or too late), hydraulic system response delay, material batch viscosity fluctuation.
Solution
Use screw position switchover accurate to 0.1mm; optimize the switchover point at 95-98% filling; stabilize material batch quality.
Key Takeaway
PETG holding switchover accuracy determines product weight stability.
