PESU Runner System
Problem Phenomenon
PESU runner size and balance, high-viscosity filling efficiency.
Cause Analysis
PESU high-viscosity runner design; short and thick principle; balanced layout; pressure loss; material saving.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Short and thick runner design; ②balanced layout; ③pressure optimization; ④material efficiency; ⑤verification and adjustment.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PESU runner is the foundation of filling; short, thick and balanced is the principle; optimization ensures efficiency and quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
