PPSU runner system
Fenómeno del problema
PPSU runner size and balance; high-viscosity filling efficiency.
Análisis de la causa
PPSU 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
Solución
①Runner short and thick design; ②balanced layout; ③pressure optimization; ④material efficiency; ⑤verification adjustment.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PPSU runner is the filling foundation; 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
