Large pressure loss in PCTG '2079851475616104452
Fenómeno del problema
Large melt pressure decay in the runner causes insufficient cavity pressure.
Análisis de la causa
Runner too long or too thin with large resistance, small gate size, melt temperature too low with high viscosity.
Solución
Shorten the runner and increase cross-section; enlarge the gate; increase melt temperature.
Conclusión clave
PCTG pressure loss is related to runner and gate design.
