MP internal shrinkage cavity
Fenómeno del problema
MP thick-wall product center has a shrinkage cavity diameter 0.5-2mm
Análisis de la causa
thick-wall region interior shrinks after cooling but the surface is already solidified, cannot be fed; holding time insufficient, gate freezes prematurely
Solución
1) extend holding time until the gate completely freezes; 2) increase gate size to delay freezing; 3) product design to reduce wall thickness difference
Conclusión clave
shrinkage cavity is caused by thick-wall shrinkage and insufficient holding; extending holding is key
