Large differences in weight and dimensions between cavities, unstable quality
Fenómeno del problema
Large differences in weight and dimensions between cavities, unstable quality
Análisis de la causa
Unbalanced runner layout, flow path length differences between cavities
Inconsistent gate sizes between cavities
Cooling condition differences between cavities
Venting condition differences between cavities
Cellulose acetate butyrate fluidity is sensitive to pressure, small differences amplified
Solución
Balance runner layout to ensure equal distance for each cavity
Unify gate sizes of each cavity
Unify cooling conditions of each cavity
Unify venting design of each cavity
Optimize runners so all cavities fill simultaneously
Conclusión clave
Multi-cavity requires balanced runners and unified cavity conditions
