Uneven Density of PBT Injection-Molded Products
Fenómeno del problema
The density of various parts of the product differs, affecting mechanical properties and uniformity.
Análisis de la causa
The filling front flow speed is inconsistent and the pressure transmission is uneven; the holding compensates for shrinkage to different degrees in different regions; the cooling rates differ.
Solución
Optimize the gate position to achieve balanced filling; increase the holding pressure; make the mold temperature uniform.
Conclusión clave
PBT density uniformity is the basis of quality consistency.
