PP Weld Line Strength
Fenómeno del problema
PP weld line strength is insufficient, multiple gates and hole positions, mold temperature and gate optimization.
Análisis de la causa
PP weld line strength is insufficient; multiple gates and hole positions; confluence temperature drops; mold temperature increase improves; gate position; venting management.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solución
①Increase mold temperature; ②optimize gate position; ③confluence temperature; ④venting management; ⑤strength test.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Mold temperature and gate are the main countermeasures for PP weld lines; testing ensures structural safety; management ensures appearance.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
