PA12 Product Weld Line

Fenómeno del problema
Low weld line strength.
Análisis de la causa
Low front temperature and poor fusion; PA12 crystallizes fast and the front cools down.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solución
①Increase melt and mold temperature; ②optimize gate position; ③increase convergence speed; ④set overflow well.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Weld lines rely on temperature and gate management.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a troubleshooting reference for subsequent similar problems
