PA12 Melt Temperature Graded Setting

Fenómeno do problema
【Problem phenomenon】Pure material and reinforced PA12 used the same temperature, resulting in insufficient filling or overheating degradation
Análise das causas
The Grilamid processing window is clearly graded: non-reinforced 220-260℃, reinforced 240-290℃; reinforced grades have high viscosity and need higher temperatures to ensure flow and fiber dispersion, and applying the low temperature of pure material immediately causes insufficient filling
Solução
Set melt temperature by grade category: non-reinforced 220-260℃, reinforced 240-290℃; refine for specific grades by checking the data sheet; replace the temperature card simultaneously when changing material
Conclusão principal
PA12 temperature is set in grades according to whether it is reinforced or not, and the temperature card must be changed when changing grades; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
