PA6 Flash from Parting Line Wear
Fenómeno do problema
After a period of use, flash appears at the parting line of the PA6 mold and gradually worsens
Análise das causas
PA6 low-viscosity melt is sensitive to parting line gaps; after parting line wear or plate deformation the gap enlarges, and melt escapes to form flash that worsens with wear; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solução
Check parting line fit and plate parallelism, and re-fit worn surfaces; appropriately reduce injection pressure, and for machines with insufficient clamping force switch to a larger tonnage; strengthen mold maintenance
Conclusão principal
Worsening flash mostly originates from mold condition deterioration, and mold repair is more fundamental than machine adjustment; 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 similar problems in the future
