POM Flash
Sorun Belirtisi
Flash at the parting line of POM parts, gradually worsening
Neden Analizi
POM melt has low viscosity and good flowability, overflowing through even tiny parting line gaps; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Çözüm
Parting line fitting inspection; clamping force calculation; grade injection pressure to reduce end-stage pressure; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
Flash of low-viscosity materials is controlled by mold precision and pressure grading; 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
