TPU Burrs and Flash
Sorun Belirtisi
Flash at product edges, appearing intermittently even though clamping force seems sufficient
Neden Analizi
TPU burr causes are complex: damp raw material reducing viscosity, excessive injection pressure, insufficient clamping force, mold wear, blocked vent holes, non-parallel platens, etc.; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Çözüm
①Check raw '2079851475616104451 and contamination first; ②Adjust injection pressure and speed; ③Check clamping force, mold wear and platen parallelism; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
TPU burr troubleshooting proceeds from easy to difficult; five routes progress stepwise: raw material, pressure, clamping, mold, equipment; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
