PMMA Extruded Sheet Cooling
Sorun Belirtisi
PMMA extruded sheets warp after cooling
Neden Analizi
Uneven cooling on both sides of the sheet causes inconsistent crystallization and shrinkage, producing warpage; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based on experience alone.; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Çözüm
Optimize calender roll temperature gradient; balanced cooling on both sides; stable haul-off speed; After adjustment, continuously sample 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
Sheet warpage is controlled by roll temperature gradient and haul-off stability; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.; include this case in the defect archive as a troubleshooting reference for similar future problems.
