PMMA Extruded Sheet '2079851475616104458
Sorun Belirtisi
Extruded sheets tear and have uneven thickness during '2079851475616104458, and the sheet deforms permanently between clamps
Neden Analizi
Extruded sheet '2079851475616104458 temperature is 270-350°F (about 132-177℃); multiple independent clamps deform the sheet between clamps; improper infrared heater position causes center overheating
Çözüm
①Use continuous clamps instead of independent clamps for '2079851475616104458; ②optimize infrared heater position to prevent center overheating; ③control forming temperature and manage the softening zone above 220°F
Temel Çıkarım
Clamps and heating in extruded sheet '2079851475616104458 guarantee geometric uniformity; continuous clamps plus a uniform heating field; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
