ASA Extruded Sheet Surface Defects
Sorun Belirtisi
【Problem Phenomenon】ASA extruded sheet surface ripples, uneven thickness
Neden Analizi
Die gap unevenness, melt temperature fluctuation and three-roll calender asynchrony cause surface defects; ASA sheet surface quality is the key for outdoor application; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Çözüm
Die gap precisely adjusted; melt temperature stably controlled; three-roll temperature and speed matched; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
ASA sheet surface relies on three stabilities of die, melt temperature, three-roll; 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 subsequent similar problems
