Stress Whitening at the Corners of PCTG Sheet Thermoformed Parts
Sorun Belirtisi
Whitening appears at the corners or bends of thermoformed products.
Neden Analizi
The material is excessively stressed at the corners, producing microcracks/cavities that scatter light and whiten, and the R angle is too small.
Çözüm
Increase the R angle ≥2mm; increase the sheet heating temperature; optimize the mold design to avoid excessive stretching.
Temel Çıkarım
PCTG stress whitening is a manifestation of local excessive deformation.
