MP surface stress whitening
Sorun Belirtisi
MP product stressed regions show surface stress whitening, affecting appearance and strength
Neden Analizi
MP under local stress, molecular orientation causes refractive index difference, whitening; product internal stress concentration regions
Çözüm
1) reduce injection speed to reduce orientation stress; 2) annealing at 80°C/2h to release stress; 3) product design avoiding stress-concentrating sharp corners
Temel Çıkarım
stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
