HIPS Product Stress Whitening
ظاهرة المشكلة
HIPS products whiten at bending or stressed positions.
تحليل الأسباب
The rubber phase in HIPS separates from the matrix interface under stress to form crazes; snap-fits and bending positions are high-incidence areas.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
الحل
①Optimize the structure to avoid local overstress; ②enlarge fillets; ③select high stress-whitening-resistant grades; ④control assembly force.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
HIPS stress whitening is related to rubber phase behavior; structural optimization is more effective than process adjustment.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
