HDPE Warpage Deformation
ظاهرة المشكلة
Product warpage is out of tolerance, flatness is poor, and assembly gaps are uneven
تحليل الأسباب
HDPE warpage originates from uneven cooling, wall thickness differences, and molecular orientation; anisotropic shrinkage makes deformation directional; rapid cooling locks in stress and aggravates warpage; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
الحل
①Uniform wall thickness ±10%; ②balanced arrangement of cooling water channels; ③control cooling rate at about 3℃/s; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
HDPE warpage is a comprehensive test of shrinkage management; uniform wall thickness plus balanced cooling plus controlled cooling rate; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
