DSTDP '2079851475616104452 demolding difficulty
ظاهرة المشكلة
DSTDP injection molded products have high demolding force, product deformation or scratching, demolding time accounts for 30% of the cycle
تحليل الأسباب
The adhesion force between DSTDP and the mold cavity is large; demolding draft insufficient <0.5°; cooling time insufficient, the product is demolded before fully solidified; ejection mechanism design unreasonable
الحل
1) Increase mold demolding draft to 1-2°; 2) extend cooling time so the product is fully solidified before demolding; 3) polish mold surface to Ra<0.2μm; 4) increase ejection area using a large-area ejector plate; 5) spray mold release agent (temporary solution)
الخلاصة الأساسية
Demolding difficulty is caused by adhesion and insufficient mold design; increasing demolding draft is the fundamental measure
