MP '2079851475616104452 difficult demolding
Sorun Belirtisi
MP injection molded products have large demolding force, products deformed or scratched, demolding time accounts for 30% of the cycle
Neden Analizi
MP has large adhesion to the mold cavity; draft angle insufficient <0.5°; cooling time insufficient, product demolded before fully solidified; ejection mechanism design unreasonable
Çözüm
1) increase mold draft angle 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)
Temel Çıkarım
difficult demolding is caused by adhesion and insufficient mold design; increasing the draft angle is the fundamental measure
