CEF injection molded part ejector white marks
Sorun Belirtisi
White marks appear at the ejector pin position of the CEF injection molded part, ejector whitening affecting the appearance
Neden Analizi
Excessive ejector pin force causes local compression deformation and whitening; insufficient cooling time, the part is ejected before being fully solidified; the ejector pin area is too small and the stress is concentrated
Çözüm
1) Extend the cooling time so that the part is ejected after being fully solidified; 2) Increase the ejector pin area and use an ejector plate instead of small ejector pins; 3) Reduce the ejection speed to reduce the impact force; 4) Increase the draft angle to reduce the ejection force
Temel Çıkarım
Ejector whitening is caused by excessive ejection force and insufficient cooling; increasing the ejector pin area and extending the cooling time are the key
