DSTDP injection molded product ejector whitening
Sorun Belirtisi
DSTDP injection molded product shows white marks at ejector pin positions, ejector whitening affecting appearance
Neden Analizi
Ejector pin force too large causing local compression deformation and whitening; cooling time insufficient, product ejected before fully solidified; ejector pin area too small, stress concentration
Çözüm
1) Extend cooling time so the product is fully solidified before ejection; 2) increase ejector pin area, use ejector plate instead of small ejector pins; 3) reduce ejection speed to reduce impact force; 4) increase demolding draft to reduce ejection force
Temel Çıkarım
Ejector whitening is caused by excessive ejection force and insufficient cooling; increasing ejector pin area and extending cooling time are key
