Molds & Tooling

Ejector whitening/ejector deformation of products
Problembeschreibung
The product surface at ejector pin positions turns white and bulges or dents and deforms
Ursachenanalyse
Mold draft angle is insufficient (recommended >1°); ejection area is too small or ejection speed is too fast; bonding force between the product and the mold surface is too large
Lösung
Increase draft angle to 1-3°; increase the number of ejector pins and ejection area; reduce ejection speed and use release agent in combination
Wichtigste Erkenntnis
The ejection system design needs to fully consider the distribution and magnitude of demolding force
