Learning Injection molding design

by Mike Oxmaul

when wearplate is designed, is it necessary that there should be a very small gap between the core and cavity side of the mold right where the wearplate is joined? Since when the mold closes it is important that the wearplates touch first than the cavity and core plates itself for it to be a sacrificial component, i thought maybe there is a small gap, can you verify this? Thank you for the guide.

Wear strip Design

Hi Mike, if there is a gap then there will be uneven wall thickness in the part. I design my moulds with preload on the wear strip so that core & cavity can not move relative to each other.
