Shutoff in Plastic Injection Mould  Shut-Off angle is applied for prevent the mold parts (Core and Cavity) from crashing into one another if there is any slight misalignment upon mold parts closing. Shut-OFF angle also prevent galling that would occur if vertical metal faces were rubbing against each other. Eg.  Note: A draft angle exists for purposes of part release, while a shutoff exi...
