Lifters allow demolding of undercuts without any intersection and without using sliders.

The sideways moving direction under a certain angle during the ejection process releases the undercut geometry and the plastic part can drop out of the mold base without any damage.

The movement of the lifter is driven by the ejector plate package, so its reach is more limited compared to the free movement of a slider.

Select the Trim to quilt/refmodel option to trim the lifter bar to either the reference model or a defined trim quilt.
