Sketching Lifter Mold Volumes

A lifter is another mold component that helps account for
undercuts of the inside of the reference model geometry.
• Lifters usually move at an
angle.
• Lifters are usually long and
narrow.

A lifter is another mold component that helps account for undercuts of the
inside of the reference model geometry. Because mold components are
ultimately created from mold volumes, you can use sketch-based features
to create lifter mold volumes in the mold model.
A lifter is usually attached to the moving side of the mold. It moves at an
angle to free the plastic that comprises the undercut inside the model. Due to
their function, lifters are normally long and narrow.
