When the wall thickness of the injection molding parts is not uniform, the thick part of the wall cools more slowly than the thin part, so the thick part of the wall produces shrinkage holes.

It is theoretically difficult to eliminate shrinkage caused by uneven wall thickness, so uniform wall thickness should be made when designing parts. That is, the focus is on reducing the variation in wall thickness.
