Molding Part Geometry Summary

The geometry of a part is a big factor in mold design. The design can be a lot simpler if the molded part can be ejected freely, with no horizontal hole shapes or undercuts that prevent normal ejection. However, when this is not possible, special system designs are required such as:

  1. Lifter systems to free undercuts
  2. Core pull systems for horizontal or angular hole shapes
  3. Slide action systems to free horizontal hole shapes or undercuts
