What does a feature that is perpendicular to the direction of mold open/close require?
Understand the Problem
The question asks what a feature perpendicular to the direction a mold opens and closes requires. This involves understanding the mechanics of a mold and what components are necessary for features deviating from the main mold movement.
Answer
Action
A feature perpendicular to the mold opening direction typically requires an action, such as a side-action cam or lifter, to create the feature in the molded part.
Answer for screen readers
A feature perpendicular to the mold opening direction typically requires an action, such as a side-action cam or lifter, to create the feature in the molded part.
More Information
Features that are not parallel to the mold's opening and closing direction are called undercuts. Undercuts can be internal or external and require additional mechanisms (actions) to be molded correctly.
Tips
It is a common mistake to think that all features can be molded with a simple two-part mold. Features like undercuts need more complex mold designs.
