Designing Complex Features for Molded Parts

Undercuts

Create complex geometries such as clips, openings, and pass-through features without compromising manufacturability. Learn how cams and inserts can help accommodate undercuts in molded part designs

Read Tip

Bump-offs

Reduce tooling complexity for small undercut features by incorporating bump-offs where geometry and material selection allow. Learn when this approach may be a practical alternative to side-actions.

Read Tip

Side-actions

Incorporate openings, windows, and other undercut features that cannot be formed in a straight-pull mold. Learn how side-actions can expand design flexibility while supporting manufacturability.

Read Tip

Shut-offs

Create complex molded geometries and pass-through features without additional mobile tooling components. Learn how shut-offs can be used to accommodate undercuts and simplify mold construction.

Read Tip

Core and Cavity

Improve manufacturability and part quality with thoughtful core and cavity placement. Learn how mold design decisions can influence appearance, performance, and overall molding outcomes.
