Plastic design teaching tool

This moulded plastic piece includes features that illustrate a number of good and bad practices when designing components for plastic injection moulding.

The blue side shows the best way to design different features, which result in lower tooling costs and a shorter moulding cycle. The orange side shows examples of bad design practices.

By studying the design, you can learn about the importance of uniform wall thicknesses, draft angles, cores, ribs, and other features. You can also see clever examples of how to implement undercuts, snap fits, axle mounting holes, and ventilation grids.

It is moulded in polyethylene.
