Clever teaching tool for plastic moulding added to the shop June 20, 2018 14:06

Today we added a clever teaching tool to the shop that can help designers, engineers, and students to design better plastic components.


This moulded plastic piece includes features which 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.

You can see the product here. We also have a sample set with 20 moulded samples of different plastics.
