Design Cube

One of the best ways to learn about our injection molding process is to have an actual plastic part in your hands to explore. That’s why we created the Design Cube, which shows part features that are too thin or too thick, bad bosses, right and wrong ribs, and other considerations to be mindful of while designing parts for injection molding.
