Macomb College has the capacity to inject small parts using their 50-ton VanDorn injection molding machine.

We started our Macomb coin project by designing the art. This particular piece was developed in CimatronE because we didn’t have Artcam yet. We converted our design to IGES to give to Tenibac Graphion for laser engraving the steel mold. But Iwelearned, however, that all they require is a picture. Their software reads bitmap files and converts to laser language.

The mold inserts below were laser engraved by Tenibac Graphion on their $500,000 laser. Unable to produce sharp corners using traditional machining methods, our options were laser and EDM. This is something we teach our students when processing jobs.
