Example Factories


Do you have any sample factories I can show my students to get them excited?


Sure do…. see the links below!  Be sure to send us any that you and your students do… we would love to feature them here!

CalPoly’s 2015 Factory that Assembles the lid to a container that was built in the previous unit of the CIM course.

That’s right…. CalPoly built TWO factories this year! This one does a powder coating operation on a metal part.
