Cope & Drag Patterns for the Automotive Industry

A manufacturer of antique automotive parts came to us with a special project. The customer had a set of left and right hand engine covers from an early 1900’s engine. The parts were originally manufactured by the Frontenac Motor Corp., who specialized in fabricating performance parts for models T at the turn of the century. These rare parts had no available engineering documents.

In order to maximize the integrity of the original design we digitally scanned the parts to create a 3D model, which was then used facilitate the tooling design process. The patterns and core boxes were then CNC machined, and dimensionally verified for accuracy. The patterns were machined from an epoxy molding board, and the core boxes were machined from a urethane plank. The patterns were then painted, assembled, and delivered to the customer, all with eight weeks of lead time. To learn more about this project, or the processes used to fabricate it, see the table below or contact us directly.
