Cope & Drag Alignment Inserts: Where it all began

PHOTO: Cope & DragIn 1982, Adolf developed his first alignment insert. He recalls, the simplistic idea of having two inter-connecting conical diameters creating impressions within the Cope & Drag halves. Utilizing this innovated idea he manufactured tooling to create the Cope & PHOTO: AdolfDrag Alignment Inserts, which create a perfect line system for multiple tooling processes. Such as, cope and drag match plate, match boards and molding boxes for no bake, greensand and automated molding processes.
