Evans Metal Stamping, Inc/Evans Tool & Die, Inc

A manufacturer of camping and recreational products was in need of a custom metal stamped, stainless steel component for a new line of fireplace and camping lighters. They required a large order and needed a company that could handle the high volume and maintain the level of quality that the product demanded.

The part, a stamped linkage spring, was to be constructed of 301 stainless steel, 3/4 hard, and maintain tolerances of ±.002” and .002” of parallelism. Isometric and 2D CAD drawings were supplied by the customer, and Evans designers created the 3D models in Inventor.

Once we created the tooling and the first articles approved, we developed an inspection plan to maintain quality and began production. Our 75 ton Bruderer press is currently producing 36,000 of these parts daily.
