Über Lee Spring
Lee Spring manufactures and distributes mechanical springs, wire forms, stampings and fourslide parts worldwide. The company produces compression springs, extension springs, torsion springs, wave springs (REDUX), die springs (HEFTY), plastic composite springs (LeeP), Belleville washers, constant force springs, battery springs, continuous length springs, spring guides and MIL-SPEC springs in stock and to customer specification. Manufacturing processes include coiling, fourslide forming, stamping, in-house tooling with EDM, as well as secondary operations such as grinding, plating, passivation, shot peening, electropolishing, tumbling, powder coating and stress relieving. Materials range from high-carbon steels (Music Wire) and stainless steels to chrome alloys, copper alloys, nickel alloys, Elgiloy and Ultem plastic composite. Lot sizes span from single prototypes to 10 million pieces. Founded in 1918 in Brooklyn, New York, the company operates 14 locations across the USA, Mexico, United Kingdom, Germany, China and India; the European network includes Lee Spring Germany in Lüdenscheid for stocking and delivery of standard and custom springs.
