Flat springs are resilient devices formed from flat strip material, as opposed to wound wire. Flat springs are used in many industrial applications, battery contacts being one of the most popular. Flat springs can also used as retainers, shields, clips, detents, contacts, wipers, brushes, and more.
Photo Etching is Cost-Effective for Complex Shapes
Photo etching is an effective solution for producing flat spring blanks because the process is so cost effective for producing complex shapes and very thin gauge materials. Flat spring components often require forming.
Materials Used for Photo Etch Flat Springs
Common materials used in the manufacture of flat spring forms are tempered alloys of copper, including beryllium copper and brass. Spring steels, such as C1075 and C1095 in the annealed state, are also commonly used.
