About us
TEPROSA GmbH was founded in 2009 in Magdeburg and is a contract manufacturer for laser processing. The company, with more than 30 employees, offers contract manufacturing in the areas of laser cutting of sheet metal and thin-gauge material, metal and sheet metal processing, and 3D-MID technology. The portfolio includes laser cutting of electrical steel, the production and stacking of stator and rotor stacks, the Backlack (self-bonding coating) process, laser engraving and marking, shims, embossing stamps, electrode and battery foils, and cell connectors. In the 3D-MID field, TEPROSA produces three-dimensional circuit carriers through laser direct structuring (LDS), selective plastic metallization, and 3D assembly of components. Customers come from the automotive industry, medical technology, mechanical engineering, the electric motor and e-mobility sectors, as well as the battery and electronics industries. The company manufactures at its headquarters in Magdeburg and, among other things, supplies shim customers worldwide.
