About brandgroup
Brand KG (brandgroup) is an owner-managed, internationally positioned manufacturer of technical springs and wire bending parts with over 100 years of experience. The portfolio includes compression, extension, torsion, torque, leg, flat spiral and arch springs, torsion bar springs as well as completely assembled spring modules; in addition, the group develops and manufactures mechatronic and thermomechanical system solutions, electronics for e-mobility and busbar technology as well as products made from shape memory alloys and medical technology. Manufacturing is performed cold using CNC winding, coiling and bending processes with wire diameters from 0.80 to 14.00 mm, followed by grinding, shot peening, heat treatment, nitriding, setting, surface coating (galvanizing, zinc flake, KTL, MKS) and assembly. All common spring wire grades are processed, including Super-Clean oil-tempered valve spring wire, stainless steel grades, reinforcing steel, shape memory alloys, fiber composites and plastics. Customer industries are primarily automotive, construction, household appliances, agriculture and forestry, rail industry, mechanical and apparatus engineering, medical technology and e-mobility. The brandgroup delivers worldwide from its locations in Anröchte (headquarters with development and materials laboratory), Erwitte (automotive production), Lüdenscheid (Märkisches Federnwerk) and Siemianowice Slaskie (Brand Springs Poland).
