Expertise since 1862
Wilhelm Julius Teufel GmbH is a family business founded in Stuttgart in 1862, headquartered in Wangen near Göppingen in the Stuttgart region. The company manufactures and distributes prosthetic components and orthosis concepts for orthopaedic technology, including prosthetics (liners, lock systems, prosthetic feet such as the META family), orthotics, electronic fitted parts such as the actively motor-assisted Intuy Knee knee joints as well as orthopaedic shoemaking. The in-house service production produces milled models, test fittings and plastic finished parts, among others in plastics technology, fibre composite technology with carbon fibre and prepreg technology as well as DESIGN Liner. Manufacturing processes include thermoforming, deep drawing, CNC manufacturing for modular fitted parts, laminating technology, plaster technology and the processing of two-component polyurethane rigid foam. The offering is complemented by seminars, support and the distribution of certified partners. Sales representatives are on site in Austria, Switzerland and Poland; distributors serve other European countries.
