About SAUR Werkzeugbau
SAUR Werkzeugbau GmbH is a tool and mould making company founded in 1977 by Werner Saur, headquartered in Lauffen am Neckar. Its core competence is the development and manufacture of complex injection moulding tools, including 1K, 2K and 3K tools, LSR tools, insert tools, unscrewing tools and stack tools. The complete production of injection moulds takes place in-house: from consulting including injection moulding simulation (Moldex 3D) and 3D design (Solid Works) through to manufacturing and final assembly. Tools up to 800 mm × 800 mm and 3.0 t are produced, with larger builds realized together with partner companies. In addition to tool making, the company offers contract manufacturing services such as milling, turning, grinding, die sinking EDM and wire EDM. It serves industries such as the automotive, electrical and household appliance industries, sanitary engineering, medical technology, control, regulatory and metrology technology as well as consumer goods, cosmetics, construction, toys and the watch industry.
