About Ernst+Landerer
Ernst+Landerer GmbH & Co. KG has been manufacturing precision cast parts in aluminium gravity die casting at its Balzhausen site in Bavaria since 1968. The company covers the entire process chain in-house: die making with steel permanent moulds including sealing grooves and sealing surfaces, gravity die casting with tightened dimensional tolerances, casting-in of inserts such as threaded bushings, pins and steel rings, casting fettling, heat treatment, mechanical casting machining as well as surface treatment with wet and powder coating and tumble finishing. Components with unit weights of up to approx. 13 kg are produced, which also meet pressure-tightness and oil-tightness requirements; production lot sizes start at approx. 200 pieces. The around 75 employees supply customers from mechanical engineering (hydraulics, machine tools, vacuum and pump technology, transformer construction), construction technology, drive technology, medical technology and transport technology. The quality management system is certified to DIN EN ISO 9001; on the 20,000-m² site with 8,000 m² of production space, the company also trains apprentices.
