About Us
August Weckermann KG is a family-run company based in Eisenbach in the Hochschwarzwald since 1885. The company manufactures precision turned and milled parts, precision engineering components and watch parts, and specializes in high-gloss, diamond-finished surfaces (Ra 0.01), produced on 100 special machines. The vertical range of production extends from simple turned parts to complex assemblies including assembly and retail-ready packaging; additionally, forming processes, marking, surface treatment and finishing are offered. Brass alloys, copper, bronze, aluminium, steel and stainless steels as well as machinable plastics are processed. Core customers come from fittings, sanitary ware, valve technology, optics, jewellery, luxury Hi-Fi and cosmetic packaging, including renowned sanitary manufacturers. At the headquarters with administration and logistics centre, as well as at the second location occupied in 2024 in Eisenbach-Oberbränd (3,200 m²) with nearly energy-autonomous production (AW-Vision23), 151 employees generate a revenue of €29.7 million and a material throughput of 4,000 t per year.
