The specialty foundry from Leipzig
Keßler & Co. GmbH is a specialty foundry in the Leipzig district of Großzschocher that has existed since 1995 and continues a 125-year foundry tradition at the site. The company produces castings as one-offs as well as in small and medium series with piece weights between 0.5 and 900 kg in low- and high-alloy iron and steel casting materials — as-cast, machined, or fully finished on all sides. The range of services includes heat- and acid-resistant steel castings for the chemical industry as well as the pump and valve industry, research and development of special alloys such as silicon castings, super duplex, ADI and C-ADI, prototype development, and traditional castings for bells and monuments. In addition, the foundry offers design and materials consulting with simulation calculations and stress calculations, post-casting finishing, heat treatment and surface finishing, and delivers castings from the pattern to the ready-to-install part. Melting is carried out in a medium-frequency furnace with a crane pouring ladle; quality assurance includes chemical analysis, hardness testing, microstructure determination, crack testing, dye penetrant testing and ultrasonic testing. Customers come from the chemical industry, the pump and valve industry, automotive engineering, mechanical engineering, shipbuilding, rail technology, and the offshore sector.
