Centrifugal chip cleaning

One of our most common types of scrap is swarf produced during aluminium machining. As these chips contain a high proportion of lubricant residues, they need to be pre-processed to prevent them from burning in the furnace and producing high levels of various toxins and emissions. Traditionally, this is done using a thermal chip processing plant, which is very energy-intensive to operate. Oetinger has therefore invested in centrifugal chip cleaning systems that separate the lubricant instead of burning it. After the installation of the first centrifugal plant in Weißenhorn in 2020 and the commissioning of a second plant in Neu-Ulm by the end of this year, we will save up to 3500 t of CO2 per year.
