Company
SCHLEIFSTEIN Maschinentechnik GmbH (smt), headquartered in Siegen, is a medium-sized, globally oriented manufacturer of machines and systems with over 120 years of experience in mechanical engineering. The company develops and manufactures machines and systems in three core areas: press automation (blank loaders, press linking, parts handling), surface technology (coil and blank washing machines, cross-brushing machines, spray-oiling systems) and forming technology (head production systems for flanging and beading, shipyard presses, segment presses and special shears). The value chain includes design using modern simulation software, in-house mechanical manufacturing, an own welding shop, control and visualization technology, assembly and commissioning. Served industries include automotive, press plants, head production, steel service and shipbuilding. The offering is complemented by retrofits, used machinery, maintenance and remote maintenance, with locations in the USA and China.
