About A. Liersch GmbH
A. Liersch GmbH from Bad Oldesloe is a special machinery construction company that has evolved since 1946 from the sewing machine to the fully automated production line. The company plans and manufactures turnkey special systems and individual modules for processing textiles, nonwovens and fleeces, including sewing robots, high-performance sewing workstations, ultrasonic, hot-air and hot-wedge welding technology, seam testing stations, camera systems for quality assurance, robotics for material feeding and loading/unloading as well as fully automatic cutting systems. The value chain ranges from feasibility studies, patent research and specification creation to prototype manufacturing in-house (3D printing, CNC milling, plasma cutting) and design, through to programming with control cabinet construction, FAT/SAT, commissioning and cycle time optimization. Customers come from automotive (seat belts, airbags, sealing technology), filter technology, home textiles, aerospace, construction materials, military, medical/pharmaceutical and apparel. The company delivers worldwide, with over 300 customers worldwide stated, and covers around 70% of its energy needs itself through photovoltaics and electromobility.
