About SLT Sauerland Laser Technik
SLT Sauerland Laser Technik GmbH in Kirchhundem specialises in the laser processing of sheet metal and tube. The portfolio includes 3D laser cutting and welding of large and small components, 3D tube processing with mechanical machining in the same clamping setup, 2D laser cutting and nibbling, laser marking, bending and forming, as well as the joining of assemblies by laser, MAG, MIG, TIG and resistance welding. In addition, laser powder deposition welding (LMD), mechanical joining methods, assembly of subassemblies, surface treatment via a partner network, machining, and 3D printing with metal and plastic are offered. Materials processed include steel, aluminium, stainless steel, copper, brass and titanium. Customers come from the automotive, structural steel, renewable energy, charging systems and electronics industries; a focus is on complex metal constructions for inverters and energy storage systems. Together with its sister company SMT Sauerland Metall Technik, the company employs around 140 staff at three sites with a total of approximately 10,900 sqm of production area.
