Expertise in Complete Manufacturing
LaserProdukt Gesellschaft für Auftragsfertigung mbH is a contract manufacturer based in Alfeld (Leine) specialising in metalworking and subassembly production. For more than four decades, the company has manufactured individual parts, prototypes, small and large series as well as complete, assembly-ready subassemblies to customer specifications. Its range of services includes laser cutting of sheets up to 2,000 × 4,000 mm and thicknesses up to 25 mm, tube and profile machining up to 500 mm diameter, waterjet cutting (2D and 3D) up to 100 mm material thickness, laser drilling and welding as well as laser marking. This is complemented by press brake technology up to 4 m bend length, welding processes (TIG, MIG/MAG, resistance and stud welding), machining (milling, turning, grinding) and surface treatment such as powder coating, anodising, galvanising and heat treatment. The offering is rounded off by design, engineering, NC programming, material procurement, quality inspection and logistics. Customers come primarily from mechanical engineering, plant engineering, apparatus engineering, automotive supply, electrical engineering and medical technology. At the site in the Limmer West industrial estate, around 17,000 m² of total space is available with approx. 3,000 m² of production and warehouse space; part of the energy requirement is covered by an in-house photovoltaic system.
