Family-owned business with a history
Stöger & Gangkofer GmbH & Co. KG is a family-owned business in Eggenfelden specializing in CNC machining as contract manufacturing to customer order. The company produces components, assemblies and machine parts through drilling, milling and turning – from single parts to small series and large-scale series. A key focus is the machining of castings made of grey cast iron, aluminium castings and red bronze castings, as well as solid materials such as steel, stainless steel, tool steel, plastics and special materials such as bronze, copper and nickel alloys. Production takes place on 3-, 4- and 5-axis machining centres as well as turning machines with driven tools; workpiece dimensions up to Ø 600 x 1000 mm are possible. In addition, design and development using modern CAD/CAM technology are offered, as well as heat treatment and surface finishing such as anodizing, electroless nickel plating and hardening as downstream processing. The company's origins lay in plant and special machinery construction, structural steelwork and sheet metal processing.
