Performance from the provinces – for worldwide success
Kumminger & Öllerer Metalltechnik GmbH is a specialist company for the manufacture of metal components, in particular prototypes and small series. Founded in 2014 and based in Ainring/Mitterfelden in the far south-east of Bavaria, the company manufactures components with 15 employees for customers from the automotive industry, vehicle construction, motorsport and mechanical engineering. Its services include design, laser cutting, CNC sheet metal bending, various welding processes including robot-assisted welding, 5-axis CNC milling from solid material, turning, tube bending as well as heat treatment such as stress-relief annealing, solution annealing, artificial ageing and hardening. These processes are complemented by laser marking, blasting, vibratory finishing and surface grinding. A broad material stock of tubes, sheets, profiles and bars enables immediate production without loss of time. According to the company's own statements, customers value its precise working methods, punctuality and creative pragmatism.
