OL – A family company presents itself

OL - A Family Company

At the beginning, there was a desire to develop injection molding machines and form a company with mass production capabilities. As the company founder Oskar Lehmann completed the first injection molding machine he developed himself, he also created a new business idea, converted the injection molding machine originally designed as a final product into a product machine, and has been manufacturing technical plastic parts since 1961.
Innovation and flexibility, together with passion and a feel for the right moment, were the trailblazers for a company operating internationally with success. At the location in Blomberg-Donop, over 180 employees today contribute daily to ensure that the success story will continue.
