About JELBA
JELBA Werkzeug- und Maschinenbau GmbH & Co. KG is a manufacturing company based in Hauzenberg since 1990, operating in the tool and mechanical engineering sector. The company manufactures complete systems, special machinery and precision components to drawings, datasets, samples or with full design engineering. The value chain includes CNC milling (over 20 machines and machining centres), CNC turning (10 machines as well as conventional lathes), cylindrical and surface grinding (five CNC and one conventional machine) and manual welding using MIG, MAG and TIG. Components up to 80 tonnes unit weight are manufactured, assembled and commissioned; in addition, CAD/CAM systems, design consulting, installation and customer training provide a service beyond contract manufacturing. From 2025, Hall 10 with 300 m² cleanroom, cleaning systems as well as ventilation and filtration technology will be available to customers from the optics and semiconductor industries. Around 290 employees work at the Hauzenberg site in Lower Bavaria.
