System integrator with integrated manufacturing
Ingenieurbüro Heinl GmbH is an engineering office with integrated manufacturing in Zolling near Freising and sees itself as a system integrator and system supplier. The company develops, designs and manufactures mechatronic and optoelectronic components, including sensors, fiber-optic components such as SERCOS transmitters and receivers, and electromechanical components such as high-current switches and power plant equipment. The services include design and engineering services in 3D CAD (ProEngineer/Creo), reverse engineering, 2D-3D conversion, fiber-optic fiber coupling with active optical alignment, assembly with bonding, potting and soldering work as well as cable assembly and testing to customer specifications. In the Prototyping business unit, small-series and prototype castings made of all common metals are produced using the sand casting process, with sand cores and molds produced by binder-jetting 3D printing; remanufacturing of spare parts, including redesign, is also part of the offering. Customers are found in power plant equipment and energy, automation technology, mechanical and plant engineering, and automotive technology for historic vehicles. The quality management system is certified to DIN ISO 9001:2015.
