Annual average

Fifteen companies, five product areas and three business units are united under the umbrella of HF Group, which, together with the parent company Harburg-Freudenberger Maschinenbau GmbH, has been a wholly-owned subsidiary of L. Possehl & Co. mbH since 2004. With Harburger Eisenwerke AG founded more than 160 years ago, the group with its business units HF Mixing Group, HF TireTech Group and HF Press+LipidTech can look back on a longer history than most other mechanical engineering companies in the market.

The company keeps expanding its comprehensive know-how by constantly investing in research and development of its machines and software solutions. This has made Harburg-Freudenberger the global leader in developing and manufacturing special machines for the rubber, tyre and cooking oil industries. The reliable, made-to-last machines have been designed to meet specific customer requirements.

Both internal growth and various strategic acquisitions ensured that the HF Group developed into the leading global key player in the tyre industry. Through the most recent acquisition of the US-based company Mesabi Controll Engineering Ltd. in 2017, another step forward was made in the field of future-oriented digitisation and machine control. At its business location in Hamburg-Harburg, the group is investing in additional growth until 2020. On a total area of 20,000 square metres, a 7,700-square-metre office building with an adjacent assembly and technology centre of 5,500 square metres are under construction. In Freudenberg, several tens of millions of euros will be invested in modernising and extending the HF Mixing Group’s headquarters in the coming years. These two major investments follow the new building and expansion projects we completed at our sites in the US, in Croatia and Slovenia in the past years.
