Global market leader for tyre production systems with a long tradition

Twenty companies and three business units are currently united under the umbrella of the HF Group, which, together with the leading 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 ­FoodTech can look back on a longer history than most other mechanical engineering companies in the market.

By continuously investing in R & D activities promoting the development of innovative machines and software solutions, Harburg-Freudenberger is constantly expanding its comprehensive know-how, which made the company a worldwide leading developer and manufacturer of special machines for the rubber, tyre and food industries. With its subsidiaries Farrel based in the US and Pomini in Italy, the group of companies is also a major supplier for the plastics-processing industry. The customised machines are designed for longevity and ultimate reliability.

Both internal growth and various strategic acquisitions in the past years ensured that the HF Group developed into a leading global key player in the tyre industry. By acquiring the US-based company Mesabi Control Engineering Ltd. in 2017, another step forward was made in the future-oriented fields of digitisation and machine control. The founding of the FoodTech product segment at the beginning of 2021 further expanded the group’s business activities. The company already has and will continue to invest several tens of millions of euros in the new-building and expansion of its offices and production facilities at the two main sites in Hamburg-Harburg and Freudenberg in the course of the current financial year. These two major investments are a continuation of previous investments in the new-building and expansion of the company’s business sites in the US, Croatia and Slovakia, which makes the group not only one of the most significant but also one of the most modern suppliers for the rubber and plastics industries.
