Your team of HF MIXING GROUP

In good company

The companies of the HF MIXING GROUP – Harburg-Freudenberger, Farrel and Pomini – introduced innovative products and solutions to the market from the very beginning and are the leaders in mixing technology.

Harburg-Freudenberger With the manufacture and sale of kneading machines, Hermann Werner and Paul Pfleiderer laid the foundation for a new era in rubber processing. The “MASTICATOR“ kneading machine developed in 1900 quickly became a global standard. Independent sales agencies were set up in England, Austria and the United States along with branches in London, Paris, Moscow, Saginaw and Berlin. Werner & Pfleiderer’s further research and development quickly enhanced the growing reputation for technical excellence and high efficiency.

Farrel The long and rich history dates back to 1840 and epitomizes the Industrial Revolution in the United States. In the 1850’s, the Farrel Foundry began production of chilled iron rolls, a crucial component in rubber processing. A rubber calendar order from Henry B. Goodyear provided Farrel with valuable experience and opportunity. Through the merger of Birmingham Foundry and Farrel Foundry emerged the Farrel Corporation. In 1916, the revolutionary Banbury® Mixer was invented by Fernley H. Banbury, which is still today considered a standard in the tire industry.

In Freudenberg 1986, “Krupp Elastomertechnik“ was formed after Krupp took over “Werner & Pfleiderer Gummitechnik” and merged with the rubber and extrusion technology located in Harburg.

As the industry grew, Farrel was at the forefront of developments and innovations for the world’s most demanding tire and rubber companies. In 1963, the continuous mixer (FCM™) was developed and introduced to the thermoplastic processing industry. Another milestone was the acquisition of Francis Shaw of England, expanding the range of products by offering the Intermix®, a series of intermeshing technology mixers invented in 1934 by Rupert Cooke of Francis Shaw.

In spring 2005, L. Possehl & Co. mbH acquired the entire company from ThyssenKrupp Technologies. Under the new name, ”Harburg-Freudenberger Maschinenbau GmbH“, the company continued to be successfully and maintained its full product range.

Possehl & Co. mbH

The Farrel Chronicle Pomini The company was founded by Luigi Pomini in Castellanza/ Italy in 1886 and began by reconditioning knitters and machines used in cotton manufacturing. The key factor for Pomini’s growth was the development of the mechanical sector. In 1949, Pomini began manufacturing machines for the rubber and plastic industries.

1850: Farrel Foundry begins production of chilled iron rolls 1916: Banbury® Mixer developed and patented 1997: Acquisition of Francis Shaw and its associated product lines, including the Intermix® 2002: Acquisition of Skinner Engine Mixer Business

In the following years, Pomini’s success grew in Italy and abroad. In 1968, Pomini ventured into the system business by producing and delivering a complete mixing room. In 1984, Pomini acquired Giustina, a manufacturer of roll grinders. In 1988, Pomini was aquired by Techint Compagnia Tecnica Internazionale Spa.

2009: Acquisition by Harburg-Freudenberger Maschinenbau GmbH

The company’s main activities were the manufacturing of rolling mills for the steel industry, high precision grinding machines and machines for the rubber and plastic processing industry. In 1987, Pomini released the VIC™ principle – an innovation in intermeshing mixing systems. Pomini introduced the first twin screw dump extruder in 1995 which has become a standard in the tire industry.

Focused competence

The HF MIXING GROUP is a full subsidiary of L. Possehl & Co. mbH, Lübeck/ Germany. At our corporate locations, each company provides comprehensive services for modern mixing room technology.

Our range of products and services • High performance mixers in tangential and intermeshing designs • Single screw- and twin screw dump extruders • High performance mixing mills • Strip cutting machines • Hydraulic rubber bale cutters • Control and automation systems • Laboratory internal mixers and mills • Complete mixing room systems

Banbury® Mixer Farrel is the originator of the Banbury® Mixer. The Banbury® continues to be the top choice for tire producers and primary compounders around the world. Multiple stage mixing operations require rapid ingestion of feed materials and excellent dispersion capabilities for masterbatch mixing and optimum heat transfer for final applications. Drawing from the three companies within HF MIXING GROUP, the largest variety of rotors is offered to meet specific customer requirements.

The product range of HF MIXING GROUP is unique. HF MIXING GROUP is the leading manufacturer of tangential and intermeshing mixing systems for technical rubber goods and silica based compound processing for the tire industry.

FCM™ Continuous Mixer The Farrel FCM™ is based on a proven intensive mixing concept for processing efficiency, extreme versatility, dependability and profitability. Intensive material shear is performed by kneading between the rotors and chamber wall and by the rolling action of the material itself. The FCM™ is adept at processing polyolefin based compounds with high levels of mineral fillers, additives and color masterbatches, polymer-elastomeric blends and applications requiring high intensity mixing with the lowest processing temperature.

The Intermix® The Intermix® is a performer in both rubber and plastics applications and is ideal for technical rubber goods products as well as tire compounds. The PES5 rotors of the Intermix®, with unique intermeshing nog geometry assure even distribution and dispersion of material ingredients. The rotor configuration, along with optimized water passages, creates an enhanced material flow, optimized cycle times and fewer mixing passes for heat sensitive materials. Another technical highlight is the VIC™ which provides an additional and unique processing parameter. The VIC™ principle allows for adjusting the clearance between the rotors during the mixing process.

Tandem Technology The successful introduction of tandem technology to the tire industry is a quantum leap. In virtually every step within the mixing room, there is significant potential to improve quality and efficiency through tandem technology. We believe in the future, tandem technology will be the new standard in many areas of the tire industry.
