Overview

Coperion is a German industrial engineering company headquartered in Stuttgart-Feuerbach. Established in 2000 as a subsidiary of the Swiss industrial company Georg Fischer, it grew from Georg Fischer’s plant-engineering division and brought together businesses and product lines including Waeschle, Buss, and Werner & Pfleiderer. Hillenbrand acquired Coperion in October 2012. The supplied company history also records that Hillenbrand acquired K-Tron in 2010 and that K-Tron merged with Coperion in 2013, after which the combined business operated as Coperion K-Tron. The company organizes its offering around Compounding & Extrusion, Materials Handling, and Service. Its equipment and systems serve plastics, chemicals, food, and aluminium industries. Compounding and extrusion offerings include the ZSK twin-screw extruder, while Materials Handling covers bulk-solids processing and handling steps such as conveying, screening, mixing, storage, dosing, and thermal treatment. The company also supplies associated components, including rotary valves, diverters, and slide gates. Services span installation and commissioning, maintenance, spare parts, training, consulting, and modernization. Coperion’s business is international. The supplied history identifies Germany, Switzerland, the United States, and India as regional areas of focus in its early development, and reports that 75% of revenue was generated abroad in 2019. The source describes Coperion as a world-market leader in extrusion and compounding systems, bulk-material plants, components, and services. It names Ulrich Bartel as chairman of the management board. No current revenue, employee count, or detailed geographic breakdown is provided in the supplied evidence.

History

Coperion was established in 2000 as a subsidiary of the Swiss industrial company Georg Fischer, which made its plant-engineering division independent. The supplied history says the Coperion holding company was initially headquartered in nearby Konstanz. Georg Fischer contributed its Waeschle and Buss groups, together with Werner & Pfleiderer, which it had acquired from Thyssenkrupp. The company thereby combined businesses associated with systems and components for plastics processing. Its early regional focus included Germany, Switzerland, the United States, and India. The German-language account gives a founding-era scale of approximately 2,000 employees and about €400 million in revenue; these figures refer to that historical period, not current operations. Georg Fischer gradually divested Coperion between 2006 and 2007 to the British investment firm Lyceum Capital, following minority investments by West Private Equity Ltd and Westdeutsche Landesbank. In 2008, Hartmann Fördertechnik GmbH of Offenbach am Main joined Coperion. Hillenbrand, Inc. acquired Coperion in October 2012. The supplied account reports that Coperion employed approximately 2,500 people worldwide in 2014, including 1,200 in Germany. A further integration followed the acquisition of K-Tron by Hillenbrand in 2010. In 2013, K-Tron merged with Coperion, and the business subsequently operated under the Coperion K-Tron name. The company’s history also describes Buss Compounding Systems AG as having joined the Coperion group in 2001 and operated as Coperion Buss AG; in 2006 it became independent again following a management buyout. Coperion’s described business areas are Compounding & Extrusion, Materials Handling, and Service. Its ZSK product line is a co-rotating, closely intermeshing twin-screw extruder used for plastics production, finishing, and processing. The source traces ongoing development of the product line to the 1960s and says the range includes machine sizes from ZSK 18 to ZSK 420. Materials Handling covers bulk-solids processes from conveying and screening through mixing, storage, dosing, and thermal treatment, as well as components. The company’s service offering includes installation, commissioning, maintenance, spare parts, training, consulting, and modernization. The supplied account calls Coperion a world-market leader in extrusion and compounding systems, bulk-material plants, components, and services, and states that 75% of revenue came from abroad in 2019. It identifies Stuttgart-Feuerbach as the company’s headquarters and Ulrich Bartel as chairman of the management board.
