General information

Company profile	KROENERT manufactures innovative, reliable coating and laminating solutions for web-like materials such as paper, foil, film, cardboard and textile products such as glass or carbon fiber structures. The product range includes customized production and laboratory lines. We offer high-performance systems with web widths of up to 3,300 mm, coating thicknesses of more than 1 mm to a minimum of 100 nanometres and processing speeds of up to 1,600 m/min. Over the decades, we have built up state-of-the-art research and development capacities at KROENERT. In our Technology Centre, we develop innovative solutions together with our customers, we test and optimise – until we achieve the perfect result. Our experts use the Technology Centre for product development as well as for developing new process engineering.
Products & Services	KROENERT offers complete system solutions for the composites sector.These include customer-specific lines for the production of resin films and impregnation for the prepreg production of fiber construction materials. The EPCO machine concept is our specialist for the production of prepregs. Prepregs are manufactured in two steps – resin film production and subsequent impregnation. For mass production these steps are separated, as the resin film is produced at a higher speed than impregnation can take place. The resin film produced in the first process step is stored under refrigeration. Another machine is used to transfer this resin film to the textile fibers to be impregnated. As a rule, one resin film production line is sufficient to meet the capacity for three impregnation machines.
References and export activities	KROENERT has been serving the market for composite applications since 1950 and can draw on extensive experience with more than 50 machines delivered worldwide. KROENERT is a certified supplier to the aircraft and automotive industry (partners are e.g. suppliers to Airbus & Boeing). KROENERT also supplies all leading carbon fiber suppliers which offer prepregs as semi-finished products.
Target group	Our customers are manufacturers of carbon fiber directly, but also suppliers, who produce prepregs for lightweight construction applications on our lines and supply them to aviation companies, automotive manufacturers and manufacturers of wind turbines and hydrogen tanks.
Competitive advantages	KROENERT lines for resin film coating as well as carbon fiber impregnation offer the highest precision in temperature control, coating accuracy, running speed and substrate tension. The developed technology for grinding the heated rollers for coating as well as for calendering at process temperature results in highest running accuracy at the most used temperature in the application.
Ideal Business Partners	Suppliers of carbon fibers, as well as suppliers for the aerospace industry who use prepreg processes as well as other users for lightweight construction.
