About SLITEQ
SLITEQ GmbH was founded in 2010 by Dipl. Ing. Martin Pfeiffer, who had previously worked for around 25 years as a design engineer and head of design in film slitting and winding technology. Based in Waldbröl, the company develops and implements customer-specific machines and systems as a full-service provider: film slitting and winding equipment with longitudinal and cross cutters, winders, coating systems and embossing units, special-purpose machinery such as assembly and testing machines, conveyor and feed technology as well as special crane systems under the Pfeiffer-Krane brand, including crane service. The portfolio is complemented by engineering services ranging from planning and 3D/2D design, FEM calculations (ANSYS, Hypermesh), structural analysis with RFEM and structural engineering through to risk assessments, procurement, assembly support, electrical planning, commissioning and CE documentation. In-house manufacturing is carried out together with selected cooperation partners holding the corresponding welding qualifications. Materials are mainly steel, aluminium and stainless steel. Customers include companies from film production and processing, plastics and paper processing, the non-ferrous metals industry, the steel industry, the automotive, chemical and food industries as well as plant engineering.
