System supplier for electrical and mechanical engineering
WEZEK GmbH is a system supplier for electrical engineering, control technology, automation as well as machine and fixture construction, headquartered in Steinebach/Sieg (Rhineland-Palatinate) with a branch office in Leverkusen. Since 1973, the company has been engaged with more than 100 employees at two locations in the planning, development, manufacture and commissioning of customised solutions for the manufacturing industry. In machine and fixture construction, a focus lies on the handling and further processing of plastic injection-moulded parts, including robot cells (clipping, adhesive application, flame treatment), handling systems, special-purpose machines and toolmaking. Control technology covers hardware and software engineering (PLC Siemens TIA Portal, Beckhoff), special control construction from operator enclosures to large-scale systems, and robot integration with systems from Yaskawa, ABB and KUKA. Further service areas are electrical installation, measurement-control-regulation technology/building automation, data centre infrastructure, network technology, PV systems and e-mobility, as well as technical service with maintenance, retrofit and inspections in accordance with DGUV Regulation 3. Customers include companies from the automotive, steel, pharmaceutical, chemical and food industries, machine and plant engineering, water treatment and data centres.
