About WK Mechanik
Wolf Kreutzfeldt Mechanik GmbH (WK Mechanik) is a manufacturing company founded in 2003 in Wilhelmshaven that produces custom front panels, electronic enclosures, 19″ rack enclosures, mounting plates, identification labels and special parts made of aluminium and plastics. Machining is performed on six CNC milling machines (including DATRON) through milling, drilling, sawing and engraving, supplemented by pin presses (insert and press-through fasteners, grounding expansion pins per VG 96953-1-1) as well as assembly. Material thicknesses from 0.5 to 5 mm are processed; the material focus is deliberately on aluminium and non-ferrous metals, steel is not machined. For marking, digital printing, screen printing and engraving with RAL colour infill are available; anodising (EV1 silver, EV6 black) and powder coating are carried out through long-standing external partners. WK Mechanik operates exclusively in the B2B sector, manufacturing from one-off pieces and prototypes through small series to large series, and supplies customers from electrical engineering, mechanical and plant engineering, switchgear and control cabinet construction, testing and metrology, as well as research and development, from Germany and adjacent European markets. All production takes place at the Wilhelmshaven site.
