About us
B&K GmbH, based in Lindlar, is a contract manufacturer for mechanical manufacturing and mechanical engineering. Founded in 2005, the company employs 20 staff and manufactures components and assemblies on 1200 m² of production space in the Klause industrial estate. The core competence lies in the mechanical manufacturing of mechanical engineering components for packaging machines, textile machines, jig and fixture building as well as general mechanical and plant engineering. Manufacturing comprises CNC milling on machining centres with CAD/CAM linkage, CNC turning technology from single parts to medium series, NC and CNC drilling technology, 8-axis CNC bending technology, welded constructions (TIG, MAG, MIG, spot welding, stud welding) as well as sawing technology. Workpieces are manufactured from a single source – from material procurement via surface treatment through to the fully assembled unit. Steel, aluminium, brass, red brass, stainless steel and plastics are available from stock in standard dimensions.
