Overview

About Knupfer Metallverarbeitung GmbH

Who we are

The Knupfer Metal Processing GmbH is a sheet-processing supplier for the machinery and special machinery for air conditioning, ventilation and suction technology, clean room technology and the automotive industry and has worked for over 50 years. We manufacture sheet metal parts, machine covers, protective covers, enclosures, machine bases, machine body and complete assemblies from lot size 1 steel, stainless steel and aluminum. Our high-tech production in-house include: Laser Cutting (Automated high-bay warehouse) The following material can be cut: steel up to 25.0 mm, stainless steel up to 20.0 mm (oxide-free), aluminum up to 12.0 mm material thickness. The max. Machining size is 3000 mm x 1500 mm. All three stocking systems are connected to an automatic high bay warehouse with 220 storage bins (3 tonnes storage capacity). We are thus able to cut during the night shift without staff. Water jet cutting 5-axis machining of steel up to approx80 mm, stainless steel up to 80 mm, aluminum up to 100 mm - other materials such foam, plexiglass, plastics, glass, stone, sealing material, composite materials, wood, etc. possible. The max. Machining size is 3600 mm x 2000 mm Bending Pressing force of the CNC press brakes: 1 x 320t, 200t x 1, 1 x 36t ACB angle sensor available, 3-point bending is included as standard, Folding Machine in use Nibbling and punching Steel up to 6.0 mm, stainless steel up to 4.0 mm, aluminum up to 6.0 mm The installation of ventilation gills, beading, perforated grids, rows etc. is easily possible Welding (Manually or with robots) MIG / MAG and TIG, spot and stud welding (threaded bolts and sleeves), welding robot with rotating and tilting table for components up to 5000kg unit weight. These saws, laps, mech. Machining (milling, turning, drilling, threading), production of flange rings according to DIN 24154 and angle rings to DIN 24155, as well as special rings and segments and paint the assembly and completion according to the surface treatment (powder coating, galvanizing...).
