About Bien Metallverarbeitung
Bien Metallverarbeitung GmbH in Eriskirch on Lake Constance is a mid-sized contract manufacturer for sheet metal and metalworking. The company produces one-off parts as well as small and medium series and offers laser cutting (sheet formats up to 1250 x 2500 mm, steel up to 10 mm, stainless steel up to 8 mm, aluminium up to 5 mm), waterjet cutting as a cold cutting process (formats up to 2000 x 3000 mm, material thicknesses up to approx. 80 mm, burr-free and without thermal influence), bending on a 7-axis CNC press brake with long stroke (bending length 2500 mm, edge height 500 mm), rounding and rolling of tube blanks, funnels and cones, saw cuts up to Ø 323 mm as well as milling on a MAHO MH700 S with pallet changer. In addition, there are welding processes (TIG 141, MAG 135/136, spot welding, stud welding) and apparatus and vessel construction with TÜV-certified vessels. With approval per AD-2000-Merkblatt HP0 and DIN EN ISO 3834-3, the company manufactures in accordance with the Pressure Equipment Directive 97/23/EC. Materials processed include stainless steel, aluminium, steel and non-ferrous metals, and in waterjet cutting also plastics, composites, glass, tiles and wood. Surface treatments such as blasting, polishing, electropolishing, coating and galvanizing are carried out via partner companies. Urgent orders are produced in three-shift operation.
