Blech mit System – Contract manufacturer for enclosure technology
B&S Blech mit System is a family business founded in 2004 and based in Grafenau (Lower Bavaria) that designs and manufactures enclosures, components and assemblies from sheet metal for industrial applications. The manufacturing range covers the complete spectrum of sheet metal working: laser cutting, punching, bending, milling, turning, welding, deburring as well as powder coating, screen printing and laser marking. Steel, galvanized steel, stainless steel and aluminium are processed in sheet thicknesses up to 15 mm, from prototype through small series to large-scale production. In addition, the company offers a design service with CAD design, FE simulation and reverse engineering as well as pre-assembly through final assembly of complete assemblies. The service portfolio primarily serves medical technology, vending machine technology, the automotive industry (charging stations) and industrial enclosure technology; production is spread across three plants in Grafenau and one plant in the Czech Republic.
