About AC-Tech Metall- & Blechtechnik
AC-TECH Metall- und Blechtechnik GmbH is a system manufacturer covering the full range of sheet metal processing – from cutting services and blanks to complex assemblies and complete metal facades. At the Salzbergen plant, aluminium, steel and stainless steel sheets as well as profiles are processed: laser cutting at 4000 watts on 3000 x 1500 mm, CNC punching up to 8 mm sheet thickness (facade sheets up to 6 m in length), CNC bending up to 6000 mm in length, roll bending up to 3000 mm in length, as well as welding (MIG, MAG, TIG, stud and spot welding) and surface finishing including a 10 m long paint booth. In addition, 2D and 3D engineering, assembly and a just-in-time delivery service are offered, specialising in medium series. Core markets are structural steel and metal construction, facade construction, mechanical engineering, switchgear cabinet technology, agricultural machinery, automotive supply and design/architecture; reference projects range from the University Hospital Hamburg-Eppendorf and BMW Welt to Volkswagen's IAA trade fair stand. The company, spun off in 2016 from the Metal and Sheet Metal Technology division of Tuchel Maschinenbau GmbH (founded in 1991), has its administrative headquarters in Recke; production is located in Salzbergen on a site of approx. 10,000 m².
