About B&M Maschinenbau
B&M Maschinenbau GmbH was founded in 2012 in Hanover as B(aum) and M(üller) Maschinenbau GmbH by Oliver Baum and Siegfried Müller and specializes in custom fabrication, prototype construction and sustainable product development in mechanical engineering. The portfolio of services includes CAD design, FEM calculations, generative design, 3D scanning by photogrammetry, CNC machining, steel and metal construction, welded assemblies, control system engineering, assembly as well as painting and powder coating. In the field of additive manufacturing, the company works with numerous processes such as SLS, FDM, SLM, MJF, SLA, CJP, MJM, DPP and binder jetting and produces components from plastics and aluminium and steel casting alloys. As the inventor of internal pipe bending (IPB) technology, the company developed the world's first functional internal pipe bending machines for large-diameter pipes up to DN800/1100 together with isobend GmbH; today the technology is offered by the subsidiary Bendforce GmbH in Celle. Customers include isobend GmbH, Hamburger Energiewerke, Enercity and BlueEyesBaits. The location is at Nedderfeldstraße 4 in Hanover.
