About Mammut Werkzeugmaschinenfabrik
Mammut Werkzeugmaschinenfabrik GmbH from Langenzenn is a contract manufacturing business with over 100 years of tradition in the region. The company offers machining services such as milling, turning, planing, drilling, grinding/honing, sawing and broaching, as well as painting, sandblasting, steel construction/welded fabrication and assembly, including CNC machining of parts up to 1800 x 1800 mm. Another pillar is machine tool construction: the company overhauls machines partially or completely, manufactures spare parts for brands such as VDF Heidenreich & Harbeck, Martin, Weipert, Boehringer and Schaerer, trades in used lathes and builds special machines including trimming machines. In addition, a service for die casting machines is offered, e.g. shot chambers, clamping plates, centering adapters and machine column repairs made from heat-resistant materials. In the InnoCast funding project, the company is participating in the development of machine components for processing magnesium composite materials using the DirCom casting process. Materials machined include steel and cast iron.

Materials & Processes
Steel
Material for welded fabrications and painted steel structures, including CNC machining of large components.
Grey cast iron (cast)
Used e.g. for faceplates of lathes in the spare parts and overhaul business.
Heat-resistant materials
For high-precision machine components of die casting machines in contact with the melt, e.g. shot chambers.
Magnesium alloy AM50
Matrix alloy for cast parts in the InnoCast funding project (DirCom casting technology).
AM50 + boron carbide particles (15 vol.-% B4C F600)
Magnesium composite material for increased stiffness in lightweight construction, processed using the DirCom process.
DirCom (Direct Compounding)
Innovative die casting process for processing particle- and short-fiber-reinforced magnesium components.
