Conservation of valuable materials by a highly efficient forming system (CoVaForm)
Date du début: 1 janv. 2014, Date de fin: 29 févr. 2016,
In the forging industry the biggest part of production costs are material costs. Different processes are used to get the final shape. Some processes e. g. machining have a bad material utilization. To raise the competitiveness of SMEs, one approach is to improve the material utilization by decreasing scrap material (flash, chips). A possibility for a higher material utilization is cross wedge roll ...

Resource efficient forging process chain for complicated high duty parts (REFORCH)
Date du début: 1 oct. 2012, Date de fin: 30 sept. 2014,
Many high duty parts for the automotive sector are forging parts made of steel (e. g. crankshafts and connecting rods). In common forging processes for complicated high duty parts, especially crankshafts (each produced motor vehicle needs one), an excess on material (flash) is technically needed which results in a material utilization between 60 and 80 %. Together with energy the material costs ar ...

Development of a variable warm forging process chain (DeVaPro)
Date du début: 1 janv. 2009, Date de fin: 31 déc. 2010,
"The geometrical spectrum of current warm forging processes is limited concerning the mass distribution of the final work piece geometry. The more the mass distribution varies along the longitudinal axis, the more press operations are necessary, as the tool material can only withstand limited loads. Additional forming operations have a negative impact on the achievable tolerances. This is caused ...
