Fields of activity

Fundamentals in Metal Forming:

  • Process simulation and analysis: various methods of computational determination of process parameters during forming process 
  • Fundamentals in Material Investigation: evaluation of the elastic-plastic behaviour of metals, influence of forming process related parameters on properties of workpiece
  • Fundamentals of tribology in metal forming processes: effects of friction on process development, techniques and standards for evaluation of mechanisms of friction, lubrication and wear for sheet and bulk metal processes.

Scope of Metal Forming Techniques:

  • Sheet metal forming: deep and stretch drawing of carbody parts and general purpose flat shaped parts, bending, superplastic forming of sheets and tubes, hydro-/ heatforming of sheets, tubes and profiles made of steel, aluminium and magnesium alloys.
  • Bulk metal forming: hot and cold extrusion, forging applications, upsetting and lateral extrusion, multiaxis process development for bulk metal forming; ultrasonic assisted wire and tube drawing, piezo applications; semi-solid forming of lightweight alloys and high melting biocompatible materials.

Tooling/Tool development:

FEA based process design and development of suitable tool concepts, Computer Aided Design (CAD) of dies and tools for sheet and bulk metal forming, wire drawing and thixoforging, stress and strain analysis of tool components, tool material and coating investigations, tool and die manufacturing (own die shop), prototype tooling for bulk and sheet metal forming.

Press machines / metal forming equipment:

Laboratory equipped with various sheet metal press machines for deep drawing, trimming and re-striking; clamping devices for heet and hydroforming applications up to capacity of 35,000 kN; conceptual optimization of drawing cushion systems; development/concepts of energy recovery during deep drawing process; research activities on behaviour servo-electrically driven press machines.
