Forging / Hammering

The die segments (2, 3 or 4-die configuration) performing a continuous hammering action on a rotating work piece. The dies are formed to the shape to be formed on the workpiece. Depending on the grade of deformation the process will be cold or hot.

The forging technology can be used for steel, aluminum , copper, titanium and various other metal material.

Performance data

The performing force is adapted individually to the work piece resp. to the forming tools. The force of the machine s can be between 600 kN up to 6000 kN.

The combination from electrical, servo-hydraulical and pneumatical drive system and control system is basis for optimum results in quality and repeatability of the work pieces.

Depending on the required capacity we provide various handling systems, customized to the application. As well a simultaneous double-end forming of longer parts is possible. Please ask for more deails.

 

Applications

The forging technology is used for diverse applications.

Automobile industries:

  • trailer axles
  • rear axle tubes
  • drive shafts
  • rear axle stabilizers
  • cylinder sleeve
  • bumper mounting
  • cardan shaft
  • steering column
  • exhaust pipes
  • shock absorber tubes
  • camshafts etc.

Generic applications:

  • light poles
  • balusters
  • pressure bottles
  • furniture tubes

Since now we realized forged parts with pipe diameters between 12 mm - 600 mm.

Advantages of forging / hammering

  • Weight optimization: Forging / Hammering enables a targeted distribution of the wall thickness at weight-critical components e.g. for automobile components. Using the forging / hammering technology, parts could be changed from solid to hollow material in many cases.
  • Material savings: Using forging operations with the related material displacementcomponents can be formed to the desired form without material losses. The material input can be reduced destinctively.
  • Safety: Forged / hammered components are distinguished with a homogeneous fibre flow. Differing to machined shapes the forged / hammered components are characterized by higher strength.
  • Reduction of single components: Work pieces, which used to be made of multiple single components and then welded, can be forged of wrought products. Beside of the better material properties, forging / hammering generates also cost savings on storage of single components.

    With our know how we are at your disposal to develop new production concepts based on GFU forging / hammering technologies. We support you from the process related part optimization, over designing of the machine concept until the delivery of turn-key production lines.
