Forging Presses

Besides hammers, presses are another compressive force instruments, used in the closed-die forging manufacturing process. The material  is “squeezed” between two dies and deformed by the movement of the ram. The main deference between hammers and presses consists in the way how the ram moves. Hammers deform the workpiece through repetitive strokes - from two to several tens, according to the size of the hammer.

The activity of a closed-die forging press ram is typically characterised by:
- one stroke, in some cases 2, to fill the die
- a lower ram velocity:
     2 to 50 mm/sec for a hydraulic press
     200 to 300 mm/sec for a mechanical press
    500 to 600 mm/sec for a screw press: as its velocity is higher, the screw press is an intermediate tool between hammer and conventional   presses.

Thanks to the fact that the applied force can be measured and recorded, press forging ensures excellent traceability and repeatability of the production which is more difficult to achieve with drop forging hammers.

The different types of forging presses have different applications:

  • Hydraulic presses are used particularly for the manufacture of aluminium components, and heavy steel or titanium components. The biggest press in the world for closed-die forging has a nominal strength of 100 000 metric tons, in France - 65000 metric tons. 
  • Mechanical presses are used for large series production - usually 10 to 30 000 pieces per month. They are suitable to any material, bur are preferably assigned the manufacture of automotive or truck steel components.
  • Screw presses are used for medium series production.

 

Setforge works with hydraulic, mechanical and screw presses. All of them deliver an excellent degree of mechanical and orientation integrity.
