Drop Forging vs Press Forging

Differences Between Drop Forging and Press Forging

Metal forging is the approach to manipulating metal into a particular design. This is frequently accomplished through one of 2 methods, drop forging and press forging.

Drop Forging – With drop forging (also known as hammer forging), the metallic billet is introduced into the die and hammered with numerous hits. This particular process goes on the billet is formed into form. Drop forging could be operated both at higher or even room temperatures, along with tongs are usually needed.

Throughout this procedure, the surface layers of the metal are changed into shape. Nevertheless, the middle part of the metal is going to stay fairly un deformed. Draft angles are usually used much more in this approach than with press forging. The original expense set in place is additionally under that of press forging, but production fees could be more pricey as volume increases.

Press Forging – Press forging uses a continuous and slower stress to shape metal into a particular design. Thus, rather than utilizing several hammer blows to adjust the billet, this particular strategy relies on a singular compression. Like hammer forging, press forging may additionally be accomplished at low or high temperatures.

With press forging, the metal is formed in a consistent way from the counter on the middle. This means the images created are cleaned as well as the end result is typically better. Tongs are generally not necessary, and draft angles aren’t as often used. First setup expenses can also be greater with press forging, though the technique becomes cheaper as volume increases.
Disadvantages and advantages

Pros of Hammer Forging

  • Lower first setup costs
  • Faster process

Cons of Hammer Forging

  • Only shapes the surface area of the workpiece
  • Strain rate even more hard to control

Pros of Press Forging

  • Cheaper for increased volume runs
  • Deforms the entire workpiece (not simply the surface)
  • Strain rate may be managed easier

Cons of Press Forging

  • Higher setup costs
  • More time consuming process
