Forging Means Uncompromised Strength

Drop Forging

Closed die drop forging is a steel shaping process whereby a heated steel billet is placed on a lower die mould block, while an overhead, die-equipped ram hammer drives or “drops” down, forcing the metal to fill the contours of the two die blocks. Forging on a drop hammer is carried out in a succession of die impressions using repeated blows. The quality of the forging, and the economy and productivity of the hammer process depend upon the tooling and the skill of the operator.

Upset Forging

Upset forging is a manufacturing process that plastically deforms metal under great pressure into high strength components of varying sizes. This forging process is ideal for longer shapes where only one end of a part needs to be forged. Upset forgings are made by gathering material to a designated area of a carbon, alloy, or stainless steel bar. The mechanical press used to manufacture these components operates on a horizontal plane. The dies are split to allow material to protrude beyond the mechanical press, and some of the forming force is provided by a third die attached to the header.

Why Forge?

The forging process can create parts that are stronger than those manufactured by any other metalworking process. This is why forgings are almost always used where reliability and human safety are critical.
