Forging Rolls

In roll forging, two curved dies rotating in opposite directions "squeeze" the stock as it is pulled through the rolls, much like cloth through a wringer. The forging stock deforms under the force exerted by the rigid dies and machine frame to make a part whose shape is determined by the shape and contour of the dies. Since there is essentially only rolling contact between the forging and the dies, roll forging is an efficient method of producing large reductions in a cross sectional area at minimal loads. When used to produce pre-forms for conventional press or hammer forging, roll forging can provide several advantages in reducing energy and material costs.


  1. Increase die life, decrease machine loading and energy consumption by minimizing material deformation in subsequent forging operation. 
  2. Help to produce more uniform quality products.
  3. Reduce rejects and save material.
  4. Increase productivity.

In addition, roll forging does not require skilled operators or great manual effort. The operator merely grasps one end of the heated stock with tongs, and inserts it between the rolls at the "open" position. Die rotation rolls the stock toward the operator who repeats the operation for a specified number of passes.
