Upset Forging...

Upset Forging is the term used to describe the gathering of metal over a given area and then subsequently formed in dies (or tools) to a required shape. Conventional methods of upsetting are electrical resistance and mechanical pre-forming. The upset forging process can be carried out at the end of the bar, both ends of the bar, or at any mid-division point.

Typical examples of upset forged components are eyebolts, hex /square head bolts, torsion bars, anti-roll bars and connecting rods (clevises).

· Inherent strength retained by containing metal grain flow.
· No stress areas created where material size needs to be reduced, which would occur if bar turned.
· No brittleness or porosity concerns with forgings (sometimes prevalent in the casting process)
· No concern of fractures at weld joints (as could occur on fabrications)

We have vertical crank, hydraulic and screw presses capable of forging from 10mm diameter up to 100mm diameter and horizontal machines with a working capacity from 6mm diameter up to 80mm diameter x 6m long. Material specifications range from mild, carbon, alloy, though to stainless steel grades.

At our manufacturing facility in Lye, West Midlands, we have installed several Horizontal forging lines. The walking beam transfer unit makes the use of several compressed air cylinders to transfer the work piece from one die to the next and is easily capable of increasing output by up to 3 times that of conventional manual operation.
