what is electic upsetting

What is electric upsetting?

This process allows the ends of bars to be thickened without damaging the material. The material structure is fully retained. Optimal strength is achieved in this way. There are 2 different types of electric upsetting:

Closed-die upsetting as a precision forging process. Ends can be provided with thickening in the order of +/- 0.2 mm in this way.

Open upsetting is used for thickening bars intended for subsequent cutting machining



 

When is electric upsetting used?
This is the most economical solution when thickening is applied to relatively long bars.

Which components are suitable for electric upsetting?
Torsion bar springs, hook bolts, long drive shafts, etc.

Which materials can be processed?
All ferrous metals can be processed.

What advantages does electric upsetting offer?
In the case of long bars, where only a single end or both sides need to be thickened to accept dive camx, squares, splines, etc., considerable economies in material and turning are possible. Thanks to an optimal fibre flow in the material, electrically upset components are able to withstand very high loadings.
