Stamped electrodes

Electrodes and special CAPS stamping

We have the necessary technology for electrodes and special CAPS stamping (deforming without material loss). By means of the material deformation using dies (cold forming) we can make the most of the material: The material saving allow us to reduce the cost of the piece and, consequently, brings down its sales price. The bigger the series is the grater the saving.

Cold forming 90º

90º Cold formed

In DEM we are able to bend the copper (Cu) bar/rod up to 90º with a minimum radius; this cold forming is the result of the application of our own technique developed by our Engineering Team - that is not based on the classic process of bending; the result is the large part that appears on the photo. Previously, this type of pieces could only be made from plate or casting. Which are the advantages of cold forming resistance welding consumables requiring a 90º angle? When working the bar material with this technique, we achieve a homogeneous continuity in the material fibres along the whole piece. The cold forming also allows us to replace the shank adapters that are welded to the end of the arms. The result is a single piece. With the conventional bending process there is a need to weld the two pieces together. With the cold forming process, we eliminate the risk of leaks from...
