With the punching technology, the esw GROUP brings together the competences of cold forming and stamping.
Punching involves the processing of blanks and preforms that have previously been produced from wire or sheet metal coil. This also allows us to offer extruded components with a very small length to diameter ratio. Technologically, this results in very high dimensional and surface accuracies. We manufacture on toggle presses with press forces of up to 800 t and use progressive and transfer tools that are designed and manufactured in-house.
