Abstract

An upsetting method for working a metal slug of cylindrical shape and provided with a coating is disclosed. The slug is placed, lengthwise, in a sleeve the internal wall of which leaves a space with respect to the lateral surface of the slug, the slug and sleeve assembly is placed in an upsetting container, and an upsetting force is exerted on the slug on at least one of its transverse surfaces until a determined slenderness ratio has been obtained, and the slug is separated from the sleeve. The slug is upset continuously but only the slug is upset because of the space formed by the internal wall of the sleeve. The material of the sleeve, for example made of steel, is not welded or seized to the slug, which means that it need not be machined in order to separate the two after the operation.
