Abstract:
Manufacturing hard-metal pressed articles includes providing a multi-part die comprising a plurality of lateral mold parts defining lateral surfaces of a cavity for the article. At least one of the plurality of lateral mold parts defines a portion of an upper side of the cavity. The lateral mold parts and at least two lateral punch parts are fed. At least two of the plurality of lateral mold parts are provided with a guide recess for one of the at least two lateral punch parts. A filling unit feeds an opening of the cavity which is filled with a hard-metal powder. At least one upper mold part is fed, which defines a portion of the upper side of the cavity. The lateral mold parts and the upper mold part are held to form the cavity. The powder is compressed with at least two lateral punch parts and the part demolded.
