  • Patent number: 11241737
    Abstract: Manufacturing a hard-metal pressed article includes providing a multi-part die, feeding at least one frontal mold part, feeding at least one transverse mold and locking the at least one frontal mold part and the at least one transverse mold part to define a cavity for the article. Feed directions of the at least one frontal mold part and the at least one transverse mold part are inclined. The at least one frontal mold part and the at least one transverse mold part define surfaces of the article. The resulting cavity includes at least one opening through which a punch is insertable. Next, a filling shoe is fed above an opening of the cavity and fills the cavity with a powder, and the powder is compressed with at least one punch. The feeding of the transverse mold part takes place along a feed direction that is parallel to the main pressing direction.
