Abstract

A method of manufacturing compacts and an arrangement for manufacturing compacts, in which the disadvantages of the state of the art are overcome and an efficient method and at the same time a simple construction and a simple implementation are achieved. This involves a method for manufacturing compacts, wherein after feeding the feedstock, pre-pressing into a pre-agglomerate using at least one pre-pressing punch or at least one stuffing screw and subsequently main pressing of the pre-agglomerate into a compact in at least one pressing die using at least one main pressing punch and subsequently ejection of the compact from the at least one pressing die are performed, pre-pressing, main pressing and ejection being performed in a mutually parallel working direction. This also involves an arrangement for manufacturing compacts, wherein at least one pressing die is provided in die tool receptacle with a feed for feedstock.
