Method and device for the manufacture of moulds and granulate

摘要

The method involves providing sand and plastic i.e. plastic granulate, and heating the sand in a rotary furnace (4) that circulates the sand. Portions of the heated sand and the plastic are filled in flow mixers (9, 13, 16). The portions of the heated sand and the plastic are mixed to form a mold mass. A portion of the mold mass from the mixers is output into a mold device. Other portions of the heated sand and the plastic are filled in the mixers and mixed. The mold mass present in the mold device is cooled and solidified to form a molded part. The molded part is removed from the mold device. Independent claims are also included for the following: (1) a method for manufacturing a granulate for subsequent processing of a molded part (2) a device for manufacturing a molded part or a granulate.
