ABSTRACT:
This invention relates to automating a process for manufacturing articles from plastic, particularly recyclable plastic waste. A lengthened separator head is flanged to a plasticizer to supply melting serially to several molds, by way of mold inlet shut-off mechanism. A preprogrammed control device monitors the filling of a respective mold by way of a pressure sensor in the mold. When the desired filling of the mold has occurred, the inlet shut-off mechanism is closed by the control device and another mold that is ready to be filled is filled with melting by the opening of the corresponding inlet shut-off mechanism at the another mold. In addition, the control device controls the locking and tightening of the mold as well as its opening and emptying.
