Flow cell with sonotrode for influencing static and flowing plastic melts

摘要

Universal flow cell with sonotrode (1) for influencing static and flowing plastic melts for extruders or injection molding machines with a housing (3) and a sonotrode flange (12) and a doser (4), characterized the sonotrode (1) is connected to the sonotrode flange (12) via a receiving body (2) or directly to the housing (3), in the receiving body (2) or in the housing (3) a first sleeve (5) is arranged, which extends into the housing (3), the first sleeve (5) is guided in the housing (3) by means of an enclosing second sleeve (6), between the sonotrode flange (12) and receiving body (2) or between sonotrode flange (12) and housing (3) and the first sleeve (5) arranged inside a metal seal (7) is provided, which ensures the melt-sealing, the sonotrode end surface (16) engages in a space between the melt channels (10.1 and 10.2), the melt volume in the space between the melt channels (10.1 and 10.2) in front of the sonotrode end face (16) is made changeable by a structural design of the metering device (4).
