Abstract
The invention concerns a compounder-injection-molding unit, wherein a continuously operating compounder is coupled to a discontinuously operating screw injection-molding machine.
Claims7
A compounder-injection-molding unit comprising a compounder (1), especially a twin-screw extruder, for producing a materially and thermally homogeneous compound melt of at least one plastic material and further additives;
- and a screw-type injection molding machine (2) with a standard feed zone (6),
- characterized in that
- the exit of the compounder (1) is directly connected with the standard feed zone (6) of the screw-type injection molding machine (2) through a connecting unit (8) without counter-pressure from the screw-type injection molding machine (2),
- said injection molding machine (2) has a feed space as a reservoir (10) for a compound continuously produced by the compounder (1);
- a conveying screw (5) positioned within the screw-type injection molding machine (2);
- and
- said injection molding machine (2) has a sensor (7) for measuring the filling level of the injection molding machine (2) and controlling the operation of compounder (1).
