Abstract
An extrusion system for producing molded parts from plastics has an extruder with an input part for receiving, melting and working plastic material, a multi-screw extruder connected to the extruder input part, and an extruder output for outputting the melt. A material supply is connected to the input part, for solid, liquid and/or gaseous raw materials or additives, and a motor drives the extruder. A vacuum system, is connected at least to the multi-screw extruder, and a measurement device and a downstream extrusion die are provided on the extruder output part. A controller receives measurement signals from the measurement device and controls the individual components of the extrusion system.
Claims20
An extrusion system for producing molded parts from plastics, comprising:
- an extruder (1) for obtaining plastic melts, which has an extruder input part (4) for receiving, melting and working plastic material, a multi-screw extruder part (5), which is connected to the extruder input part (4), and an extruder output part (6) for outputting the melt;
- a material supply (3), which is assigned to the extruder input part (4), for solid, liquid and/or gaseous raw materials or additives;
- a motor (10) for driving the extruder (1) in a rotary manner;
- a heater (11);
- a vacuum system (12), which is assigned at least to the multi-screw extruder (5),
- a measurement device (8) and a downstream extrusion die (2) on the extruder output part (6), and
- an installation control unit (9) for receiving measurement signals of the measurement device (8) and controlling the individual components of the extrusion system (1 to 15) and configured such that dose and/or fill level and/or dwell time and/or extruder rotation speed and/or vacuum can be regulated and set by means of the material supply (3) and/or the motor (10) and/or the vacuum system (12) in such a manner that the respective molded parts to be created have optimal properties in respect of the demands made of them.
