Abstract
Method for processing plastics material, comprising the following steps: feeding the plastics material into a screw machine by means of a feeding device; plasticizing the fed plastics material by means of the screw machine to form a polymer melt; and processing the polymer melt by means of the screw machine, wherein the viscosity of the polymer melt is set by means of the screw speed of the screw machine, and device for processing plastics material.
Claims15
A method for processing plastics material, comprising the following steps:
- feeding the plastics material into a screw machine by means of a feeding device;
- plasticizing the fed plastics material by means of the screw machine to form a polymer melt;
- and
- processing the polymer melt by means of the screw machine, wherein a viscosity of the polymer melt is set by means of a screw speed of the screw machine.
A device for processing plastics material, comprising a screw machine, in particular a multi-shaft screw machine, comprising
- at least one feed opening for feeding the plastics material into the screw machine;
- and
- at least one treatment element shaft for plasticizing the fed plastics material into a polymer melt and for processing the polymer melt,
- wherein the device and/or screw machine is designed to set a viscosity and/or a melt flow index of the polymer melt by means of a screw speed of the screw machine.
