Estimating the term…
An injection unit for a moulding machine includes an injection cylinder, and an injection piston is provided in the injection cylinder. During an injection process, the injection piston is configured to push out a plasticized mass—in particular plasticized plastic—from the injection cylinder and to feed it to a moulding tool via an injection nozzle. At least two plasticizing units and two supply channels are provided, and the at least two plasticizing units can be fluidically connected with the injection nozzle by the supply channels. The at least two plasticizing units are configured to supply the injection cylinder with the plasticized mass via the supply channels and the injection nozzle prior to the injection process.
