A nozzle unit for a reaction molding machine, comprising an inlet channel prepared for connection to a mixing head outlet and comprising a first dispensing nozzle, which is prepared for applying a reactive mixture and which is connected to the inlet channel in a first operating state, a second dispensing nozzle being present, which is connected to the inlet channel in a second operating state and which is likewise prepared for applying a reactive mixture. Further disclosed is a mixing head device for a reaction molding machine having the nozzle unit, to a reaction molding machine having the mixing head device, and to a method for producing a plastic part.

Nozzle unit for a reaction moulding machine and method for producing a plastic part

A device and a method for producing reaction plastics, including a first metering device with a first metering unit and a second metering unit, each of which is suitable for receiving and dispensing a first mixing component in a metered manner, a second metering device which is suitable for receiving and dispensing a second mixing component in a metered manner, and a mixing device which is suitable for receiving and mixing the first mixing component dispensed by the first metering unit and/or the second metering unit of the first metering device and the second mixing component dispensed by the second metering device. For this purpose the first metering unit and the second metering unit are connected to the mixing device such that prior to beginning the mixing process, the first mixing component can be brought to an operating state required for the mixing process, in particular an operating pressure, by guiding the first mixing component from the first metering unit to the second metering unit via the mixing device.
