Device for mixing at least two chemically reactive plastics components under pressure, having a mixing chamber, into which the plastics components are injected in each case by way of a component-feeding opening, wherein a reversible control piston is provided for opening and closing the component-feeding openings and for discharging plastics mixture remaining within the mixing chamber, wherein the control piston is connected to an electric drive. Alternatively, in the case of a transfer mixing head, the cleaning piston may be coupled to an electric drive. A method for operating such a mixing head is also disclosed.
A device for mixing at least two chemically reactive plastics components under pressure, having a mixing chamber, into which the plastics components are injected in each case by way of a component-feeding opening, wherein a reversible control piston is provided for opening and closing the component-feeding openings and for discharging plastics mixture remaining within the mixing chamber, characterized in that the control piston is mechanically connected to an electric drive, wherein a movement of the electric drive brings about a linear movement of the control piston.
A device for mixing at least two chemically reactive plastics components under pressure, with a mixing chamber into which the plastics components are injected via respectively a component-feeding opening, wherein a reversible control piston is arranged for opening and closing the component-feeding openings and for discharging plastics mixture remaining within the mixing chamber, wherein the device is configured as a transfer mixing head and has a cleaning piston, wherein an outlet chamber adjoins the mixing chamber, and in the outlet chamber the cleaning piston is reversibly arranged for discharging the reactive plastics mixture from the outlet chamber,
A method for mixing at least two chemically reactive plastics components under pressure, wherein a reversible control piston is arranged in a cylindrical mixing chamber, into which the plastics components are injected via respectively a component-feeding opening, for opening and closing the component-feeding openings and for discharging plastics mixture remaining within the mixing chamber,
