Method and device for mixing and supplying plastic into a mold for a vacuum infusion

A device for mixing plastic from liquid components in a mixer and conveying the plastic through a line into a mould, in particular for vacuum infusion, at a pressure below ambient pressure or below another specific pressure that should not be exceeded in the mould, the device comprising:

• at least one pump that is configured to pump the components from a respective component container into a mixer that is configured to mix the components,
• a controller that is configured to control volume flows in such a manner that the components are supplied to the mixer in a specific ratio,
• a device that is configured to input and/or measure pressure loss in the line between a pressure sensor in a component supply line leading to the mixer and the mould, and
• a controller that is configured to control, taking into consideration the determined pressure loss, the volume flow in the component supply line of the pressure sensor such that the component is supplied to the pressure sensor and from the pressure sensor to the mixer at a pressure measured by the pressure sensor that is greater than the ambient pressure or another specific pressure that should not be exceeded in the mould by at most the pressure loss.
