Abstract
A plastics material transformation plant (100) comprises a transformation machine (10) for the plastics material by means of moulding or extrusion, a feeding hopper (13) which is positioned upstream of the transformation machine and a metering device (1) which is arranged to add a liquid additive to the transformation machine. The metering device (1) comprises a container (4) in which the liquid additive is contained, a metering pump (5) which is connected to the container in order to take the liquid additive and to supply it to the transformation machine (10), and a thermo-regulation system of the liquid additive which is arranged to maintain the temperature of the liquid additive in a range of 2° C. more or 2° C. less than a predetermined temperature value.
