Abstract

Product forming system, e.g. by a rotational moulding process, comprising an electrically heated mould of which at least one mould part is provided with a plurality of electrical resistors for heating a cavity inside the mould, means for applying electric current to the electrical resistors, and a measurement device for measuring the electric current flowing through the electric resistors. The measurement device comprises a plurality of openings, with at least one electrical conductor running through each opening, each of which is connected in series to at least one of the electrical resistors. At each opening, an inductive element is provided for measuring the electric current through the respective at least one electrical conductor. The mea- surement device comprises electronic components for converting the measured currents into measurement data and for storing and/or transmitting the measurement data.
