Abstract:
The invention comprises, a first preliminary step of cleaning the treatment surface of the moulding base tool and a second step in which the necessary layers of mould-release agent are applied to the treatment surface of the moulding base tool. Based on said preliminary steps, the process is characterized in that, in a later step, the treatment surface (1), covered with a mould-release agent (3), is provided with a continuous uniform film (4) of resin having a low concentration of volatile elements and a laminar resin supporting a very high mould-release capability, which facilitates the transfer of resin to the treatment surface (1) of the moulding base tool (2).
