Abstract: The present invention relates to a process for the recovery of metals and coatings present on the metals from composite materials by means of the treatment of the composite materials with specific solvents at elevated temperatures, whereby the coating is dissolved and recovered from this solution while the metal is quantitatively separated from the solution in a pure state, after which it can be recycled.

Abstract: The mould of the mould arrangement comprises a bottom plate and two side portions which are movable to a first position in which they engage one another and the bottom plate to define a mould cavity and to a separated position. The side portions define cooling passages having entrances in bottom surfaces of the side portions and the bottom plate has at least one plenum chamber formed therein which has exits which, when the side portions are in their first position, communicate with cooling passage entrances so that air blown into the plenum chamber passes through the cooling passages. A bottom plate for the arrangement is also disclosed.
