A process for the hot moulding of articles made of thermoplastic material, comprising the steps of:
- heating at least one plate of thermoplastic material to a plasticizing temperature;
- compressing said heated plate between two moulding surfaces, set opposite one another, of a pair of half-moulds;
- and
- forming, by injection moulding, at least one component anchored to a surface of the plate, while the plate is being compressed between said moulding surfaces.
Equipment for hot moulding of articles made of thermoplastic material, comprising a first half-mould and a second half-mould which are free to move with respect to one another between an open position and a closed position and are provided with respective moulding surfaces designed to carry out hot moulding of at least one plate of thermoplastic material, at least one of said half-moulds comprising at least one injection-moulding seat communicating with the respective hot-moulding surface, at least one injection channel being provided for injecting plastic material inside said seat.
