Abstract

The present invention concerns an injection moulding process for making an item without welds (1; 10) having at least two elements (1a, 1b; 10a, 10b) physically separated from each other, interconnected by means of two connection portions (2a, 2b; 12a, 12b) mutually interpenetrating and non-removable with respect to each other. Said process comprises the use of at least a first mould (100; 110) shaped to define with its own injection chamber (101) the volume corresponding to one of the two connection portions (2b; 12b), separating it with its own walls from the other connection portion (2a; 12a). Said first mould (100; 110) is made of a support material soluble in a solvent bath (400). The injection moulding provides for injecting at least into the injection chamber (101) of said first mould (100; 110) an injection material which is injectable at a temperature lower than the decomposition temperature of the material with which the first mould is made.
