ABSTRACT:
This invention concerns an injection moulding process for soles in expansible and cross-linking "EVA" based compounds characterised in that during the cooling stage of the moulded sole the spontaneous shrinkage of the same is arrested by means of a template consisting of a rigid shaped plate placed on the sole so that its edge connects with a perimeter edge realised specifically on the upper surface of the sole, whose dimensions reduce no further either during the remaining cooling phase of after cooling.
