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.

Injection moulding process for soles in expansible and cross-linking 'Eva'

An injection molding process for soles using expansible and cross-linking EVA based compounds. During the cooling stage of the molded sole, the spontaneous shrinkage of the molded sole is arrested by means of a template placed on the sole. To accomplish this, a series of perimeter pin elements extend from the bottom surface of the template and are coupled with a corresponding series of perimeter holes defined on the upper surface of the sole. The dimensions of the sole therefore will reduce no further either during the remaining cooling phase or after cooling.

Injection moulding process for soles in expansible and cross-linking 'EVA'

This invention concerns an injection molding process for soles having a colored treading surface produced with expansible and cross-linking 'EVA' compounds involving the use of colored inserts molded with the same molding material used for sole, but of a different color, fed into cups on the bottom of the mold impression and shut by caps also molded in the same material used to mold the soles.
