Abstract
Process for the manufacture of balls, characterized essentially by subjecting a spherical core, of a material of small specific weight and slightly elastic, to an overmolding operation in a mass of thermosetting synthetic resin, under a pressure chosen from according to the desired tenacity in the finished ball, subjecting the assembly, while maintaining the pressure, to heating up to the curing temperature of the material or slightly higher, which is maintained for the time necessary for the heat to reach the layers internal of said material, so that it is hardened in a pre-stressed state around the bore.
