Procedure for the manufacture of balls for sports practices, consisting essentially of a mass of suitable plastic material, which is taken at the end of a tube that is then passed into a mold that reproduces the shape of the ball, preferably with the reliefs that externally present the currents of leather and with appropriate roughnesses to give the surface a slight roughness, after which and after closing that mold, the free end of the tube carrying the plastic mass is connected to an air injector under pressure, forcing said mass to adapt to the interior surface of the mold and take its shape, continuing said injection until reaching the internal pressure that the finished ball must have, then proceeding to throttle the plastic material under the support tube, closing in this way the ball that is then allowed to cool and can be demolded.
