Title
(EN) INJECTION MOLDING BALATA GOLF BALL COVERS
(FR) MOULAGE PAR INJECTION D'ENVELOPPES EXTERIEURES DE BALLES DE GOLF EN BALATA
Abstract
(EN)
A method for manufacturing hemispherical shells for covering a golf ball core, which comprises: mixing a quantity of balata sufficient to form a desired number of hemispherical shells configured and adapted for covering golf ball cores; transferring a predetermined quantity of the mixed balata to an extruder and extruding a plurality of strands of the balata at a temperature of between about 140° and 280 °F; cutting the strands into pellets of a desired size and injection molding the pellets into a hemispherical shell.
(FR)
La présente invention concerne un procédé de fabrication de coquilles hémisphériques servant à recouvrir la partie centrale d'une balle de golf. Ce procédé comprend: le malaxage d'une quantité de balata suffisante pour donner le nombre désiré de coquilles hémisphériques d'une forme et d'une conception convenables pour qu'elles recouvrent des parties centrales de balles de golf; le transfert d'une quantité déterminée du balata ainsi malaxé à une extrudeuse, et l'extrusion de plusieurs boudins de balata à une température comprise entre environ 140 et 280 °F; le découpage des boudins en pastilles de la taille désirée et le moulage par injection des pastilles pour former une coquille hémisphérique.
