Title (EN) LOCALIZED HEAT TREATMENT
(FR) TRAITEMENT THERMIQUE LOCALISÉ
Abstract:
(EN) Embodiments are described herein of a bifurcated heat treatment apparatus and methods for localized heat treatment of a golf club hosel or golf club head. The heat treating method comprises a bifurcated process in which the golf club head is treated in the first heating unit via induction heating and then moved to the second heating unit for convection heating. Both steps are to localize the hosel heat treatment. The heat treatment apparatus may also include a cooling component, such as a heat sink, to ensure the body of the club head remains at the correct temperature during the second heating stage when the hosel is heated in isolation. The overall bifurcated method and apparatus of the localized heat treatment leads to a hosel or golf club head with at least two different hardness values to allow for manipulation of the material without cracking or fracturing.
(FR) Des modes de réalisation de l'invention concernent un appareil de traitement thermique à bifurcation et des procédés de traitement thermique localisé d'un col de club de golf ou d'une tête de club de golf. Le procédé de traitement thermique comprend un processus à bifurcation dans lequel la tête de club de golf est traitée dans la première unité de chauffage par induction puis déplacée jusqu'à la deuxième unité de chauffage pour un chauffage par convection. Les deux étapes servent à localiser le traitement thermique du col. L'appareil de traitement thermique peut aussi comprendre un composant de refroidissement, tel qu'un dissipateur thermique, pour assurer que le corps de la tête de club reste à la température correcte pendant la deuxième étape de chauffage lorsque seul le col est chauffé. Le procédé et l'appareil globaux à bifurcation de traitement thermique localisé produit un col ou une tête de club de golf avec au moins deux valeurs de dureté différentes afin de permettre la manipulation du matériau sans produire de fissures ou de fractures.
