Abstract

Un método de fabricar un marco para una raqueta para juegos, comprendiendo el marco una cabeza y una caña, por moldeo de un material termoplástico, caracterizado porque al menos la cabeza se forma inyectando el material termoplástico, caracterizado porque al menos la cabeza se forma inyectando el material termoplástico en torno a un macho fusible, teniendo el macho un punto de fusión por debajo de la temperatura de inyección y estando configurado de manera que proporcione unos medios de soporte internos entre la pared de la pieza moldeada que ha de quedar en la circunferencia exterior de la cabeza y la pared de la pieza moldeada que ha de quedar en la circunferencia interior de la cabeza, permitiendo que se endurezca la pieza moldeada y subiendo luego la temperatura hasta un valor suficiente para fundir el macho, pero insuficiente para fundir o deformar la pieza moldeada.
