Abstract

PROCEDIMIENTO PARA FABRICAR UN BASTIDOR DE RAQUETAS PARA JUEGOS POR MOLDEO POR INYECCION DE MATERIALES TERMOPLASTICOS. COMPRENDE EL BASTIDOR UNA CABEZA Y UN EJE EN EL QUE AL MENOS LA CABEZA SE FORMA COLOCANDO UN NUCLEO FUSIBLE DENTRO DE UN MOLDE ADECUADO E INYECTANDO MATERIAL TERMOPLASTICO EN EL ESPACIO DEFINIDO ENTRE EL NUCLEO Y LAS PAREDES INTERNAS DEL MOLDE, TENIENDO EL NUCLEO UNA TEMPERATURA DE FUSION INFERIOR A LA TEMPERATURA DE INYECCION, PERMITIENDO QUE SE ENDUREZCA LA PIEZA MOLDEADA Y A CONTINUACION ELEVANDO LA TEMPERATURA A UNA CANTIDAD SUFICIENTE PARA FUNDIR EL NUCLEO, PERO INSUFICIENTE PARA FUNDIR O DEFORMAR LA PIEZA MOLDEADA. EL NUCLEO SE CONFORMA DE MANERA QUE TENGA UNA SERIE DE TETONES DE POSICIONAMIENTO QUE CHOCAN CONTRA LAS PAREDES INTERNAS DEL MOLDE Y MANTIENE EL NUCLEO EN LA POSICION DESEADA.
