Abstract

SE PRESENTA UN METODO Y UN APARATO PARA MOLDEAR A INYECCION UNA ALEACCION DE METAL EN EL CUAL LA ALEACCION SE MANTIENE EN UN ESTADO SEMISOLIDO DIXOTROPICO EN UN COMPRESOR RECIPROCO (16) A TEMPERATURAS POR ENCIMA DE SU TEMPERATURA SOLIDA Y POR DEBAJO DE SU TEMPERATURA LIQUIDA Y LUEGO SE INYECTA COMO UNA PASTA DIXOTROPICA AL INTERIOR DE UN MOLDE (22) PARA FORMAR UN PRODUCTO UTIL. DESPUES DE LA FINALIZACION DEL MOLDEADO A INYECCION, LA BOQUILLA (20) DEL COMPRESOR SE SELLA MEDIANTE LA SOLIDIFICACION DE UNA PARTE DEL RESIDUO DE LA ALEACCION QUE PERMANECE EN LA BOQUILLA.
