Abstract

SE PRESENTA UN PROCESO MEJORADO PARA UN MOLDEADO A INYECCION POR ESTIRAMIENTO POR SOPLADO. EN EL PROCESO, UNA RESINA FUNDIDA ES INYECTADA A UNA CAVIDAD DE INYECCION DEFINIDA POR UN MOLDE DE INYECCION, UN MOLDE DE LABIO Y UN NUCLEO DE INYECCION PARA FORMAR UNA PROFORMA DESEADA EN DONDE EL TIEMPO DE ENFRIAMIENTO PARA ESTA PROFORMA SE REDUCE POSITIVAMENTE PARA FORMAR UNA CAPA SUPERFICIAL RIGIDA SOBRE LA SUPERFICIE EXTERIOR DE LA PROFORMA SIN INCREMENTAR EL GROSOR. DESPUES DE ESTO LA PROFORMA SE LIBERA DEL MOLDE DE INYECCION Y SE TRANSFIERE A UN MOLDE DE SOPLADO CON UNA PARTE DE BOQUILLA QUE SE SUJETA CON EL MOLDE DE LABIO MIENTRAS LA CAPA SUPERFICIAL MANTIENE LA CONFIGURACION DE LA PROFORMA Y EL INTERIOR ESTA EN UN ESTADO DE ALTA TEMPERATURA, Y SE MOLDEA POR ESTIRAMIENTO POR SOPLADO EN UN ARTICULO HUECO MOLDEADO, POR EJEMPLO UNA BOTELLA, CUYA MAYOR PARTE ES ULTRAFINA EN EL MOMENTO CUANDO UNA TEMPERATURA SUPERFICIAL DE LA PROFORMA QUE SE ELEVA DEBIDO A SU PROPIA TEMPERATURA INTERIOR ES SIGNIFICATIVAMENTE MAYOR QUE LA TEMPERATURA DE TRANSICION A CRISTAL (TG) Y SE ESPERA QUE ALCANCE UNA TEMPERATURA PICO. DE ESTA FORMA, ES POSIBLE PERMITIR UN MOLDEADO DE UN ARTICULO HUECO QUE TENGA UN GROSOR DE 0.17 MM O MENOR SIN ESTAR AFECTADO POR LAS LIMITACIONES DEL GROSOR DE LA PROFORMA Y LA TEMPERATURA DE MOLDEADO INCLUSO EN UN PROCESO DE MOLDEADO EN EL QUE LA PROFORMA SE LIBERA DEL MOLDE A ALTA TEMPERATURA Y SE EXPONE POSTERIORMENTE DE FORMA INMEDIATA A UN MOLDEADO POR ESTIRAMIENTO POR SOPLADO.
