Abstract
SE DESCRIBE UN PROCESO Y APARATO PARA MOLDEADO POR SOPLADO DE RESINAS TERMOPLASTICAS, PARTICULARMENTE CUERPOS HUECOS, Y QUE CONSISTE EN LLEVAR A CABO, EN UN PRIMER PASO, UNA INYECCION DE RESINA EN ESTADO TERMOPLASTICO EN UN PRIMER MOLDE CALEFACTOR FORMADO POR CAVIDADES TABULARES ESTRECHAS QUE TIENEN UNA ZONA SUPERFICIAL, DESDE DONDE, UNA VEZ QUE LA RESINA HA ALCANZADO EL ESTADO TERMOELASTICO, ES EXTRUDE EN UN SEGUNDO PASO PARA FORMAR UN HUECO ORIENTADO EN UN SEGUNDO MOLDE DONDE, EN UN TERCER PASO, SE COMPLETA EL MOLDEO MEDIANTE SOPLADO, HASTA QUE SE OBTIENE EL CUERPO FINAL HUECO. SE DESCRIBE UN APARATO QUE PUEDE REALIZAR UN GRUPO DE CUATRO PRE-MOLDEOS, SITUADO EN UN PLANO SUPERIOR, MONTADO SOBRE UN FILM Y CON POSIBILIDAD DE ROTACION DE 90 ORES EN FRENTE DE LOS MODULOS DE PRE-MOLDEO, EN PARES. EL PROCESO Y APARATO SE PUEDEN APLICAR EN LA INDUSTRIA DE RECIPIENTES, QUE REQUIERE UNAS PAREDES MUY REGULARES EN TODO EL RECIPIENTE.
