Abstract
EL CAMPO TECNICO DE LA INVENCION SON LAS MAQUINAS DE MOLDEADO, PARTICULARMENTE LA PARTE INTERNA (VARILLA DEL NUCLEO) DE DICHAS MAQUINAS DE MOLDEADO PARA MANUFACTURAR PROFORMAS TERMOPLASTICAS, QUE MAS TARDE SON EXTENDIDAS-SOPLADAS PARA CONVERTIRSE EN ENVASES TALES COMO LAS BOTELLAS DE PET. LA INVENCION SE REFIERE A PROFORMAS QUE TIENEN UNA ESTRUCTURA MULTICAPA Y QUE INCORPORAN UNA CAPA INTERNA RECICLADA, EMBEBIDA ENTRE DOS CAPAS DE MATERIAL VIRGEN QUE ESTAN SOBRE EL EXTERIOR Y EL INTERIOR DE DICHA PROFORMA. LA VARILLA DE NUCLEO ESTA DISEÑADA MEDIANTE LA INVENCION DE MANERA QUE LA CAPA INTERNA DE LA PROFORMA TENGA UN GROSOR MINIMO EN SU AREA DEL FONDO Y QUE EL GROSOR MINIMO SEA CONSIDERABLEMENTE MAYOR QUE EL DE UNA CAPA CONOCIDA EN LOS PROCEDIMIENTOS ACTUALES. EL INCREMENTO DE GROSOR DE LA CAPA SE CONSIGUE DISEÑADO EL NUCLEO (2) EN SU PARTE DEL EXTREMO FRONTAL (3A, 3B) EN UNA FORMA DESENRROLLADA. LOS POSIBLES DISEÑOS DE LOS EXTREMOS FRONTALES DESENROLLADOS SON UNA PARTE PLANA (3B) O UN HUECOPOCO PROFUNDO (3A). CON DICHO DISEÑO DE LA VARILLA DEL NUCLEO LA INVENCION ASEGURA QUE LA CAPA MEDIA, RECICLADA NO ALCANCE LA SUPERFICIE INTERIOR DE LA PROFORMA PARA DAR A LA PROFORMA, AUNQUE SE UTILIZA MATERIALES TERMOPLASTICOS RECICLADOS, CON COMPATIBILIDAD CON LOS ALIMENTOS.
