Abstract

EL INVENTO PERFECCIONA UN PROCEDIMIENTO, UNA INSTALACION Y UN ROLLO DE HOJA COMBINADO DE HOJAS DE TERMOPLASTICO TENSADAS O PRETENSADAS Y DE LAMINAS O PLACAS DE TERMOPLASTICO. EL PROCEDIMIENTO ES UNA EMBUTICION PROFUNDA CON MOLDE NEGATIVO QUE FUNCIONA CON UNA DIFERENCIA DE PRESION Y UN RECALENTAMIENTO DEL MATERIAL DE FUNDICION QUE AL EMBUTIRSE OBTIENE UN GOFRADO Y/O UNA DECORACION DE SUPERFICIE. LA DIFERENCIA DE TEMPERATURA ENTRE EL MATERIAL Y EL MOLDE ASCIENDE A MAS DE 30 K. UNA HOJA, LAMINA O PLACA DE AL MENOS DOS CAPAS Y UN GRUESO DE 150 M - 5000 M SE CALIENTA Y EMBUTE, SEGUN EL INVENTO, CUBIERTA DE UNA CAPA U HOJA SUPERIOR PROXIMA AL MOLDE, CUYA TEMPERATURA O CAMPO DE TEMPERATURA DE FLUENCIA Y DE CRISTALIZACION/FUSION ES DE 3 A 50 K INFERIOR A LA DE LA CAPA U HOJA INFERIOR Y/O QUE TIENE UN INDICE DE FUSION MFI 170 C/209 N/10 MIN QUE ASCIENDE A ENTRE 1/50 Y 3/5 DEL INDICE DE FUSION MFI 170 C/209 N/10 MIN DE LA CAPA U HOJA INFERIOR. EN AMBOS LADOS DE LA LAMINA SE INSTALAN DISPOSITIVOSDE CALEFACCION CON EL MISMO O APROXIMADAMENTE EL MISMO PODER DE CALEFACCION.
