Abstract

SE DESCRIBE UN METODO PARA EL MOLDEO DE PIEZAS (2) DONDE PASA UNA CANTIDAD DE CALOR EN SU INTERIOR Y DONDE LA PIEZA (2) SE CALIENTA HASTA LA TEMPERATURA DE ABLANDAMIENTO DEL PLASTICO Y ESTA TEMPERATURA SE CONSERVA DURANTE EL TIEMPO HASTA QUE LA PIEZA (2) ADQUIERA LAS FORMAS REQUERIDAS MEDIANTE EL MOLDEO (1) Y SE ENFRIA MIENTRAS ESTA DENTRO DEL MOLDEO (1). ADEMAS SE DESCRIBE UN NUCLEO CALEFACTOR QUE SE PUEDE DOBLAR Y QUE SIRVE PARA LLEVAR A CABO EL PROCESO Y QUE TIENE COLOCADO UNA BOBINA CONDUCTORA DEL CALOR (6) EN UNA ENVOLTURA AISLANTE (5). ESTA ENVOLTURA AISLANTE (5) TIENE UNA CAPA DESLIZANTE (8) EN SU PARED EXTERIOR Y, EN EL CENTRO DEL NUCLEO CALEFACTOR (3) SE EXTIENDE UN DISPOSITIVO DE CONTRATRACCION EN DIRECCION LONGITUDINAL Y TIENE UNA ENTRADA (7) EN UN EXTREMO DEL NUCLEO CALEFACTOR (3) PARA EL DISPOSITIVO DE CONTRATRACCION (4) Y ESTE SALE EN LOS OTROS EXTREMOS HACIA EL EXTERIOR.
