Abstract
EN UN PROCESO PARA PRODUCIR UN ARTICULO MOLDEADO, MEDIANTE EL CALENTAMIENTO DE UNA LAMINA DE RESINA TERMOPLASTICA Y DESPUES TERMOFORMAR UNA PARTE A SER MOLDEADA, SE DESCUBRE EL MEJORAMIENTO QUE COMPRENDE EL CALENTAR DICHA PARTE A SER MOLDEADA, PONIENDOLA EN CONTACTO CON UNA PLANCHA CALENTADORA, MIENTRAS QUE UNA PARTE POR LO MENOS, DE LA PARTE NO MOLDEADA DE LA LAMINA DE RESINA TERMOPLASTICA, NO SE CALIENTA PONIENDOLA EN CONTACTO CON UNA PLANCHA CALENTADORA, Y ENTONCES CALENTANDO LA PARTE A SER MOLDEADA Y UNA PARTE POR LO MENOS DE LA NO-MOLDEADA AL PONERLA EN UN ESTADO DE "NO-CONTACTO" CON UN APARATO CALENTADOR. TAMBIEN SE DESCUBRE UN APARATO TERMOFORMANTE PARA PRODUCIR UN ARTICULO MOLDEADO, CALENTANDO UNA LAMINA DE RESINA TERMOPLASTICA CON UN DISPOSITIVO CALENTADOR Y DESPUES TERMOFORMAR UNA PARTE A SER MOLDEADA CON UN TROQUEL, DONDE DICHO DISPOSITIVO CALENTADOR, ESTA PROVISTO CON UNA PARTE CALENTADORA DIRECTA, QUE TIENE UNA PLANCHA CALENTADORA, QUE ESTA EN CONTACTO DIRECTO CON LA PARTE A SER MOLDEADA DE LA LAMINA DE RESINA TERMOPLASTICA, Y UNA PARTE CALENTADA DE "NO-CONTACTO" QUE ESTA, ENTRE LA PARTE DE CALENTAMIENTO DIRECTO, Y EL TROQUEL Y FUNCIONA PARA CALENTAR TODA LA LAMINA DE RESINA TERMOPLASTICA, EN UN ESTADO DE "NO-CONTACTO".
