Abstract

UN MOLDE PARA EL MOLDEO DE MATERIAS PLASTICAS POR MEDIO DE UN PROCESO EN EL CUAL EL CALOR NECESARIO ES APLICADO A LA MATERIA PLASTICA (K) EN CURSO DE MOLDEO MEDIANTE LA APLICACION DE UN CAMPO ELECTROMAGNETICO, ESTE MOLDE ESTA PRINCIPALMENTE CONSTITUIDO POR UN MATERIAL (3, 4) NO CONDUCTOR DE ELECTRICIDAD EN EL CUAL SON INCORPORADOS UNO O VARIOS ORGANOS (5, 6, 7) CONDUCTORES PARA EL CAMPO ELECTROMAGNETICO, DISPUESTOS Y CONFORMADOS PARA GUIAR EL CAMPO ELECTROMAGNETICO DE SUERTE QUE PRODUZCA EN LAS REGIONES ACTIVAS DE MOLDEO (K) UNA DISTRIBUCION SUSTANCIALMENTE CONTROLADA DE LAS LINEAS DE CAMPO Y DE LA INTENSIDAD DEL CAMPO ELECTROMAGNETICO. ESTOS ORGANOS CONDUCTORES PUEDEN TENER SUSTANCIALMENTE LA SOLA FUNCION DE VOLVER UNIFORME EL CAMPO ELECTROMAGNETICO EN CORRESPONDENCIA CON LAS REGIONES DE MOLDEO (K), O BIEN PUEDEN TENER TAMBIEN, O SOLAMENTE, LA FUNCION DE CONCENTRAR EL CAMPO ELECTROMAGNETICO EN CORRESPONDENCIA CON LAS REGIONES DE MOLDEO (K), DE SUERTE QUE EVITE O LIMITE UN RECALENTAMIENTO INUTIL DE LAS OTRAS REGIONES. SI EN EL MOLDE ESTAN PRESENTES UNAS PIEZAS INSERTADAS METALICAS O COMPORTAN PARTES CONDUCTORAS, ESTAS PIEZAS PUEDEN SER UTILIZADAS PARA CONSTITUIR CIERTOS ORGANOS CONDUCTORES INCORPORADOS EN EL MOLDE CON EL FIN INDICADO.
