Abstract

EN EL CALENTAMIENTO DE LAS PREFORMA INYECTADAS FRIAS, RETIRADAS DE UN ALMACEN, QUE SE LLEVAN HASTA LA TEMPERATURA DE SOPLADO SOBRE UNA BANDA PARA INTRODUCIRLAS EN EL MOLDE DE SOPLADO EXISTE EL PELIGRO DE QUE EL CALOR, QUE ACTUA UNICAMENTE DESDE EL EXTERIOR, NO SE REPARTA SUFICIENTEMENTE SOBRE LA SECCION, DE MODO QUE LA PARED INTERIOR NO ALCANCE LA TEMPERATURA DE SOPLADO NECESARIA Y QUE SE SOBRECALIENTE LA PARED EXTERIOR. PARA EVITAR ESTO SE CALIENTAN LAS PREFORMAS EN PRIMER LUGAR HASTA UNA TEMPERATURA (TMAX1/TMIN1) INFERIOR A LA TEMPERATURA DE SOPLADO (TBL), SE ENFRIAN A CONTINUACION Y SE CALIENTAN NUEVAMENTE HASTA UNA TEMNPERATURA (TMAX3/TMIN3) LIGERAMENTE SUPERIOR A LA TEMPERATURA DE SOPLADO. A CONTINUACION SE DEJAN LAS PREFORMAS SOBRE LA BANDA PARA PRODUCIR EL EQUILIBRIO DE TEMPERATURA O PARA QUE SE ENFRIEN LIGERAMENTE. LA SEPARACION DE LOS SOPORTES DE LAS PREFORMAS DE LA CADENA DE TRANSPORTE ES AJUSTABLE PARA EVITAR PERDIDAS POR RADIACION DE CALOR. EL CUELLO DE LAS PREFORMAS SE PROTEGECON UNA VAINA DE PROTECCION PARA QUE NO SE CALIENTE.
