Abstract

PROCESO PARA LA REALIZACION DE PIEZAS QUE COMPRENDEN UNA PARTE DE SOPORTE RIGIDO O SEMIRIGIDO REVESTIDO DE UNA PARTE DE RECUBRIMIENTO DECORATIVO FLEXIBLE, CARACTERIZADO EN QUE CONSISTE: ESTADO PRETENSADO SOBRE EL REBORDE PERIFERICO (16) DE LA IMPRONTA HUECA (11) DE UN MOLDE. LA ZONA QUE PERMANECE LIBRE DE DICHA PARTE FLEXIBLE, POR EXTENCION BAJO EL EFECTO DE LA PENETRACION DE UN CONTRAMOLDE (12) EN EL INTERIOR DE DICHA IMPRONTA HUECA (11), HASTA UNA DISTANCIA DEL FONDO DE ESTA QUE CORRESPONDE AL ESPESOR DE LA PIEZA ACABADA, PUDIENDO LOS BORDES DE DICHA PARTE FLEXIBLE PERMANECER INMOVILIZADOS POR APRIETE ENTRE LAS DOS MITADES DEL MOLDE. IDA EN ESTADO FUNDIDO, SEGUN LA TECNICA LLAMADA A BAJA PRESION, EN EL ESPACIO QUE SUBSISTE ENTRE LAS DOS MITADES DEL MOLDE, POR ENCIMA DE DICHA PARTE FLEXIBLE, DE MANERA A CHAPEAR ESTA CONTRA LA PARED DE LA IMPRONTA HUECA (11), SIENDO OPERADA DICHA INYECCION SECUENCIALMENTE POR UNA SERIE DE ORIFICIOS DE INYECCION (32) DE MANERA QUE LOS FRENTES SUCESIVOS DE MATERIAL FUNDIDO QUE PROGRESA CONSTANTEMENTE EN EL MISMO SENTIDO, NO SE ENCUENTRAN MAS QUE EN ESTADO CALIENTE, DE MANERA A LLENAR COMPLETAMENTE EL MOLDE SIN CREAR, EN LA PIEZA, LINEAS DE SOLDADURA QUE CORRESPONDEN A PLIEGUES O BORDES Y A PUNTOS INICIALES DE ROTURA MECANICA DE LA PIEZA. RIO LA PIEZA OBTENIDA Y EN CORTAR EL EXCEDENTE DE TEJIDO.
