Abstract

LA INVENCION TRATA DE UN METODO PARA LA ELABORACION DE CUERPOS HUECOS VENTILADOS DE POLIPROPILENO, DONDE SE CALIENTA ANTES DE SU ELABORACION LA PIEZA MOLDEADA EN BRUTO EXTRAIDA DEL ALMACEN Y DENTRO DE UN HORNO O DE UN TRAMO CALEFACTOR Y DESPUES SE EXTIENDE EN DIRECCION AXIAL. POSTERIORMENTE A ESTE PROCESO SE INFLA. CON ESTOS PROCESOS SE PRETENDIA SUPERAR LAS DIFERENTES TEMPERATURAS EXISTENTES ENTRE LA TEMPERATURA DE SALIDA DEL PROCESO Y LA TEMPERATURA FINAL DEL MISMO. ESTO CONLLEVABA UNAS CIERTAS DESVENTAJAS PARA LA MANIPULACION DE LA PIEZA MOLDEADA EN BRUTO PREVIAMENTE , POR EJEMPLO PARA EL TRANSPORTE DE LOS HORNOS CALEFACTORES Y PARA EL TRANSPORTE DEL DISPOSITIVO DE ESTIRAMIENTO. POR LO TANTO, LA INVENCION ACONSEJA QUE LA PIEZA MOLDEADA PREVIAMENTE EN BRUTO SE CALIENTE EN UNA VIA DE PRECALENTAMIENTO Y A UNA TEMPERATURA POR DEBAJO DE LA TEMPERATURA DE ESTIRAMIENTO Y SE MANTENGA A ESTA TEMPERATURA PARA SU MANIPULACION. POSTERIORMENTE SE CALENTARA A ESTA TEMPERATURA DE ESTIRAMIENTO, SE ESTIRARA Y SE INFLARA.
