Abstract

PROCEDIMIENTO PARA MOLDEAR POR SOPLADO Y ESTIRADO UN CUERPO HUECO, PRODUCIDO MEDIANTE MOLDEO POR INYECCION EN DOS CAPAS. CONSISTE EN MOLDEAR, MEDIANTE INYECCION, UN CUERPO TUBULAR PROVISTO DE FONDO Y COMPUESTO DE DOS CAPAS DE RESINAS SUPERPUESTAS; LA INTERNA, FACILMENTE ESTIRABLE Y MOLDEABLE POR SOPLADO, MIENTRAS QUE LA EXTERNA OFRECE DIFICULTADES. EL CUERPO TUBULAR ASI FORMADO, SE SOMETE A UN PROCESO DE MOLDEO POR SOPLADO DE AIRE CALIENTE Y ESTIRADO SIMULTANEO DE AMBAS CAPAS DE RESINA, TENIENDO CUIDADO DE AJUSTAR LA TEMPERATURA DE DEFORMACION TERMICA DE LA RESINA DIFICIL DE ESTIRAR Y MOLDEAR POR SOPLADO, DENTRO DE LA GAMA DE TEMPERATURAS DE DEFORMACION TERMICA DE LA OTRA RESINA. EL PROCESO SE TERMINA CUANDO EL CUERPO TUBULAR HA ADQUIRIDO LA FORMA DESEADA. COMO RESINAS FACILMENTE MOLDEABLES POR SOPLADO Y ESTIRADO SE USAN: RESINAS DE TEREFTALATO DE POLIETILENO Y RESINAS DE CLORURO DE VINILO, Y COMO DIFICILMENTE MOLDEABLES SE USAN: PVC, ESTIROL, ACRILO, ABS, AS, ACRILONITRILO Y SIMILARES. ,
