Abstract
UN ARTICULO QUE TIENE UNA FORMA GEOMETRICA COMPLEJA SE OBTIENE MEDIANTE EL MOLDEO POR COINYECCION CONSECUTIVA DE UN PRIMER Y SEGUNDO MATERIAL SUSTANCIALMENTE SIN UNA PAUSA DE TIEMPO ENTRE LAS DOS INYECCIONES. LA PRESION, TEMPERATURA E INDICE DE FLUJO DE MASA SE CONTROLAN PARA OBTENER UNA DISTRIBUCION HOMOGENEA DE LOS DISTINTOS FLUJOS DEL MATERIAL INYECTADO Y PARA QUE SE ENCUENTREN EN UNA CONDICION FLUIDA Y SE FUNDAN ENTRE SI EN EL PUNTO DE ENCUENTRO.
