Abstract

EL METODO PARA EL MOLDEADO A INYECCION DE MASAS DE RESINA POLIESTER INSATURADA POSIBLEMENTE REFORZADA CON FIBRAS, COMPRENDE LOS PASOS DE COMPACTAR LA MASA DE MOLDEADO EN UN CILINDRO DE ACUMULACION, GENERAR UNA PRESION SUBATMOSFERICA EN EL CILINDRO Y CALENTAR LA MASA COMPACTADA A UNA PRESION SUBATMOSFERICA MEDIANTE LA APLICACION DE UNA CARGA DE ALTA FRECUENCIA, E INYECTAR EL MATERIAL EN EL TROQUEL. EL APARATO PARA DESARROLLAR EL METODO INCLUYE UN CILINDRO DE ACUMULACION (5) PROVISTO CON UN PISTON DE INYECCION (10) Y CONSTITUIDO POR UN CUERPO DE MATERIAL TRANSPARENTE A LAS FRECUENCIAS ALTAS, CUYAS PAREDES INCORPORAN LAS LAMINAS DE ELECTRODO (7) DE UN GENERADOR DE ALTA FRECUENCIA.
