Abstract

EN ESTE PROCEDIMIENTO SE PARTE DE UN GRANULADO EN FORMA DE VARILLAS DE MATERIAL TERMOPLASTICO REFORZADO POR FIBRAS. ESTE GRANULADO PUEDE SER LLEVADO EN CUALQUIER DISPOSICION A UNA ESTACION DE RECALENTAMIENTO, DONDE SE CALIENTA A UNA TEMPERATURA SUPERIOR AL PUNTO DE REBLANDECIMIENTO DEL MATERIAL. DESPUES DE CALENTAR UNA CAVIDAD DEL MOLDE A UNA TEMPERATURA POR DEBAJO DEL PUNTO DE REBLANDECIMIENTO DEL MATERIAL, SE VIERTE ESTE EN AQUELLA LOGRANDO UN RELLENO COMPLETO A ALTA PRESION. UNA VEZ ENFRIADO SE SEPARA EL CUERPO MOLDEADO DEL MOLDE. ESTE PROCEDIMIENTO TIENE LA VENTAJA DE QUE PUEDEN FABRICARSE PIEZAS COMPLICADAS SIN FALLOS CON CARACTERISTICAS MECANICAS ESPECIALMENTE FAVORABLES Y QUE EL PROCEDIMIENTO NO PRESENTA GRAN DIFICULTAD TECNICA.
