Abstract

PROCEDIMIENTO DE CONTROL PARA LA ESPUMACION Y SINTERIZACION DE PLASTICO, PROFERIBLEMENTE DE POLETILENO EXPANSIBLE, PARA PRODUCIR PARTES DE PLASTICO (KT) EN CICLOS DE TRABAJO INTEGRADOS POR FASES, CUYOS PUNTOS DE PARTIDA Y TERMINO SE DETERMINAN AL ALCANZAR CIERTOS CRITERIOS DE CONTROL PREFIJADOS (K: SB, SC, SD, DEP, SEZ, SF, SGP) (=VALORES DE COMPARACION DE PRESIONES, TEMPERATURA Y/O TRANSCURSOS DEL TIEMPO EN EL PROCESO DE LA SINTERIZACION SP). EL JUEGO DE LOS CRITERIOS DE CONTROL (K) DE CADA CICLO DE TRABAJO SE DETERMINA MEDIANTE UNA DIFERENCIA (A) AVERIGUADA A TRAVES DE UNA MEDICION DE CALIDAD (QM) EN LA TORTA DE SINTERIZACION O EN LA PIEZA SINTERIZADA EN COMPARACION CON LOS CRITERIOS DE CALIDAD (QK). CADA VEZ EL JUEGO QUE DEMUESTRE LA MAYOR DIFERENCIA (A), SE ELIMINARA DE UN CIERTO NUMERO DE JUEGOS. SE DETERMINARA UN NUEVO JUEGO DE CRITERIOS DE CONTROL (K) CADA VEZ MEDIANTE LOS PROMEDIOS (VK) DE LOS CRITERIOS DE CONTROL (K) DE LOS JUEGOS RESTANTES Y DE UN VALOR DE DISPERSION ESTADISTICO (SW), CUYA GAMA DE DISPERSION SE REGULARA MEDIANTE EL PROMEDIO (VA) DE LAS DIFERENCIAS (A) DE LOS JUEGOS RESTANTES EN UNA ZONA DE TOLERANCIA YB) PREFIJADA. PREFERENTEMENTE, SE PREFIJARAN COMO CRITERIOS DE CONTROL (SEP, SD, SGP) UNA PRESION DIFERENCIAL O UNA TEMPERATURA DIFERENCIAL ENTRE LA TORTA DE SINTERIZACION Y LA CAMARA DE VAPORIZADO O LA PARED DE MOLDE, RESPECTIVAMENTE.
