Way of Cleaning Cast Metal : Use manual way with steel brush and beater Use mechanical auxiliaries Blasting Teknologi dan Rekayasa

Use Manual Way with steel Brush and Beater Usage with banding surface of cast metal until sand patching on surface to lose. This way modestly done but result less cleanly and less effective big scale Teknologi dan Rekayasa

Use Mechanical Auxiliaries This devices has limitation especially at the mechanism which is not enables for always can reach complicated parts from certain work substance contour. alat bantu mekanik Teknologi dan Rekayasa
