Infiltration Production Practice for the Aluminum Alloy Die Castings

The small holes in the aluminum alloy die castings are likely to affect the air - tightness and press resistance performance of the parts. To improve casting performance, the infiltration technology can be used for filling up the holes. This paper presents following items: the principle of the infiltration technology, selection of the infusion, infiltration equipment, infiltration procedures, inspection method after the infiltration, and the notices in the production.
