ALUMINUM PRODUCT MANUFACTURING METHOD USING DIE CASTING METHOD AND ALUMINUM-TYPE BRAKE CALIPER MANUFACTURING METHOD USING SAME

摘要

There are provided a method of manufacturing an aluminum product and a method of manufacturing an aluminum brake caliper each using die casting, for improving flow and run of molten metal during casting and enhancing productivity and quality. In a method of manufacturing an aluminum product provided with opposing portions 3a, 3b opposed to each other with a hollow portion 2 interposed in between, and connecting portions 4 connecting the opposing portions at two sides thereof, the method includes a die casting step of performing casting by pouring molten metal of an aluminum alloy from a gate 6 for the molten metal formed in one of the opposing portions 3a, 3b via the connecting portions 4 and a bridge 5 connecting the two opposing portions 3a, 3b, and a bridge removing step of removing the bridge 5.
