摘要

A composite powder filling device characterized by comprising powder boxes (10) having a plurality of powder chambres for separating and storing a plurality of kinds of raw material powder of different compositions, and gas introducing pipes (14) disposed on the bottom of the powder boxes and having spout holes for spouting gas, where gas is spouted from the spout holes so that the resistances to the flow of the plurality of kinds of raw material powder are substantially the same to make it possible to fill the plurality of kinds of raw material powder in cavities (24) at a time through the bottom openings in the powder boxes. Thereby, the plurality of kinds of raw material powder of different compositions can be filled in the cavities at a time without mixing.
