Abstract

PURPOSE: To prevent run defects, shrinkage cavities, etc. and obtain products of high quality by providing head parts communicating with the cavities formed into shapes corresponding to product shapes in a mold, mounting gas generators having opening parts communicating with the cavities therein, and exerting pressure to molten metal.
CONSTITUTION: For example, molten metal of Al alloy is teemed from a sprue 5 into cavitites 4 via a runner 6. When the molten metal arrives at the upper part of the cavities 4, and approaches to gas permeating plates 22, the gas generating agents 23 in gas generators 20 are thermally decomposed by the heat of the molten metal and produces gases. The pressure of the gases acts upon the top surfaces of the molten metal.
