Abstract:
A method for a vacuum process of isostatic pressing of powder material comprises preparing an explosive charged rubber bag by charging a rubber bag with powder, forming a vacuum environment by putting the explosive charged rubber bag in a vacuum box, sealing an inlet of the explosive charged rubber bag which is in a vacuum state, and maintaining the vacuum state by putting the explosive charged rubber bag in a fluid contained in a reservoir by a predetermined depth in a state that the inlet of the explosive charged rubber bag has been sealed.
