A manufacturing method for a permeable die steel stacks and fixes a plurality of fixing blocks to form a molded die having an emplacing space which contains and fixes a plurality of polymeric wires. A metallic powder and an adhesive are installed in the emplacing space to form a green type, and to completely enclose the polymeric wires, after being mixed together. Next, the green type is heated up to totally vaporize the polymeric wires and is then cooled down, so as to constitute a metallic product having breathing holes, for serving as a die steel.
