A method for making feeder. The feeder is set in a mold that is used in the casting metal. The feeder is composed of a feeder stock (31), which surrounds an inner cavity (36) as the volume of the feeder (36), which is made of exothermic and / or insulated feeder materials (30). A feeder opening (35) is constructed in the bottom area (34), and the inner cavity (36) has a larger diameter than the diameter of the feeder opening (35) in at least one part of the region, and the feeder (31) of the feeder (31) is manufactured by the injection in the core ejector. It is characterized in that a cavity (14) that imitates the external contour of the feeder (31) of the feeder (14) is constructed in order to produce a one piece feeder Library (31) having a pre given shape structure in a two piece core box (10) having a lower box body (11) and a upper box body (12), and a cavity (14) that imitates the outer contour of the feeder (31) of the feeder (31), and is made in the cavity (14) for manufacture. \ The inner cavity (36) in the feeder (31) of the feeder (36) is made to regulate the reversibly expanded frit (15) so that the wall area (32), the cover area (33) and the bottom region (34) of the feeder (31) described in the ejector are provided to the feeder in the intermediate space (41) respectively. The material (30) is constructed, and the intermediate space (41) is between the expanded frit (15) and the inner wall (40) of the cavity (14), in which the feeder openings (35) arranged in the bottom area (34) of the feeder (31) of the feeder (35) are constructed by the first diameter of the first diameter (37) through the frit (15). And the frit (15) does not exceed the diameter of the bottom section (37) in its unexpanded position so that the completed feeder Library (31) can be removed by the feeder (15) with the feeder (35) in the core box (10) when the core box (10) is demoulding.
