<p>The present invention relates to a filter for a low pressure casting machine and a manufacturing method thereof, capable of efficiently removing oxide formed by contact between impurities and air in a molten metal and enabling to reuse right away after removing coagulation from a cast wheel, wherein the filter is formed by vacuum extrusion molding and is installed on a stoke connecting a metal mold and a warming furnace. The filter comprises a filter area which can be located on the stoke and purifies the impurities contained in the molten metal passing through the stoke; and a fixed area connected to the external circumference of the filter area and fixed on the internal side of the stoke. The filter area has multiple filter holes.</p> |
