APPARATUS AND METHOD FOR FORMING METAL WIRE MESH FILTER

摘要

The present invention relates to an apparatus and a method for forming a metal mesh filter capable of forming a metal mesh filter formed to stack multiple filter layers by locally fusing a wire mesh after the wire mesh including filter holes is stacked in multiple layers. According to the present invention, the method for forming a metal mesh filter comprises: a stacking step of stacking wire meshes including filter holes by weaving a wire between a first mold and a second mold arranged at a distance away inside a forming space of a forming path; a preloading step of preloading the wire meshes stacked between the first mold and the second mold and bringing the first mold and the second mold in contact with each other; a resistance heating step of preliminary melting by resistance heating contact parts of the wire mesh contacted by preloading; a pressure fusing step of forming the metal mesh filter by pressure fusing the contact part of the preliminary melted wire mesh by pressing the wire meshes wherein the contacting part is resistance heated by the first mold and the second mold; and a step of cooling the metal mesh filter pressure fused.
