Filter mesh, also known as filter screen, is made from metal wires with various mesh sizes. Its function is to filter molten material flow and increase resistance, thereby removing mechanical impurities and enhancing the mixing or plasticizing effect. It features acid and alkali resistance, temperature resistance, wear resistance, and more. It is mainly used in industries such as mining, oil, chemical, food, and mechanical manufacturing. Filter mesh is categorized into textile fiber filter mesh and metal filter mesh.
