If the filter screen is to be made into a triangular prism shape, the mould is correspondingly made into a triangular prism shape; assuming that the screen is to be made quadrangular, the mold is correspondingly quadrangular. The filter screen can be used in engine oil filter element, air conditioner, purifier, smoke exhaust ventilator, air filter, dehumidifier, dust remover and other parts. Preferably, the filter screen is used on an engine oil filter element to replace the traditional filter paper. The welded object 7 is not limited to a screen, and may be a bendable metal plate.
