Zusammenfassung:	The present invention relates to a technological method of producing polygonal aluminium nut from polygonal hollow aluminium blank through cold extrusion. First make the polygonal shape and central hole of blank similar to those of product, but its opposite sides have dimensions smaller than that of product, then use cold-extrusion puncher pin to penetrate through the hole of blank, and finally extrude the blank to form the product. Said method can quickly produce a product with high strength, esthetic appearance, low cost and high utilization rate of material.
