Dongguan City, Xu-feng Hardware Products Factory is a professional manufacturer of metal springs, lathe parts and stampings businesses spring manufacturers, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. When the flat spiral spring production of flat spiral spring production of the first to be designed specifically for the Archimedes screw linear mold; Second, we must consider the winding process and heat treatment process used. Rectangular strip annealing before winding the first commercially available, can be used when winding hand winding method, turning around a system of law and special tools winding method. After the flat spiral spring is made, you can not remove it immediately, it should be around the spring to the furnace heated mold compression spring, when the quenching temperature rise, remove the mold and spring assembly to put in a suitable oil quenching. Then shaped spring, and then heated to a combination of tempering temperature and for a time and then removed. The prepared flat spiral spring coils should transition evenly, does not allow bump phenomenon, the surface should be smooth, acute side chamfer or an arc. The surface should be flat spiral spring oxidation treatment or other embalmed.
