When the production of flat planar spiral spring spiral spring production of the first to be designed specifically Archimedean spiral linear mold; Second, we must consider the winding process and heat treatment processes employed. Rectangular strip annealing before winding the first commercially available, can be hand wound when winding method, lathe winding method and special tools winding method. After the flat spiral spring is made, you can not immediately remove it, you should mold around the spring to the furnace heating, quenching temperature rise, remove the mold and spring combination will place it in a suitable oil quenching. Then, and then heating the assembly to a tempering temperature and for a time and then removed. Made good plane scroll spring coils should transition uniform, does not allow bump phenomenon, the surface should be smooth, side acute chamfering or circular arc. The surface should be flat spiral spring oxidation treatment or other preservative treatment.
