Abstract
The technology of this invention is to combine the advantage of cold and hot forming magnetic component. Use the advantage of hot forming technology which is 3D complex forming, and use hot-forming magnetic powder to form magnetic component body. Single or multiple rod spaces including T shape, “I” shape or rod shape are previously reserved, and advantage of cold forming technology is used to produce core rod in the highest density of magnetic line, in order to provide the source of high induction magnetic line. Next, assemble single or multiple core rods with body, in order to obtain assembling magnetic component of final desiring magnetic induction.
