Description
With the development of electronics miniaturization, magnetic components are strongly emerging as major parts for supplying the torque in the mini-operating system. Further, a three-dimensional flux design should be required for the hard-magnetic components having two or more anisotropic axes, in order to operate efficiently within the limited component size. In this respect, magnetic metal injection molding can be bound to be the main manufacturing process for designing the multi-axis hard magnets, especially for the miniaturized and complex parts.
In this research, we propose new multiscale modeling in the magnetic metal injection molding to calculate the anisotropicity (magnetic alignment) in the magnets, and by extension, possible to design the multi-axis magnets for electronics miniaturization through our approach. By developing the magnetic particle orientation model and magneto-rheological model for micro and macro-scale phenomena, particle motion in the molten polymers can be predicted during field-induced injection molding. This system can be made up of three factors; i) the magneto-rheological model for the macro phenomenon, ii) the magnetic particle orientation model for the micro phenomenon, iii) Simulation of the mold flow with the external magnetic field.
