Light density and low cost of ferromagnetic compounds (hard ferrite magnets) create a high-cost performance. Therefore, it has the largest market demand and is the most extensively used in the field of modern home appliances, office supplies, communication devices, and defense.

The orientation magnetization process can be completed in the process of injection molding, furthermore, insert molding can also be used to achieve the required products, those can reduce the subsequent process and total system cost.
