Description

Technical Field

[0001] The utility model relates to the technical field of iron oxide core production, in particular to a pressing and forming device for an iron oxide core. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices.
