Abstract

The invention provides a small ultrathin flaky magnetic core and a production process thereof, and relates to the technical field of magnetic cores. The small ultrathin flaky magnetic core production process comprises the following production process steps that S1, oxide particles of iron, manganese and zinc and salt particles of the oxide particles are put in storage for inspection; S2, after inspection is completed, oxide particles of iron, manganese and zinc and salt particles of the oxide particles are evenly mixed through a mixing machine; s3, after mixing is completed, the mixed particles are dried through drying equipment; s4, the dried mixed particles are guided into a mold groove in a mold pressing device, and a blank is pressed according to product operation guidance; and S5, the thickness of the green bodies and the pressed green body types are inspected through inspection equipment, and batch numbering is conducted on the inspected green bodies. The thickness size of the magnetic core body is effectively controlled and detected through a precise instrument, integrated forming production of the magnetic core body is achieved, the production efficiency is improved, and the operation process is greatly simplified.

Description

technical field [0001] The invention relates to the technical field of magnetic cores, in particular to a small ultra-thin sheet magnetic core and a production process thereof. Background technique [0002] Magnetic core: A magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core body materials. Manganese-zinc ferrites are characterized by high magnetic permeability and high magnetic flux density, and have low loss characteristics. Nickel-zinc ferrite has the characteristics of extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers in various electronic devices. [0003] In order to meet the requirements of improving efficiency and reducing size and weight of switching power supplies, a transformer core with high magnetic flux density, high frequency and low loss is required. Al...
