Flat round thin magnets are ultra-thin disc-shaped permanent magnets with flat structure, regular circular outline and small thickness. This kind of magnet is thin and flat as a whole, with smooth and flat upper and lower end faces, no bulge and no deformation, and belongs to conventional high-precision thin-layer magnetic components. Flat round thin magnets are mainly made of high-performance neodymium iron boron magnetic materials, supplemented by ferrite and rubber magnetic materials. According to the thickness specification, they can be divided into conventional thin magnets and ultra-thin micro thin magnets. The thickness range is usually 0.5mm-5mm, with uniform thickness, regular roundness, and smooth surface, which is the most widely used thin-layer magnetic accessory in electronic products, precision instruments, and light industrial products.

The production process of flat round thin magnets focuses on precision thinning and flatness control. The production steps include raw material slicing, precise circular stamping or wire cutting, double-sided fine grinding, edge chamfering, surface electroplating and magnetization. The core processing difficulty of this product lies in controlling the overall flatness and thickness uniformity of the ultra-thin magnet to avoid warping, uneven thickness and surface burrs. Professional thin magnet processing equipment is adopted in the production process to ensure that the flatness error of each magnet is controlled within a very small range, the roundness is standard, and the upper and lower surfaces are parallel. After fine grinding and electroplating, the surface of the product is smooth and delicate, without scratches and oxidation spots, with good texture and stable quality. In terms of magnetization, flat round thin magnets usually adopt axial magnetization, with uniform magnetic force on the upper and lower surfaces, stable magnetic field, and no magnetic deviation.

Flat round thin magnets have outstanding advantages of thin thickness, light weight, high flatness, uniform magnetic force and small occupied space. Firstly, the ultra-thin flat structure is very suitable for thin and miniaturized electronic products and precision equipment, which can save installation space and meet the design requirements of light and thin products; secondly, the magnetic force distribution is uniform and stable, the magnetic field is flat and regular, which will not cause local magnetic force deviation, and can provide stable and balanced adsorption force and induction force; in addition, the product has good flexibility and adaptability, light weight, easy to assemble and paste, and will not cause excessive load on small equipment and electronic products. At the same time, the surface anti-corrosion treatment ensures that the product is not easy to oxidize and rust in daily and conventional industrial environments, with long service life and low attenuation of magnetic performance.

The application fields of flat round thin magnets cover consumer electronics, smart wearable devices, precision instruments, packaging hardware, medical supplies, and light industrial manufacturing. In the consumer electronics industry, they are widely used in mobile phone accessories, tablet computer magnetic parts, Bluetooth headset magnetic components, and camera fixed magnets, providing stable magnetic adsorption and positioning functions for thin electronic products; in smart wearable devices, they serve as core magnetic parts of smart watches, fitness bracelets, and intelligent glasses, meeting the miniaturization and thin design requirements of wearable devices; in the packaging industry, they are used for magnetic adsorption of gift boxes, cosmetic boxes, packaging boxes and iron box accessories, with strong adsorption force and hidden installation; in the medical field, they are applied to auxiliary magnetic parts of medical bandages, rehabilitation equipment and miniature medical detection instruments; in precision instruments, they are used for magnetic positioning and induction of small precision measuring tools and experimental instruments.

Flat round thin magnets support full-specification customization of diameter, thickness, magnetic strength and surface treatment. Conventional small-diameter micro thin magnets are suitable for miniature electronic products, and large-diameter flat thin magnets are suitable for industrial adsorption and packaging fixing. The NdFeB flat round thin magnets have strong magnetic force and small volume, which can realize strong adsorption in ultra-thin space; the rubber flat round thin magnets have good flexibility and can be bent properly, suitable for special curved fitting scenarios. With the continuous development of miniaturization and thinning of electronic products, flat round thin magnets have become indispensable basic magnetic components in the light industry and electronic manufacturing industry, with huge market demand and wide application prospects.
