Thick square high-suction magnets are thickened square permanent magnet products with large volume, thick thickness and super strong magnetic adsorption force. This kind of magnet adopts regular square structure, with thickened integral design, solid and stable body, no deformation and strong bearing capacity. The main raw material is high-grade high-performance neodymium iron boron magnetic material with high magnetic energy product, which has ultra-high magnetic density and super strong adsorption force, and is a core magnetic component for industrial heavy adsorption, fixed positioning and magnetic force support. Different from thin square magnets, thick square high-suction magnets are thickened and optimized in overall thickness and volume, which greatly improves the magnetic reserve and single adsorption force, and can meet the heavy-load magnetic adsorption requirements of industrial scenarios.

The production process of thick square high-suction magnets is mature and stable, including raw material pressing and sintering, square precise cutting, six-sided fine grinding, right-angle chamfering, surface anti-corrosion coating treatment and high-strength magnetization. In the production process, high-density sintering technology is adopted to ensure the internal compactness of the magnet, no pores and no impurities, so as to avoid magnetic attenuation and insufficient magnetic force caused by internal defects. The six-sided fine grinding process ensures that each surface of the square magnet is flat and smooth, the right angle is standard, the dimensional tolerance is small, and the assembly fitting degree is high. After high-pressure saturation magnetization, the magnet can give full play to the maximum magnetic performance of the raw material, with strong and lasting magnetic force. The surface is treated with thickened nickel plating or epoxy coating, which has excellent corrosion resistance, wear resistance and high temperature resistance, and can adapt to harsh industrial working environments such as high temperature, humidity and dust.

The core advantages of thick square high-suction magnets are super strong magnetic suction, stable structure, strong durability and wide adaptability. Firstly, the thickened solid structure greatly increases the magnetic volume and magnetic reserve. The single adsorption force of large-size thick square magnets can reach dozens of kilograms or even hundreds of kilograms, which can easily realize heavy workpiece adsorption and fixed positioning; secondly, the square regular structure has strong stability, uniform stress on the whole body, not easy to crack and deform, and can maintain stable working performance under long-term heavy-load adsorption state; in addition, the product has excellent anti-demagnetization performance and temperature resistance, will not produce magnetic attenuation and demagnetization phenomenon under long-term high-temperature and heavy-load working conditions, with long service life and high working stability.

Thick square high-suction magnets are mainly used in industrial heavy-load adsorption, mechanical equipment fixing, mold processing positioning, iron material handling, warehouse sorting equipment, and large mechanical auxiliary fixing. In industrial processing and manufacturing, they are used for magnetic fixing of large mechanical workpieces, adsorption positioning of mold processing, and auxiliary fixing of welding equipment, which can replace traditional fixture fixing, improve processing efficiency and simplify operation procedures; in material handling, they are applied to magnetic crane accessories and iron material sorting equipment, realizing fast adsorption and handling of heavy iron workpieces; in mechanical equipment assembly, they serve as stable magnetic fixing parts of large equipment brackets, base positioning magnets and mechanical limit components; in warehouse and logistics sorting, they are used for magnetic identification and fixed sorting of iron materials, improving sorting efficiency and automation level.

Thick square high-suction magnets can customize side length, thickness, magnetic grade and surface treatment according to customer demand. High-grade N52, N55 high-magnetic neodymium iron boron materials can be selected to further improve magnetic suction; special high-temperature resistant materials can be customized for high-temperature working scenarios. The product has the characteristics of large magnetic force, stable structure, strong load-bearing capacity, long service life and high cost performance. It solves the problem of insufficient adsorption force and unstable fixation of ordinary thin magnets in heavy industrial scenarios, and is an essential high-strength magnetic accessory for heavy industrial manufacturing, mechanical processing and automated handling equipment. It has extremely high practical value and market popularity in the industrial field.
