Block special-shaped perforated NdFeB magnets are rectangular block-based special-shaped magnetic products with customized holes, including round holes, square holes, counterbore holes, threaded holes, and multi-hole combination structures, which are high-performance magnetic components integrating magnetic attraction and mechanical fixing functions. Based on the traditional square NdFeB magnet, the product realizes integrated design of magnetic performance and installation structure through precise drilling and hole processing, eliminating the need for auxiliary fixing accessories such as brackets and screws in subsequent installation, and greatly improving the convenience and firmness of equipment assembly. It is the most widely used customized special-shaped magnet in industrial assembly and equipment fixing scenarios.

In terms of process and performance, block special-shaped perforated NdFeB magnets are made of high-density sintered NdFeB materials, with stable magnetic performance, strong magnetic suction, and high magnetic uniformity. The hole processing adopts professional precision drilling and wire cutting technology, with smooth hole wall, no burrs, accurate hole position and aperture size, and the tolerance of aperture and hole spacing is controlled within ±0.015mm, which can be perfectly matched with standard screws, bolts, and positioning pins. The product supports customized processing of single hole, double holes, and multiple holes, and can design asymmetric hole positions and special-shaped hole structures according to customer equipment requirements. The surface is treated with multi-layer anti-corrosion electroplating, which has excellent oxidation resistance and corrosion resistance, and can work stably in various indoor and outdoor industrial environments. The block structure has strong structural stability, not easy to deform, and the perforated design does not damage the overall magnetic performance of the magnet, realizing the integration of strong magnetic attraction and mechanical locking fixing.

Block special-shaped perforated NdFeB magnets are widely used in industrial equipment assembly, fixture fixing, electronic equipment positioning, and new energy equipment fields. In the automation industry, they are used for fixed installation of automation fixtures, magnetic locking of assembly line tooling plates, and positioning and fixing of mechanical accessories, realizing stable and detachable installation of equipment components. In the electronic and electrical industry, perforated block magnets are applied to fixed installation of electrical equipment, positioning of circuit board magnetic parts, and fixing of communication equipment accessories. In the new energy industry, they serve as fixing components of photovoltaic equipment, wind power equipment accessories, and new energy battery brackets. In the hardware and mold industry, they are used for mold magnetic positioning, fixture clamping and fixing, and mechanical equipment base anti-slip positioning. In addition, they are also used in medical equipment, environmental protection equipment, and transportation equipment. The biggest advantage of perforated special-shaped block magnets is the integration of magnetism and mechanical fixing, which simplifies the equipment assembly process, reduces accessory costs, improves installation efficiency, and ensures the stability and safety of equipment operation. It is a versatile and high-cost-performance customized magnetic component in industrial manufacturing.
