        We focus on manufacturing certified strong neodymium iron boron magnets: they have passed the ISO 9001, 45001 and 14001 three major system certifications, and at the same time comply with the RoHS and REACH dual compliance standards. They are made of environmentally friendly materials and cover all grades from N35 to N56. The product does not contain elements such as Dy, Tb, and Gd, and can be exported normally. It combines high-strength magnetic force with compliant quality, meeting the magnetic requirements of various industrial scenarios.

        We specialize in high-quality N52 NdFeB strong magnets — crafted with premium rare earth materials, delivering 100% stronger magnetic force than standard magnets for superior, consistent performance. Our magnets feature a Ni-Cu-Ni plating finish that passes a ≥24-hour salt spray test, ensuring exceptional corrosion resistance. As 100% permanent rare earth magnets, they're ideal for industrial, electronic, and high-magnetic-demand applications.

          As an Apple-certified Gold Supplier, we specialize in high-performance neodymium magnets for consumer electronics (including Apple devices). Our products meet rigorous quality standards, delivering exceptional performance and a trusted credit guarantee — making us a reliable partner for premium consumer electronics supply chains, perfectly suited for magnetic components in precision devices like smartphones.

          As a professional factory specializing in custom neodymium iron boron magnets, we guarantee your needs with all-round professionalism in technology, production capacity, quality control and service: equipped with imported equipment to achieve a processing accuracy of ≤±0.05mm, and support customization of high-grade and special coatings. Full-process quality control + each batch comes with a third-party test report. At the same time, we provide precise sampling within 7 working days (including performance data), making customization more reliable with industry-level standards.

           Whether it is the "South/North Pole charging on the outside", "thickness through charging", or "circumferential through charging" of arc-shaped magnets, or the "axial charging", "radial charging", or "thickness through charging" of cylindrical/square plate magnets, they can all be custom-made according to your assembly, magnetic force application direction and other requirements. From structural design to magnetization process, the entire process is fully compatible Make sure that the magnetic force characteristics of the magnet are perfectly in line with the working conditions of your equipment.

          Whether it is an epoxy coating suitable for highly corrosive scenarios, a nickel-copper-nickel coating that combines rust prevention and wear resistance, a cost-effective galvanized coating, or a gold-plated coating that requires a good appearance and texture, all can be customized and produced as needed. The coating thickness and process parameters of neodymium magnets can be adjusted according to your working conditions (such as humidity and salt spray environment). Ensure that the corrosion resistance and service life of the magnet are perfectly in line with your usage scenarios.

          In response to export demands of magnets, we adopt a customized magnetic isolation packaging process - full-process protection from dedicated inner boxes, positioning pallets to sealed boxes, which can effectively prevent damage to magnets caused by collisions and magnetic interference during transportation. It simultaneously supports connection with global mainstream logistics channels such as DHL, FedEx, and SF Express, and takes into account various transportation methods including air and sea. No matter which country or region your order is sent to, it can achieve dual guarantees of safety protection and efficient delivery.

            Starting from the precise selection of high-quality raw materials, it goes through a series of refined processing steps such as bonding and shaping, precise cutting, chamfering and grinding, and then endows the NdFeB magnet with stable magnetic force through professional magnetization technology. Finally, it is delivered in standardized packaging - the entire process realizes closed-loop control from raw materials to finished products, ensuring the accuracy of each step of the process. It can also efficiently match customized requirements of different specifications and performances.
