We are constantly trying to improve ourselves in new thoughts, new technology and new working methods.
Shine Magnetics introduces a specialized series of neodymium magnets designed specifically for wireless chargers. Manufactured using high-quality sintered NdFeB materials, these magnets feature a high maximum energy product, a slim profile, and precise magnetic field distribution characteristics. Optimized for wireless charging systems, this series facilitates rapid alignment and secure attachment between chargers and devices—such as mobile phones, smartwatches, and earbuds—thereby effectively minimizing energy loss caused by positional misalignment and significantly enhancing both charging efficiency and user experience.
High-Precision Alignment, Reduced Energy Loss
The stable magnetic field generated by these magnets guides the device to automatically self-align with the optimal charging zone. This prevents issues such as slow charging or overheating caused by coil misalignment, thereby boosting charging conversion efficiency.
Slim, Compact Design for Space-Constrained Applications
Available in circular and ring shapes with thicknesses as low as 1mm and diameters ranging from 5mm to 30mm, these magnets can be seamlessly embedded within wireless charger panels or device receivers without compromising the product's overall thickness or aesthetic appeal.
Superior Corrosion Resistance and Surface Treatment
Standard models feature a triple-layer Nickel-Copper-Nickel (Ni-Cu-Ni) plating; alternative coatings—such as epoxy resin, gold, or zinc—are also available to meet specific salt spray test requirements and ensure adaptability across diverse operating environments.
High Coercivity and Thermal Stability
Utilizing grades ranging from N35SH to N52H, these magnets offer a maximum operating temperature of up to 120°C. They maintain stable magnetic properties—without demagnetization—even when exposed to the heat generated during wireless charging operations.
