Manufacturing Process of Neodymium Arc Magnets
The manufacturing of neodymium magnet adopts powder metallurgy technology. The raw materials with a proportion of neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, copper and boron are smelted into alloy ingots through the medium frequency induction melting furnace, then they will be crushed into 3~5μm powder and compressed molding in magnetic field. After the formed green compact are sintered in a vacuum sintering furnace and annealing process, thus permanent magnet blank have been produced. After the grinding, drilling, slicing and other machining processes, and then the surface treatment, neodymium magnets required by users are done.
With the advantage of high magnetic energy product, high coercivity force, and high energy density, neodymium permanent magnet materials have been widely applied in modern industrial and electronic technology, so that making the motor and other equipments are small, lightweight, and thin as possible. We are dedicated to providing competitive and integrated solutions and services to businesses and consumers. At present, our products have been used in more than 10,000 large and small companies. Our neodymium magnets have been exported to countries around the world. Based on “customer-centric" and customer’s demands , we gradually establish comprehensive advantages in the field of magnetic materials and provide customers with quality products and solutions, help customers improve profitability , enhance product competitiveness and reduce costs, and achieve commercial success.
