• Preparation Of Raw Materials: First of all, we need to prepare the raw materials of permanent magnetic materials, which usually consist of rare earth metal alloys and other alloy materials. These materials need to be mixed according to a certain ratio, and through a special melting process to prepare the alloy material in block form.
• Powder Metallurgical Treatment: The alloy materials are pulverized into micron-sized powders, which are used in the subsequent molding process.
• Forming: The powder is pressed into the desired disc shape using a forming die. This process is usually done by injection molding, die casting, or extrusion.
• Sintering: After molding, the parts are sintered, which is the process of sintering the powder particles at high temperature and pressure into a dense and hard cemented carbide. In the high temperature sintering furnace, through the diffusion and migration between the metal grains in the alloy to improve the density and mechanical properties of the alloy.
• Grinding Process: The sintered parts will be subjected to precision grinding process, including plane grinding, cylindrical grinding, etc., in order to achieve the requirements of precision and surface quality.
• Surface Treatment: In some cases, it is necessary to treat the surface of the permanent magnet material, such as nickel plating, spraying, etc., in order to improve its corrosion resistance.
• Inspection And Packaging: Finally, the processed permanent magnet discs need to be inspected to ensure that their magnetic properties and appearance meet the requirements, and then packaged for transportation and storage.
