Manufacturing PVC magnet powder metallurgy process, will contain a certain proportion of raw materials such as: neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, boron and iron smelting by medium frequency induction melting furnace to alloy ingot, then broken into three ~ 5μm powder and pressed in a magnetic field forming, sintering the green compact after molding and tempering aging in a vacuum sintering furnace, so you get a permanent magnet has a magnetic properties blank. After rough grinding, drilling, slicing and other machining processes, and then the surface treatment is required by the users of finished PVC magnet.
