Ndfeb, simple is a kind of magnet, and we usually see the difference is that the magnet from excellent magnetic, known as 'magnetic king'. Ndfeb contains a large number of rare earth elements, and neodymium iron and boron, its characteristics of hard and brittle. Ndfeb is how to make then? 12 years magnet manufacturer expert to tell you. Sintered ndfeb permanent magnet is one of the application of powder metallurgy technology manufacturing ferrous permanent magnet materials. Main process are: formula orientation, smelting, milling, molding, sintering, mechanical processing, electroplating processing, etc. One of the oxygen content control is an important index of measuring technology level. Production facility of our company to choose the high vacuum melting, sintering furnace, and advanced automatic control jet mill, ensure the basic anaerobic process operation, make the products have the breakthrough to improve the performance and use of temperature. Manufacturing supply ndfeb generally has the following four kinds: 1, the sintering process: ingredients - Melting ( Sling with) - - - - - - Broken ( Hydrogen break) - - - - - - Flour - Pressed - Sintering - Machining - Surface treatment - The magnetization. 2, bonding process: ingredients - Milling ( Rapid quenching, HDDR, alloy atomization) - - - - - - Mixed powder ( Adding additives, resin) - - - - - - Molding ( Pressing, injection molding, extrusion, without magnetic field orientation for same-sex) - - - - - - Curing - Coat - The magnetization. 3, hot pressing process: hot gay: ingredients - Milling ( Rapid quenching, HDDR, alloy atomization) - - - - - - High temperature compression molding - ( Machining) - - - - - - - table surface treatment The magnetization. 4, thermal deformation of the opposite sex: ingredients - Milling ( Rapid quenching, HDDR, alloy atomization) - - - - - - High temperature and pressure - High temperature extrusion - ( Machining) - - - - - - Surface treatment - The magnetization on an article: about magnets ( Magnetization) Orientation direction explanation: next article about rare earth permanent magnet materials
