What is the manufacturing process of the powerful magnet
In terms of manufacturing process, there are two types of sintered NdFeB magnets and bonded NdFeB magnets. We mainly focus on sintered NdFeB magnets. Process flow of NdFeB magnet: batching → smelting ingot making/belt throwing → powder making → molding → sintering and tempering → magnetic testing → grinding → pin cutting → electroplating → finished products. Among them, batching is the basis and sintering tempering is the key.
Production tools and performance testing tools for NdFeB strong magnet blanks: smelting furnace, belt throwing furnace, jaw crusher, air flow mill, pressing and forming machine, vacuum packaging machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic property tester, Gauss meter. NdFeB magnet machining tools: centerless grinder, rounding machine, double end grinder, flat grinder, slicer, double side grinder, wire cutting, bench drill, profiled grinder, etc.
The processing method is because the NdFeB strong magnet is made by pressing the powder produced after the raw material is broken. The initial shape is called blank, and later, according to the customer's requirements, different shapes can be processed, such as: circular, circular, square, perforated, trapezoidal, concave convex, runner shaped, and some irregular shapes.
