Our core technology for customizing NdFeB magnets

Neodymium magnets are made from a combination of neodymium, iron, boron, and other components. These magnets are known for their high magnetism and are widely used in various industries. The core technologies involved in producing customized neodymium iron boron magnets include:


1.melt:The first step in producing NdFeB magnets is to melt and alloy the raw materials. Neodymium, iron, and boron are combined in precise proportions and melted in a vacuum induction furnace. This process ensures the uniformity of the alloy and eliminates impurities.


2.Hydrogen explosion and jet grinding:Once castings are formed, they will be crushed into particles of several micrometers. The size of the powder is crucial for determining the magnetic properties of the final magnet.


3.Pressing and sintering:Press the particles into a compact shape using a hydraulic press. Carefully control the pressing process to obtain the required magnetic properties. Then, in a carefully controlled atmosphere, sinter and compact the powder at high temperatures to combine the particles and form a solid magnet.


4.inspect:Detection technology is crucial for NdFeB magnets, ensuring their quality, performance, and safety, thus supporting our core technology.


5.Processing and molding:After sintering, the magnet undergoes further processing and forming to achieve the final desired shape and size. This may involve cutting, grinding, drilling, and surface treatment to enhance the performance of the magnet and protect it from corrosion.


6.Optional GBD process:GBD is currently one of the important development directions of Ketian, with multiple process routes. This type of magnet is widely used in fields such as the main drive motor of new energy vehicles, air conditioning compressors, and intelligent robots. It is customizable and can meet the needs of customers.


7.magnetization:The final step in manufacturing customized NdFeB magnets is magnetization. Strengthen the magnetic field to align the magnetic domains inside the magnet, thereby maximizing its magnetic strength and performance.


In addition to these core technologies, there are several other important considerations in the production of customized neodymium iron boron magnets, such as quality control, surface treatment, and magnet assembly. These technologies can ensure the production of high-quality and high-performance NdFeB magnets according to specific customer requirements.
