Core Technologies of Our Custom NdFeB Magnets
Neodymium magnets are made from a combination of neodymium, iron, boron and other ingredients. These magnets are known for their high magnetic properties and are widely used in various industries. The core technologies involved in the production of custom NdFeB magnets include:

1. Melting: The first step in the production of NdFeB magnets is melting and alloying the raw materials. Neodymium, iron, and boron are combined in precise ratios and melted in a vacuum induction furnace. This process ensures the alloy's homogeneity and eliminates impurities.

2. Hydrogen decrepitation and Jet milling: Once the castings are formed, they will be pulverized into particles in several microns. The powder size is critical in determining the magnetic properties of the final magnet.

3. Pressing and Sintering: The particles are pressed into a compact shape through a hydraulic press. The pressing process is carefully controlled to achieve the desired magnetic properties. The compacted powder is then sintered at high temperatures in a carefully controlled atmosphere to bond the particles together and form a solid magnet.

4. Inspection: Inspection technology is crucial for NdFeB magnets, ensuring their quality, performance, and safety, thus underpinning our core technologies.

5. Machining and Shaping: After sintering, the magnet undergoes further machining and shaping processes to achieve the final desired shape and dimensions. This may involve cutting, grinding, drilling, and surface treatments to enhance the magnet's performance and protect it from corrosion.

6. Optional GBD process: GBD is currently one of Ketian's significant developing direction, with multiple process routes. This type of magnet is widely used in fields like main drive motors for new energy vehicles, air conditioning compressors, and intelligent robots. It is customizable and selectable according to customer needs.

7. Magnetization: The final step in manufacturing custom NdFeB magnets is magnetization. A strong magnetic field is applied to align the magnetic domains within the magnet, maximizing its magnetic strength and performance.

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