How magnet manufacturers control the quality of NdFeB magnets

NdFeB magnets are also known as modern industrial monosodium glutamate. As an important additive in modern industry, high-performance magnets promote the progress of contemporary industrial fields and are widely used in various fields. The quality of finished magnets is mainly reflected in the following three Aspect: magnet performance; magnet size; magnet plating.
First, magnet performance
The performance guarantee of NdFeB rough material is the most basic premise at first.
1. Magnet blank manufacturers prepare different grades of NdFeB materials according to business needs.
2. The advanced nature of the magnet production process also determines the performance and quality of the magnet.
3. Quality control in each sintering process is also very important. Zh
Second, the size and tolerance of the magnet
Utilize various shapes of NdFeB magnets, such as round, cylindrical, special-shaped, square, tile-shaped, trapezoidal. Different shapes of magnets are processed by different machine tools. Skilled technology and high-precision processing equipment also determine the accuracy of the product. Third, the surface coating of the magnet
The magnet plating layer includes zinc, nickel, nickel copper nickel, electroplated copper and gold, silver and the like. Jiada Magnet has its own electroplating workshop, which can perform corresponding electroplating treatment on magnets according to different needs of customers.
The quality of NdFeB magnets is simply to control the properties of raw materials, control dimensional tolerances during processing, grasp the time during the plating process, and confirm the thickness of the coating after plating. Test the magnetic flux and surface magnetic Gauss value of the magnet; use calipers and micrometers to measure the accuracy of the size; coating, color and brightness of the coating, and the bonding force of the coating. There are no edges or corners to evaluate the overall quality of the magnet.
Jiada Magnet has a complete testing process, advanced testing equipment at home and abroad, and careful process control to ensure the quality of the magnet and provide a stable product foundation for customer development.
