How do magnet manufacturers control the quality of NdFeB strong magnetism

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 manifested in the following three aspects: magnet performance; magnet size ; magnet plating.

1.Magnet performance
The performance guarantee of NdFeB blank material is the first and most basic premise.
1, magnet blank manufacturers according to business needs to prepare different grades of NdFeB materials.
The advanced nature of the magnet production process also determines the performance quality of the magnet.
3. The quality control in the process of sintering is also very important.
2.Magnet shape dimension and tolerance
Use various shapes of NdFeB magnets, such as round, cylindrical, special-shaped, square, tile, trapezoidal. Different shapes of magnets are processed by different machine tools, and skilled technology and high-precision processing equipment also determine the accuracy of the product.

2.Surface coating of magnet
The coating of the magnet coating includes zinc, nickel, nickel-copper-nickel, electroplated copper and gold, silver, etc. Jiada Magnetoelectric has its own electroplating workshop, which can electroplate magnets according to different needs of customers.
The quality of NdFeB magnets is simply to control the performance of raw materials, control the dimensional tolerances during processing, grasp the time during electroplating, and confirm the coating thickness after electroplating. Detect the magnetic flux of the magnet and the gauss value of the surface, etc. The accuracy of measuring dimensions with vernier caliper and micrometer; The coating, the color and brightness of the coating and the binding force of the coating can be observed through the appearance to observe the smooth surface of the magnet, with or without spots and corners, so as to evaluate the overall quality of the magnet.
Youlian Magnetic Industry has a complete testing process, advanced testing equipment at home and abroad, and careful process control to ensure the quality of magnets and provide a stable product foundation for customer development.
