How To 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 Aspects: magnet performance; magnet size; magnet coating.

1. Magnet performance

The performance guarantee of NdFeB blank materials is the initial and most basic premise.
Magnet blank manufacturers prepare different grades of NdFeB materials according to business needs.
The advanced nature of the magnet production process also determines the performance and quality of the magnet.
Quality monitoring in each process of sintering is also very important.

2. Magnet shape, size and tolerance

Utilize various shapes of neodymium iron boron magnets, such as round, cylindrical, special, square, tile, trapezoidal. Magnets of different shapes are processed by different machine tools. Skilled technology and high-precision processing equipment also determine the accuracy of the product.

3. The surface coating of the magnet

The coating of the magnet coating includes zinc, nickel, nickel copper-nickel, electroplated copper and gold, silver and so on. MPCO Magnet has its own electroplating workshop, which can electroplate magnets according to different needs of customers.

The quality of neodymium iron boron magnets is simply to control the performance of the raw materials, control the dimensional tolerances during processing, grasp the time during the electroplating process, and confirm the coating thickness after electroplating. Detect the magnetic flux of the magnet and the Gauss value of the surface magnetism; use a vernier caliper and a micrometer to measure the accuracy of the size; the color and brightness of the coating, the color and brightness of the coating and the bonding force of the coating, and the appearance of the magnet surface No edges or corners are dropped to evaluate the overall quality of the magnet.

MPCO Magnet 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.
