How to control the product quality of neodymium iron boron permanent magnets well

Neodymium iron boron permanent magnet, also known as modern industrial monosodium glutamate, as a high-performance magnetic material in modern industry, promotes the progress of contemporary technology and society, and is widely used in various fields. The three elements that determine the advantages of permanent magnet products are magnetic performance, magnet size, and surface coating.

Magnetic properties

Firstly, the key to the decision is to control the magnetic properties of the raw materials used in the production process.

1. According to the national standards for purchasing raw materials, our company only sells high-grade neodymium iron boron based on business needs or mid to low-grade sintered neodymium iron boron.

2. The progressiveness production process also determines the performance and quality of the magnet.

3. Quality monitoring during the production process is important.

Shape, size, and tolerance values of magnets

Utilize various shapes of neodymium iron boron magnets, such as circular, irregular, square, tile, and trapezoidal. Materials of different sizes are processed using different machine tools to cut rough materials, and advanced technology and machine operators determine the accuracy of the product.

Surface coating treatment

The coating quality of the surface coating, zinc, nickel, nickel copper nickel electroplating, copper and gold electroplating processes. We can perform electroplating options on products according to customer requirements. A brief summary of the quality of neodymium iron boron products is to grasp the performance, control dimensional tolerances, and evaluate the appearance of coatings. Detect the Gaussian surface of the magnetic flux of the magnet, etc. for testing; Dimensional tolerance, the accuracy that can be measured with a vernier caliper; The color and brightness of the coating, as well as the adhesion of the coating, can be observed through appearance to evaluate the quality of the product. The surface of the magnet is smooth, without spots, edges or corners.
