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. How to judge the advantages of permanent magnet products: first, magnetic performance; 2、 The size of the magnet; 3、 Surface coating.

1、 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 neodymium iron boron sintered according to business needs, medium or low-grade.

2. The advancement of production technology also determines the performance and quality of magnets.

3. Quality monitoring during the production process is important.

2、 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 the precision of the product is determined by advanced technology and machine operators.

3、 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 and free of spots, edges, and corners.
