Neodymium iron boron permanent magnet, also known as modern industrial monosodium glutamate, as a major high functional magnetic material in modern industry, promotes the advancement of modern technology and society, and is widely used in various fields. How to determine the advantages of permanent magnet products: magnetic function; The size of the magnet; Surface coating.

Magnetic function: The key to decision-making is to control the magnetic properties of the raw materials used in the production process.

1. According to the standard rules for purchasing raw materials, our company only sells high-end neodymium iron boron based on business needs or medium or low grade sintered neodymium iron boron.

2. The progressiveness of production technology also determines the functional quality of magnets.

3. Quality monitoring during the production process is very important.

Magnet shape size and tolerance value: Various shapes of neodymium iron boron magnets are used, such as circular, irregular, square, tile, and trapezoidal. Materials of different scales 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 techniques. Plating options can be applied to products according to customer requests. A brief summary of the quality of neodymium iron boron products is to grasp the functions, control the dimensional tolerances, and evaluate the appearance of coatings. Check the Gaussian surface of the magnetic flux of the magnet and wait for testing; Scale 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, whether it is colorful, and whether there are edges or corners missing.

Magnets themselves are not entirely composed of the main components neodymium, iron, boron, and other materials that are mixed and sintered after destruction. This way, our magnet raw materials are manufactured. The raw materials for magnets are mainly two types of circular and square, and the required sizes are all cut by a large blank material using a slicing machine. After cutting, the surface treatment is used to electroplating. Magnet electroplating is to maintain the anti-corrosion of the magnet Rust prevention is not related to magnetic force. After electroplating, the magnet still lacks magnetism and needs to be magnetized with a magnetizing machine. After magnetization, it becomes the powerful magnet we see.
