Neodymium ferroboron permanent magnet, also known as modern industrial monosodium glutamate, as an important high-performance magnetic material in modern industry to promote the progress of contemporary technology and society, widely used in various fields, how to judge the most comprehensive advantages of permanent magnet products: First, magnetic performance; Second, the size of the magnet; Third, surface coating.

Magnetic properties
First, the key to the decision is to control the magnetic properties of the raw materials in the production process.
1, raw material manufacturers according to business requirements or middle or low sintering neodymium iron boron, raw materials to purchase the National Standards for raw materials, the company only sells high-grade neodymium iron boron.
2, the advanced production process also determines the performance of the magnet quality.
3, quality control in the production process is very important.
Size and tolerances of magnets
Using various shapes of neodymium iron boron magnets, such as circular, special-shaped, Square, Tile, trapezoidal. Different sizes of materials are processed using different machine tool cutting materials. Advanced technology and machine operators determine the accuracy of the product.
III. Surface coating treatment
Surface coating quality, zinc, nickel, nickel copper nickel plating copper and gold plating process. Product plating options can be performed according to customer requirements. A brief summary of the quality of neodymium iron boron products is to grasp the performance, size tolerance control, and judge the appearance of the coating detection and evaluation. Test the Gaussian surface of magnet flux, etc.. Dimensional tolerances, precision that can be measured with a cursor caliper; The coating, the color and brightness of the coating and the binding force of the coating, and the appearance of the magnetic surface can be observed to assess the quality of the product.
