Ndfeb permanent magnet is also known as modern industrial monosodium glutamate. As a kind of high-performance magnetic material in modern industry, it promotes the progress of modern technology field and society and is widely used in various fields. How to judge the advantages of permanent magnet products: 1. Second, the size of the magnet; Three, surface coating.

First, 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 needs sintered NdFeb.

2. The advanced production technology also determines the performance quality of the magnet.

3. Quality control in the production process is important.

2. Magnet shape size and tolerance value

The use of Ndfeb magnets in various shapes, such as round, shaped, square, tile, trapezoid. Different sizes of materials are processed using different machine tools to cut rough materials. Advanced technology and machine operators determine the accuracy of products.

Three, surface coating treatment

Surface coating coating quality, zinc, nickel, nickel copper nickel plating copper and gold plating processes. Electroplating options can be performed according to customer requirements. A short summary of the quality of NdFeb products is to grasp the performance, size tolerance control, judge the appearance of the coating detection and evaluation. Gaussian surface test to detect magnetic flux; Dimensional tolerances, accuracy that can be measured with vernier calipers; The color and brightness of the coating and the binding force of the coating can be observed through the appearance of the surface of the magnet smooth, whether there are spots, whether there are edges and corners, so as to evaluate the quality of the product.
