Ndfeb permanent magnet is also called modern industrial MONosodium glutamate (MSG). As a high-performance magnetic material in modern industry, it promotes the progress of modern technology and society. It is widely used in various fields.The size of the magnet;Three, surface coating.
1. Magnetic properties
First, the key to the decision is to control the magnetic properties of the raw materials used in the production process.
1. The raw material manufacturer only sells high-grade ndFeb according to business requirements or middle or low grade sintered NdFeb.
2. The advanced production technology also determines the performance and quality of magnets.
3. Quality control in the production process is important.
2.Shape, size and tolerance of the magnet
Use the shape of ndFeb magnet, such as round, shaped, square, tile, trapezoid.Different sizes of materials are machined using different machine tools to cut rough materials. Advanced technology and machine operators determine the accuracy of the products.
3.surface coating treatment
Surface coating quality, zinc, nickel, nickel copper, nickel plating copper and gold plating process.According to customer requirements for product electroplating options.A brief summary of the quality of ndFeb products is to grasp the performance, dimensional tolerance control, judge the appearance of the coating inspection and evaluation.Test the gaussian surface of magnetic flux, etc.Dimensional tolerances, accuracy that can be measured with vernier calipers;The coating, the color and brightness of the coating and the adhesion of the coating, and the surface of the magnet can be observed through the appearance clean, whether there are spots, whether there are edges and corners off, to evaluate the quality of the product.
