How To Control The Quality Of NdFeB
Neodymium iron boron strong magnet is also known as modern industrial monosodium glutamate, as an important additive in modern industry, high-performance magnet to promote the progress of contemporary industrial fields, widely used in various fields, the quality of finished magnets mainly performance in the following three aspects: magnet performance;The size of the magnet;Magnet coating.
The performance guarantee of ndfeb raw material is the initial and most basic premise.
1. Magnet blank manufacturers prepare ndfeb materials of different grades according to business requirements.
2. The advancement of magnet production technology also determines the performance and quality of the magnet.
3. Quality control in each process of sintering is also very important.
Shapes, sizes and tolerances of magnets
Use ndfeb magnet in various shapes such as circle, column, profile, square, tile, trapezoid. Different shapes of magnets are machined by different machine tools. Skilled technology and high precision machining equipment also determine the accuracy of products.
The surface coating of the magnet
Magnet coatings include zinc, nickel, nickel copper, nickel plating copper and gold, silver, etc. magnetoelectric has its own electroplating workshop, which can electroplate the magnets according to different requirements of customers.
Neodymium iron boron magnet quality is good or bad, simply said that the control of raw material performance, processing control dimensional tolerance, grasp the time in the electroplating process, after electroplating to confirm good coating thickness.The magnetic flux and gauss value of the magnet are tested. Measuring accuracy with vernier caliper and micrometer; Coating, color and brightness of coating and coating adhesion, and can be observed by the appearance of the magnet surface smooth, no spots, no edges and corners, to evaluate the overall quality of the magnet.
Our company has a perfect testing process, advanced testing equipment at home and abroad, careful manufacturing process control, ensure the quality of magnets, to provide customers with a stable basis for the development of products.
