Neodymium Iron Boron Magnet Quality – In the past 30 years, with the extensive development of magnet products, NdFeB magnets have been widely used in various industries, especially in magnetic levitation, electronic digital products and other industries. In the past 30 years, there have been many different brands. Consumers are also confused about how to judge the quality of NdFeB magnets. MPCO Magnetic Industry Co., Ltd. tells you to judge the advantages and disadvantages of NdFeB magnets, which should be considered from three aspects: magnet performance, magnet size and magnet coating.
Control of raw material production to ensure the performance of the magnet: First, consider whether the raw materials used by NdFeB manufacturers meet the national standards, and second, consider the advanced production technology of NdFeB magnet manufacturers. At present, advanced technologies include sheet ingot casting technology, hydrogen crushing technology and jet milling technology. Secondly, we should consider whether to adopt the two-part compression molding method, which is also the characteristics of the production of NdFeB magnets in China. Finally, we should monitor quality during the production process. PFM can be used for effective detection. We can select the desired NdFeB magnet model by looking at the various magnet parameters.
How to Judge Neodymium Iron Boron Magnet Quality
Machining ability to ensure the size of the magnet: NdFeB magnets have various shapes, and different shapes of NdFeB magnets have different sizes. It is difficult to form in one production in normal production, and it has to go through cutting and production processes. The size of high-quality magnets also has a large impact, and the size of the magnet depends on the processing capacity of the factory. Because only in this way, we can continue to meet the needs of our customers while saving manpower and resources and making the company more competitive.
The quality of the coating determines the life of the magnet: a magnet without a magnet coating has a life of 20-30 years at 51 ° C in 150 ° C air and needs to be plated on the surface. In the prior art, a layer of insulating material is usually plated on the surface of the magnet to prevent external substances from corroding the magnet. Currently, nickel, copper and other chemical substances are commonly used for isolation, but in some special cases, the phosphating method should be used. The customer should select the plating process according to the product work requirements.
In summary, to judge the quality of NdFeB magnets, it is necessary to understand the production process and fully understand its performance, size, plating and so on.
