Special Shaped Neodymium Magnets

Special shaped magnets refer specially to the magnets with irregular shape which primarily serve for specific demands. Injection molded magnets are ideally suited for special shaped magnets, but maximum energy product (BH)max of routine isotropic injection NdFeB molded magnets are limited to 60kJ/m3 which cannot satisfy most of special shaped demands. Sintered magnets are generally difficult to satisfy net shape directly owing to technology limitations in production process, thus machining process is essentially impossible to be avoided. Therefore, sintered Neodymium magnets are always criticized by its machinability, but special shaped Neodymium magnet still can be achieved via grinding or wire cutting process, hence its cost and production time are inevitability and significantly higher than conventional block magnets, bar magnets, ring magnets, disc magnets, rod magnets, arc magnets, countersunk magnets, and sphere magnets. Chinese Neodymium magnets manufacturers have already formed a clear division of labor over the years, thus processing enterprises fully learned processing experience from crystal industry and always trying to introduce the latest processing technology. With the process of functional complexity and miniaturization accelerates, consumer electronics exist large demand for special shaped Neodymium magnet. Laser cutting has become a new selection to machine special shaped Neodymium magnet with thinner thickness.

Customized special-shaped powerful magnets of various shapes from professional magnet manufacturers will be the basis for seeking better results, and naturally the key to making people more satisfied. Of course, we have a better grasp of the product selection, and will be able to have a very prominent effect in terms of reliability, so targeted selection will be necessary, and then can have outstanding performance in terms of quality.

Sintered NdFeB Magnets (also known as Neodymium magnets ,Neo magnets,or NIB) is the most powerful and advanced permanent magnet today .Sintered NdFeB magnets has the high remanence, high coercive force and high energy. It has very high performance and high cost ration.

The sintered Neodymium magnets have some limitations due to their poor corrosion resistance. In high-humidity, high-temperature, high-PH applications, protective coating is necessary for the sintered NdFeB magnets. Available coating includes NiCUNI ,Zn plating, Expoxy coating, parylene, and combinations of these coatings ( Detail coating opition for Sintered NdFeB magnets)

It can be easily formed into various sizes and different shapes, which are disc, ring, block, segment, special and so on.
