The bonded compression-molded NdFeB magnets, as for simple mold and high magnetic properties, stable working temperature,good corrosion-resistance, are widely used. They are possible to insert mold with other parts. If you need technical support about magnets, we could offer a one-stop magnet solution with high efficiency.

The complete combination of injecting process and high-property rare-earth powder makes it possible to form an easily strong bonded Ndfeb ring magnet for the speaker. Our factory owes complete industrial chain from raw material blank, cutting, electroplating, and standard packing. If you need technical support about magnets, we could offer a one-stop magnet solution with high efficiency.

Bonded neodymium magnets are isotropic and have the advantage of more advanced shapes compared to sintered magnets. The magnet needs to be coated with a layer of black or grey epoxy or parylene to protect them against corrosion. Our factory delivers high cost-effective magnetic parts to various parts of the world with technology developed through many years of experience. Please feel free to contact us if you have any problems with your existing magnetic parts.

The Hot-pressed NdFeB magnets divided into two types, Hot pressed isotropic NdFeB (MQ2) and hot -extruded anisotropic NdFeb magnet (MQ3). The Hot-pressed isotropic NdFeb magnet is produced by rapid quenched NdFeB magnetic pwder under high temperature through compression. The hot-pressed anisotropic NdFeB magnet is mainly anisotropic radially-oriented ring magnet which is produced through compression and extrusion deformation by rapidly quenched NdFeB magnetic powder under high temperature. Customized Injection Bonded NdFeB Ring Magnets

Compression bonded neodymium magnets are an excellent choice for a wide variety of applications, with relatively low tooling cost and quick turnaround,also over other magnet types (sintered neodymium, sintered samarium cobalt) that have limits to some shapes. Their high-energy product reaches up to 12 MGOe.Since no magnetic field is applied during the compression the finished product can be magnetized in any direction. Having epoxy as a binder in the manufacturing process for compression bonded magnets makes the magnets resistant to most industrial automotive fluids. Epoxy coated made it durable and more resistant to corrosion. If you need technical support about products, we could offer a one-stop magnet solution with high efficiency. Custom Compression Bonded NdFeB Ring Magnets
