Custom Injection Molded Bonded NdFeB Magnet , NdFeB+PPS Injection Molded Magnet
Plastic magnet is different from the traditional magnetic craft which made by mixing the magnetic particle with plastic medium, mixed and heated by the injection machine and then rip the mixture into the mould to get different shapes of production, this kind of process makes the Plastic magnetic has some unique advantages.
Commodity Description and Specification :
Magnetic powder is neodymium-iron-boron (NdFeB), either isotropic or anisotropic. And Polymer binders utilized are PA6, PA12 and PPS.
It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength.
Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/-0.005mm, it is suitable for high precision parts.
By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process.
Anisotropic NdFeB powder achieves the highest magnetic force as injection molded magnet. And it is possible to achieve BHmax 17GMOe, and can replace some of sintered products.
