Where the tomorrow will take us?
question the assumption, think deeply.
GRAIN BOUNDARY DIFFUSION
Lesser Dy/Tb, Lesser cost
In the conventional sintering process, in order to increase the coercivity of the sintered NdFeB magnet, the Neodymium is partly replaced by Dy (Dysprosium)/Tb(Terbium), and the coercivity (Hc) is greatly increased by increasing the magnetic anisotropy field of the main phase. However, this also result in significant reduction in the Magnet Remanence (Br). The grain boundary diffusion technology enables Dy/Tb concentrating at the grain boundary. The shell structure of this Dy/Tb element distribution “hardens”the grain boundary region with a very small amount of heavy rare earth to achieve higher coercivity (Hc) without reduction of Magnet Remanence (Br).

NET SHAPE PRESSING & MOLDING
Let's simplify it!
Net Shape Molding and Pressing Technology use customized mold to press each magnet to a almost finished shape directly, advatages: Eliminate the machining process of slicing, reduce cutting loss and save processing cost; Compared with the traditional method, reduce the machining cost of 3-10%.
​
RADIAL RING MAGNET
Ease of assembly, quieter and smoother
Our radial multi-pole Technology enables the creation of super strong, durable single-cast radial magnetized ring magnet with multi-poles. This replaces the conventional way of joining multiple pieces of arc magnet to form the radial multi-pole magnet.
It simplifies motor assembly process and enhances performance for precision application. It is flexible in magnetization direction for different applications and achieve quieter and smoother sense of control.

HOT PRESSED
Let's fill the Gap!
Hot Pressed/Formed magnet using anisotropic nano-crystalline powder is not commercially widely available at the moment. This Extruded magnet offers numerous advantages filled the gap between sintered magnet and bonded magnet.
​
-
Reduced Dy amount compared to sintered NdFeB magnets
-
Dy-free magnets with high coercivity possible.
-
Various magnetization patterns possible by design of magnetizing fixture (similar to sintered radial ring)
-
Excellent corrosion resistance due to the absence of internal porosity (ideally full dense material)
