China Courage Permanent Magnet Manufacturer 
Injection molding magnets, is a kind of magnetic powder (such as ferrite, NdFeB, etc.) and plastic matrix combination of composite materials, widely used in all kinds of motors, magnetic sensors, because the magnetism is not very strong, a lot of people want to know if there is no way to improve the strength of its surface magnetism.
1, Choose high-performance magnetic powder. Whether injection molded ferrite or injection molded neodymium iron boron, you can choose the magnetic powder grade, the larger the number represents the stronger the magnetic properties.
2, Replace with injection molded NdFeB. The magnetic strength of injection molded NdFeB will be much stronger than injection molded ferrite.

3, Increase the thickness of injection molded magnet. If possible, increase the thickness can also significantly improve the surface magnetic field strength.
4, the use of appropriate magnetization technology and equipment, as well as reasonable magnetization direction and mode (such as radial, axial, multi-pole, etc.).
The above 4 kinds of methods can effectively improve the surface magnetic strength of injection molding magnet, if you need injection molding magnet samples, quotes, please send us an inquiry to let us have a chat.
