Galaxy Magnets have two types of hot-pressed Nd-Fe-B magnets, the hot-pressed isotropic Nd-Fe-B magnet (GHMⅡ) & the hot-extruded anisotropic Nd-Fe-B magnet (GHMⅢ). The hot-pressed isotropic Nd-Fe-B magnet (GHMⅡ) is produced by hot compression with rapidly-quenched Nd-Fe-B magnetic powder under high temperature. The hot-extruded anisotropic Nd-Fe-B magnet (GHMⅢ) is produced by the technology of hot compression-extrusion-deformation with rapidly-quenched Nd-Fe-B magnetic powder under high temperature. Characteristics:

1.High magnetic performance, with (BH)max in magnet radial direction reaching 240～390kJ/m3;

2.The magnet ring is radially-oriented with uniform magnetic field, which can guarantee silent motor operation and smooth torque output;

3.The magnet has high temperature resistance, with working temperature reaching 200℃;

4.The magnetic pole number and skew angle of the magnet shall not be necessarily pre-designated at pressing process, but changed by adjustment of magnetization yoke, which can guarantee greater design freeness for customers;

5.The magnetic wave form of the magnet can be customized as square wave or other special wave forms;

6.The magnet ring can eliminate the process of splicing into a circle. It can be magnetized for multi-poles, which gives motor assembly convenience;

7.The magnet is Nano-crystalline structure with high density and ED coating with excellent corrosion resistance;

8.The magnet is mainly applied on many kinds of automobile motors, servo motors and brushless motors for power tools.

4.The Sm-Co magnet has an extremely low temperature coefficient, generally -0.030%/K.

The Sm-Co magnets are comprehensively applied in the field of space and aviation, national defense and military electronics, micro-wave parts, communications , medical electronics, automobile, magnetic pump, instrument & meters, sorts of sensors and high-ten motors.

Injected Plastic-Bonded Magnets

注塑磁体（简称塑磁）是将热塑性树脂和磁粉混炼造粒后，使用注塑成型方法生产的粘结磁体。根据注塑磁体产品磁性能要求及使用环境的不同，可选用不同树脂和磁粉的组合以满足使用需求。由于注塑磁体使用注塑工艺成型，所以产品可设计成较复杂的形状，也可与其它零部件直接注塑组合为一体，形成组件。工艺可靠、简单，尺寸精度高。

与常用的烧结磁体（如烧结稀土永磁和烧结铁氧体）相比，注塑磁体的韧性较好，在冲击载荷作用下不易发生开裂。由于注塑磁体具有高性价比，所以广泛用于家用电器、汽车、办公设备、3C产品等领域。

The injected plastic-bonded magnet is manufactured by the injection molding technology with granulation materials of thermoplastic resin & magnetic powders. According with different magnetic performance and application, the injected plastic-bonded magnet can be produced by different combinations of resins and magnetic powders. Due to its injection molding, the magnet can be designed in complicated shapes and also plastic-injected with other parts as a complete assembly product.  

Compared with normal sintered magnets (sintered Nd-Fe-B and ferrite), the injected plastic-bonded magnet has a better ductility and crack resistance on some certain impact load. The injected plastic-bonded magnet has a high cost advantage, comprehensively applied in the field of home appliances, automobile, office equipment & 3C products, etc.
