The complete combination of injecting process and high-property rare-earth powder makes it possible to form easily the anisotropic(especially radial anisotrotropic)super-thin ring or block magnets in complex shapes.The products can be formed in a unit together with other components.This process provides high precision and high acceptable rate of products.

Usages:

1. The compression molding magnets, as for simple mould and high magnetic properties, are widely used in stepping motor, CD-ROM spindle motor, general motor, vibrating motor, pick-up, HDD spindle motor, and FDD spindle motor.

2. The injection molding magnets, as for complex mould, magnetic properties around 6 to 7 MGOe, and highly consistency, are widely used in electric expansion valve, air-condition motor etc,.

Black Epoxy Coating Bonded Arc Magnet for DC Planetary Gear Motor

Advantages Of Compression Bonded Magnets

1: Higher magnetic strength than injection molded magnet.

2: High corrosion resistance (Epoxy coating, parylene coating) and temperature resistance, the salt spray teasting >72 hours

3: Magnetizing with complex patterns (Multi-poles on OD, ID, end face (axial), radial, helical magnetization......)

4: Higher magnetic property (Br: 3500-8000G, BHmax: 3-12MGOe, Hcj: 4000-17000 Oe

5: Complicated shape

1: Simulation calculation as to magnetic systems
2: Tool construction
3: Measuring of magnetic properties
4: Testing of the magnetic material
5: Customer support from an idea to post-marketing activities

Our Measurement Capability

—The magnetic performance (magnetic flux, magnetic field strength, pole angle, magnetic declination and the magnetic property(Br,Hcj,Hcb,BH) of magnetic material are one of primary parameter for a magnetic rotors, so the professional and exact measure will be required during magnet design and manufacturing.

Measuring Tool
1.Gaussmeter,it's for magnetic strength measurement
2.Fluxmeter,it's for magnetic flux measurement
3.Multi-magnetic poles scanner,it's for magnetic strength and pole angle measurement
4.Gaussmeter probes
5.Helmholtz coil
6.Magnetic declination tester
7.Hysteresigraph tester,it's for magnetic material grade measurement(Br,Hcj,Hcb,BH)
