2. Product Consistency:

3. Magneric Polarity Distribution:

♦ Magnetic Polarity Distribution has been an important aspect when magnet is installed into sensor application. Theoretically, the North and south poles should been evenly distributed on the magnet surface no matter the direction it was magnetized. On the other hand, the reality is quite the opposite, illustrations have been demonstrated below.

4.Magnetizing Orientation and Dimensions:

5. Research and Development:

• Controlling the Strip Casting

•  Thickness of Striped Fragments

•  Growth of Cylindrical Crystal

•  Consistency of Fragment Thickness

  Controlling over thickness of striped fragments the level of α–Fe can be eliminated with the appropriated cooling process. Raised  α–Fe particles would fluctuate the stability,consistency and many other important aspects of the magnet from the very beginning of the production process.

• Controlling over Jet Milling

Controlling the pressure, Jet Milling turning speed and powder feeding speed at the appropriate level will centralize the powder particles distribution.

Using this technique improves the average size of each particle with the goal to make them identical.

Having a consistent size of magnetic powder is required for coercive force and corrosive resistance.

Similar size of powder leads to similar microchip during Sintering process. 5-10 μm is considered to be industrial standard in China.

In Newland , we presume 5-7 μm is considered to be industrial standard in China. In Newland ,we presume 5-7μm in average size.

• Controlling Over Low Oxygen:

Oxygen produces oxidizes within the rare earth material. Controlling the oxygen level is important keeping it at extremely low levels ideally below 200ppm is required in order to produce stabilized high grade magnets.
