Injection Molded Ferrite Is Widely Used In Pump Motor Rotors

What does Xinheng offer to customers?

Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding,Injection molded ferrite.

What's the feature of ceramic strontium ferrite magnet made by wet compression molding?

• Composition - Contain strontium ferrite (SrFe12O19) as the primary magnetic material. Strontium ferrite has good magnetic properties and is inexpensive to produce.

• Density - Have a high relative density of around 95% or more after sintering. This gives good mechanical strength.

• An-isotropy - Exhibit strong magnetocrystalline an-isotropy due to their hexagonal crystal structure. This results in a preferred direction of magnetization along one axis.

• Particle shape - The strontium ferrite powder used typically has a hexagonal platelet morphology which helps promote magnetic an-isotropy during molding and sintering.

• Molding method - The powder is mixed with a liquid binder and compression molded into a dense green compact using high pressures. This orients the an-isotropic particles.

• Firing process - The compact is then sintered at high temperature to develop density while preserving the induced magnetic anisotropy orientation from molding.

• Remanence - Have a maximum magnetic flux density or remanence along the axis of anisotropy, but little/no remanence perpendicular to it.

• Coercivity - Usually have medium to high coercivity depending on additives, density, and anisotropy level achieved.

What's the key advantages of ferrite magnets made by Injection?

• High design flexibility: Injection molding allows for the production of complex shapes and intricate patterns, expanding the range of applications for ferrite magnets.

• Improved performance: Injection-molded ferrite magnets can be designed to have higher magnetic properties and improved energy products compared to traditionally pressed and sintered magnets.

• Cost-effective manufacturing process: Injection molding reduces material waste and requires less labor compared to other manufacturing methods, leading to lower production costs.

• Consistent quality: Injection molding allows for the production of magnets with precise dimensions and uniform magnetic properties, ensuring consistent performance across all units.

• Enhanced durability: The injection molding process can create magnets with improved mechanical strength and resistance to demagnetization, making them suitable for demanding applications.
