What does Xinheng offer to customers?
Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding.
What's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?
Low cost - Strontium ferrite is inexpensive and the wet molding process is relatively simple. This makes them cheaper than rare-earth magnets.
High magnetic property-Even without heavy rare earth element additions, strontium ferrite magnets can achieve coercivities of 700-1000 kA/m, making them suitable for many applications.
Dimensional consistency - The compression molding process allows for close dimensional tolerances and uniform magnet shapes to be produced consistently.
Temperature stability - Strontium ferrite magnets have high Curie temperatures, typically around 450-470°C. They maintain good magnetic properties over a wide operating temperature range.
Resistance to corrosion - Being fully dense ceramic materials, they are not prone to corrosion like bonded magnets containing additives.
Mass production capability - The molding process is amenable to automated high-volume manufacturing of complex magnet geometries.

What's the application of Xinheng's permanent ferrite magnets?
Xinheng mainly manufactures the following types of ceramic arc segment magnets:
How Xinheng fabricates its permanent strontium ferrite magnet?
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.

Introduction Of Universal Motor:
A universal motor is a type of electric motor that operates on both alternating current (AC) and direct current (DC). It is commonly used in household appliances such as vacuum cleaners, power tools, and kitchen appliances due to its ability to operate on different power sources.
The universal motor is designed with a wound rotor and a commutator, allowing it to be compatible with both AC and DC power supplies. Its versatility makes it a popular choice for applications that require variable speed and high power output.
