Permanent Magnet Ferrite Manufacturers Produce Products With High Coercive Force

 

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

 

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

  • High magnetic performance: These magnets have high coercivity and remanence, making them suitable for high-performance applications.

  • Complex shapes: Wet compression molding allows for the production of magnets in complex shapes, which can be difficult to achieve with other manufacturing methods.

  • Excellent dimensional control: The process allows for precise control over the dimensions and tolerances of the magnets, ensuring consistent performance.

  • Cost-effective manufacturing: Wet compression molding is a cost-effective method for producing large quantities of ceramic strontium ferrite magnets.

  • Environmental benefits: The process produces minimal waste and can be done with water-based materials, making it more environmentally friendly than other manufacturing methods.

 

 

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.​​

Introduction Of inverter Motor:

Variable frequency motor is a kind of motor that can adjust the speed by changing the frequency of the power supply. It is usually used in conjunction with the inverter, by adjusting the output frequency of the inverter, you can change the speed of the motor, to achieve energy saving, accurate control, reduce noise and other effects. Variable frequency motors are widely used in industrial production lines, air conditioners, fans, pumps, compressors and other equipment to meet different work needs.
