Bonded Ferrite Powder

Commercial used permanent magnetic ferrite is strontium ferrite and ferroxdure whose component are SrFe12O19 and BaFe12O19 respectively. It features perfect magnetism and cost performance ratio. It is the largest magnetic functional material and is widely used in the motors, microphone and magnetic adhesive material. A great deal of this kind of materials are used in autos, motorcycles, radios, microwave ovens, refrigerators, magnetic plant, medicare devices, CPE, office appliances and kids toys. Qualified standard of sintered preburning material and its magnetic powder：

2. Procedure Summaries

  • Before production,the powders should avoid being humidified, and avoid being mixed with other material and impurity.
  • The mixture ratio of binders and plasticizers should be defined according to the grade of the powder.The powder and binders and plasticizers should be mixed uniformly.
  • The working temperature of extruding should be controlled between 50O℃ to 90O℃ .(calendaring plate is usually between 80OC to 120O℃ )
  • Please adjust the extruding speed,calendering speed and times,according to the property required.
