Bonded ferrite powders are the main
raw materials for producing bonded ferrite magnets, The
high-property powders are suitable for extruding, rolling or
injecting process Specifications of XCF
Plastic Bonded Ferrite Magnetic Materials
XCF series Strontium plastic bonded ferrite magnetic powders are
suitable for making various bonded magnets. They have good
compatibility with different kinds of composite size, such
powders have high filling capacity. They can be used for making
different kinds of magnets by extrusion or injection molding.
The magnetic ferrite powder are
suitable for producing different grades of hard ferrite magnets
by wet pressing or dry pressing. We supply the magnetic ferrite
powders in three forms: granular powder (6-12mm), coarse powder
(3-6um), fine powder (0.75-1.05um) according to the needs of
clients. The magnetic ferrite powder can be classified as
isotropic magnetic ferrite powder and anisotropic magnetic
ferrite powder. Anisotropic magnetic ferrite powder has better
orientation. |

2. Procedure
Summaries
a. Before production, the powders should avoid being humidified, and avoid
being mixed with other material and impurity.
b. 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.
c. The working temperature of extruding should be controlled between
50OC to 90OC.(calendaring plate is usually between 80OC to 120OC)
d. Please adjust the extruding speed, calendaring speed and
times, according to the property required.
