Ferrite Magnet Production Process
Raw Material Mixing and Pre-sintering
After mixing the raw materials, they are pre-sintered at high temperature to produce a ferrite precursor.
Molding and Sintering
The powder is compacted and then sintered at high temperature to form a dense magnet.
Processing and Magnetization
After processing, the finished product is magnetized and, after passing inspection, packaged and shipped.

Does ferrite need coating?
Ferrite Magnets do not normally require coating, but in certain applications coating may be selected to enhance performance or extend service life.
Special cases may require coating:
| Application Environment | Coating purpose | Common coating types |
| Humid or high-salt environments (such as the seaside) | Enhanced moisture and salt spray corrosion resistance | Epoxy resin, paint, sealant |
| Precision electronic components or packaging requirements | Prevent magnetic powder from falling off and improve insulation | Organic coating, epoxy coating |
| Aesthetics or logo needs | Improve appearance or facilitate identification | Painting, silk screen printing, label lamination |
| Secondary bonding or encapsulation applications | Improve compatibility with glue or materials | Primer treatment or special surface modification |
