Ferrite Magnet is widely used in many industries such as automobile and home appliance etc. It plays an important role as a key component in the motors. But do you know how the ferrite magnet is made? This article will make a clear description of the ferrite magnet manufacturing process.

1. The whole flow chart of the ferrite magnet manufacturing process.

         First of all, we need to get a glimpse of the whole flow chart of the ferrite magnet production process.

2. Weighing

         The weighing is the first step of the manufacturing process. Different type of ferrite magnet needs different categories or different proportion or the raw materials. The materials of the permanent ferrite magnet often include the Fe2O3, BaCO3 and SrCO3 etc.  This step needs to weigh the accurate quantity in strict accordance with relevant formula. Otherwise, we will not get right finished products.

3. Mixing

         After we weigh the right quantity of the raw material, the next step is to mix these raw materials as fully as possible. We need to get the homogeneous mixture for next steps.

4. Pelletizing

         The mixture will be put in the pelletizer, and some solution will be sprayed to the mixture during the process. The purpose of the pelletizing is to get fullly solid-phase reaction during the sintering. Besides, the size of the pelletized material will also influence the sintering time.

5. Pre-sintering

Pre-sintering is the first most important step during the ferrite magnet manufacturing process. The solid-phase raw materials will react hereby and will react into ferrite phase. This step will also help improve plasticity, contractility and density of the ferrite material.

6.Crushing

After the pre-sintering step, the pelletized material will be crushed into powder in this step. This step divides into coarse crushing and fine crushing. The particle size depends on the magnet property requirement. The crushing equipment is ball mill while the medium is steel ball and water.

7. Moulding

There are drying processing and wet processing for the moulding step, while there are also isotropic and anisotropic for the ferrite magnet type. So the moulding is the second important step for the process to get the right product. We need to highly control the mould and moulding technology to reduce defect rate.

8. Sintering

        The sintering step is the third most important step for the ferrite magnet manufacturing process. This step will affect the ferrite magnet’s microstructure and properties. The microdefects such as crack and bubble often appear during this step if operated wrongly.

9. Maching.

We will use right methods to make sure the size,the surface and the coating of the ferrite magnet meet customers’ requirements. These methods includes grinding, polishing, cutting, punching and coating technology.

10. Magnetizing

The magnetizing step is the last step for the ferrite magnet manufacturing process. The magnetizing should be done from the right direction according to the customers’ request.

11. Inspection and Packing

After all manufacturing steps are done, we will make the last inspection and make sure all the sizes and properties are in strict accordance with the contracts. Then the finished products will be packaged and sent to customers by different kinds of logistics.
