Sintered NdFEB Magnet Production Processes

The sintered NdFEB magnet is manufactured by utilizing the powder metallurgy method. Its production is a systematic project that sets down with a superior foundation. Here are the principal processes for sintered NdFEB magnet production.

1. Raw Materials

Selecting the right raw materials is the fundamental point for high-quality sintered NdFEB magnet production.

2. Composition Designs

It determines whether the magnet’s quality and performance can meet the customer’s requirements. 

3. Smelting

It is the beginning process for sintered NdFEB magnet to undertake the manufacturing processes. This process goes on for hours to be accomplished and needs furnace temperature to reach about 1300°.

4. Powder Milling

This process aims at crushing large alloy ingots into certain size powders. In obtaining well-oriented magnets, it is necessary that powered particles must have small dimensions and concentrated distribution size.

5. Orientation

One of the essential technologies for manufacturing high-performance sintered NdFEB magnet. This is done after the crushed magnetic powder is placed into the mold. There is an external magnetic field that applies for orientation and leads the magnetic powder to be compacted after. 

6. Sintering and Tempering

This process is taken on to further optimize the structure of sintered NdFEB magnet that improves and increases its density strength, magnetic properties, and performance. 

7. Machining

The machining process is capable of producing magnetic materials in certain shapes and sizes according to customers’ needs. Moreover, the machining process comes in three different types, including:

  • Cutting Processing. A machining process that cuts square columns and cylindrical magnets into disc-shaped and square-shaped elements. 
  • Shape Processing. It processed square and round magnets into tile-shaped, fan-shaped or other complex-shaped magnets. 
  • Punching Processing. That makes the square and round bar magnets turn into cylindrical or square cylindrical magnets.

8. Surface Treatment

The final stage for the sintered NdFEB magnet of the production process. It is a process where different coating material is applied to magnet surfaces which is beneficial for providing extra durability, appearance enhancement, and resistance against rust, corrosion, and wear.
