After a long time of use, will the magnetic force weaken, how to maintain?

Shutter magnets

The Shutter magnets may indeed weaken their magnetic force after prolonged use, mainly due to the following factors:

1、Effect of high temperature: The temperature resistance of NdFeB magnet is usually about 80℃. If it is in a higher temperature environment for a long time, it may lead to a weakened magnetic force.

 

2、Material problems: If the magnet material contains more impurities, or uses low-quality materials, it may lead to insufficient magnetic force, and even degaussing in a short period of time.

 

3、Physical impact: High frequency of impact or impact may cause the magnet structural demagnetization.

 

4、High magnetic field environment: In a high magnetic field environment, the magnet may lose its magnetism or the magnetic pole changes (e. g., in the magnetic charging machine or demagnetic machine).

 

 

Therefore, in order to maintain the fast disconnecting magnet, extend its service life and maintain its magnetic force, the following measures can be taken:

1、Avoid high temperature: try to avoid exposing magnets to a high temperature environment, especially in high temperature operations such as injection molding, hot pressing or oven baking.

2、Choose high quality materials: When buying magnets, choose reputable suppliers and ensure that high quality materials such as N35 or higher nedFeB magnets are used.

3、Avoid physical impact: Avoid high frequency impact during transportation and use.

4、Regular inspection: check the magnetic force of the magnet regularly. If the magnetic force is found to weaken, replace it in time or take measures for maintenance. 

5、Use lubricant: For the cam structure of the quick removal magnet, the regular addition of grease can reduce wear and maintain its good working condition.

6、Correct installation: ensure that the quick removal magnet is installed correctly to avoid magnetic weakening or damage caused by improper installation.
