If you have magnet problems, welcome to the FAQ column of Courage Magnet in Dongguan. At present, nearly 400 questions and answers about magnets have been collected, helping many netizens to solve their doubts. Today, what we bring to you is the introduction of common bad phenomena of magnets, including appearance, size, magnetic strength, magnetization, etc.
One, magnet undesirable phenomenon - appearance
The appearance defects are mainly absent, foaming, falling corners, knife marks, sandy eyes, linen, scratches, etc.
Two, magnet undesirable phenomenon - size
Dimensional defects such as the diameter or length of the magnet, width, thickness is large or small, not in the tolerance range, resulting in the product can not be installed, some products need positive tolerance, some need negative tolerance, this QC can be found when testing.
Three, magnet undesirable phenomenon - magnetism
Magnetic is not enough is one of the common adverse phenomena, suction will not lead to suction, this phenomenon may be the customer in the choice of magnet size and performance level of the problem, it may also be the magnet manufacturer wrong materials and other problems, usually can be improved by increasing the thickness of the magnet or improve the performance of the magnet grade.
Four, magnet adverse phenomenon - magnetization
The common bad magnetization is the reverse direction of magnetization, and magnetization is not saturated.
The above will introduce the magnet in the appearance, size, magnetic strength and magnetizing aspects of the adverse phenomenon are what, pay attention to us, take you to know more about magnets.
Go to the Courage magnet manufacturers magnet knowledges column to learn more about magnet problems.
