For each product, I believe everyone's first concern is the quality of its good or bad. So, the quality of the magnets is determined by what factors?
The first is the magnetic force, and the most fundamental factor in the measurement of magnetic force is Gaussian. However, one often overlooks one issue. The comparison of magnetic forces can only be limited to the comparison between the specifications and the same performance. Therefore, it can not be said that the higher the magnetic force, the better the quality.
Followed by tolerance. Every factory controls tolerances. And the size of this tolerance can reflect the quality of good or bad. So in the quality control, pay attention to whether the size of the negative tolerance to go more serious.
The last is the magnet surface treatment. Poor performance of the surface treatment of poor color degree, collapse collapse edge, lack of missing edge and so on.
