Permanent magnetic universal block, which means that it has undergone some processing steps, its size is more regular and its surface smoother than the original blank. 

However, all processes such as magnetization and fine coating have not been completed, so it cannot be used as a final product. We can customize universal blocks of certain specifications according to customer needs.

Grinding: Grinding the material is a preliminary surface treatment process, which is mainly used to remove the unevenness and burrs that may exist on the surface of the blank, making its size more regular and facilitating more accurate measurement of its size and other parameters.

Compared with the finished product: Compared with the finished product, the permanent magnet finished product has undergone a series of complete processing processes such as magnetization, coating, and finer grinding, while the permanent magnet universal block is still in a relatively "semi-finished" state.

Flexibility: The permanent magnet universal block is between the blank and the finished permanent magnet. Users can decide whether and how to magnetize (such as magnetization direction, magnetization intensity, etc.) according to their needs. This provides a more suitable option for users with specific needs.
