For those frequently exposed to permanent magnets, the common magnets are typically circular, disc-shaped, or square in regular types. The processing of irregular-shaped magnets is usually not standardized in terms of size and shape. These types of magnetic products generally require customized processing.

It is known that the main application areas of non-standard magnet processing are widely seen in various industrial fields such as machinery, motors, engines, instruments, etc. The commonly used materials for non-standard magnet processing are neodymium iron boron and ferrite, with wafer magnets being relatively common in the category of non-standard magnets. The common non-standard magnets include slotted magnets, stepped magnets, semi-circular magnets, and concave-convex magnets, among others.

Each type of custom-shaped magnet has a unique manufacturing process, as it depends on the detailed product specifications. The production time and cost for custom-shaped magnets are significantly higher than those for standard magnets. The material is brittle and the manufacturing process is complex, usually involving grinding and wire cutting techniques to shape the magnet. These methods alter the shape without affecting the magnet's original magnetic properties or causing demagnetization.
