Which Products Commonly Use Custom Special Shaped Magnets?
Magnets with complex shapes are commonly referred to as custom-shaped magnets. Due to the difficulty of manufacturing and processing them, not every manufacturer specializes in this field. MPCO Magnets is a manufacturer specializing in the production of custom-shaped magnets. We provide quotes and prototypes for custom-shaped magnets, as well as custom-made options such as offset-drilled magnets, convex charging magnets, side-drilled magnets, and slotted magnets. We welcome you to provide your own drawings or samples for custom manufacturing.
Which Products Commonly Use Custom Special Shaped Magnets
Today’s article focuses on the products in which custom-shaped magnets are most commonly used, as well as their applications and types.
Among the customers using custom-shaped magnets that we’ve encountered, magnetic connectors are a common application, as are car chargers. Of course, they’re also used in other fields such as electroacoustics, electrical appliances, consumer electronics, motors, and mobile communications. For example, in the drive motors of new energy vehicles, the rotor typically doesn’t simply use cylindrical magnets; instead, it employs arc-shaped neodymium-iron-boron magnets. This design better fits the rotor’s structure, resulting in higher magnetic flux utilization and improved motor efficiency. In TWS Bluetooth earbuds, ultra-thin custom-shaped neodymium magnets are frequently used, with some as thin as 0.3mm to 0.5mm, and they often require special chamfering and custom edge trimming.

Why do many customers choose to use custom-shaped magnets, which are more expensive?
The main reason is to better fit the internal structure of the product and avoid wasting space. Magnets with holes, slots, or positioning features are easier to install. In motors, custom-shaped magnets (arc-shaped, fan-shaped, or bread-shaped) can improve torque, efficiency, and operational stability.
As for types, the current mainstream material is sintered neodymium-iron-boron. Other materials, such as sintered ferrite, injection-molded ferrite, and samarium-cobalt, can also be processed into custom shapes according to customer requirements.
