To purchase magnets, please feel free to contact Karich Magnet Factory. Our main magnet products include neodymium iron boron shaped magnets, ferrite black magnets, injection molded ferrite magnets, bonded neodymium iron boron, motor magnetic tiles, etc. The specifications, shape, and performance can be processed and produced according to your requirements or drawings.

1. Is the front and back faces of the perforated magnet the same size?

This situation depends on what holes the customer needs. Currently, the main punching methods for magnets are countersunk holes and through holes. Through holes are the same size as the front and back sides, while countersunk holes are one end large and one end small, which is not very intuitive. It's okay. You can take a look at the product image catalog on our website to learn more.

2. Do magnets with and without holes have the same magnetic force?

Magnets of the same specification with small holes will have lower magnetic force than those without holes. The purpose of punching holes is to fix the assembly and assemble this magnet onto other products.

3. Most of them are made of neodymium iron boron with more sinking holes, can ferrite materials also be used?

This is also no problem. You can take a look at the ferrite perforated magnets with screw holes in our products

4. Is it also possible to punch a hole on the side of a circular magnet?

No problem, this type of magnet belongs to a special shape. It is easy to achieve using neodymium iron boron material, and the ferrite is relatively difficult to process, but it is also possible, such as this ring shaped ceramic ferrite magnet with three small holes.

5. What are the specifications of the smallest circular perforated magnet that can be achieved?

Generally, D3 * d1 * 1 can be achieved. The large D represents the outer diameter, and the small D represents the inner diameter.

6. What is the price difference between a magnet with holes and a magnet without holes?

There is no fixed price for customized magnets, which depends on your magnet specifications, performance, tolerances, and processing difficulty,
