Perforated Punched Magnets-1

Regarding the perforated (perforated) magnet, many people have some questions and want to know. Today I will simply make a special topic to introduce it. If you have any questions, please contact our online customer service.

 

1. Are the front and back faces of the magnet with holes the same size?
Depending on the situation, it depends on what holes the customer needs. At present, the main holes for magnets are countersunk holes and through holes. The through holes are the same size as the front and back. You can take a look at the product pictures on our website to understand.

 

2. Are the magnets with and without holes the same magnetic force?
For magnets of the same specification, those with small holes will have a smaller magnetic force than those without holes. The purpose of punching holes is to fix the assembly, and to assemble this magnet to other products.

 

3. Most of them are made of neodymium iron boron, and the ferrite material can also be used?
This is also no problem, you can refer to the product list.

 

4. Is it possible to make a hole on the side of a ring magnet?
No problem, this is a special-shaped magnet, which is easy to realize with NdFeB material, and ferrite is not easy to process.

 

5. What is the specification of the smallest round magnet with holes?
Generally, D3*d1*1 can be achieved. The big D is the outer diameter, and the small D is the inner diameter.

 

6. How much is the price difference between magnets with holes and magnets without holes?
There is no fixed price for magnet customization, which depends on your magnet specifications, performance, tolerance and processing difficulty.
