About the magnet with holes, there are many people want to know some questions. Today, I will make a summary of the topic to introduce, if there any others questions, welcome to contact our online customer service, we will be online for you to answer.
There are various shapes of neodymium magnets with holes in the figure below, which can be processed in small, large, and flat sizes;
Is the hole on the front and back of the hole magnet is same size?
This depends on what holes the customer needs , the current magnet mainly has countersunk hole and through hole. The through-hole means the front is as big as the back. The size of countersunk hole is one big and one small. If you want to see the sample display, you can search on the product page of our website.
Do magnets with holes and without holes have the same magnetic force?
Compared with those without holes, if the magnets of the same size, the force area with holes is reduced, so the magnetic force is small. The purpose of the drilling is to fix the assembly, to attach the magnet to another product. Recommended reading what are the differences between round magnet with hole and without hole?
The magnet with countersunk hole is mostly NdFeb, if the ferrite material can choose countersunk holes?
This is also no problem, you can see our products 16mm dia countersunk ferrite magnet ring 16x5mm hole 3mm
Can I choose to punch a hole on the side of a ring magnet?
No problem, this magnet belongs to the special-shaped magnet. It is easy to achieve with NdFeb material, ferrite is not easy to process.Our website also has this side punching strong magnet, for example, Strong contersunk neodymium magnet with side hole.
How many specifications can be achieved for the smallest circular magnet with holes?
In general, we can acheive D3 x d1 x 1mm. D is the outer diameter and d is the inner diameter.
How much is the price difference of magnet with hole without hole?
There is no really price for magnet customization. It depends on your magnet specification, performance, tolerance and processing difficulty.
How is the hole of the magnet made?
Magnet is powder metallurgy, punching needs special equipment, otherwise it is easy to break, we have professional punching equipment.
What screws are used for the perforated magnets?
It is recommended to use stainless steel screw and the anti-corrosion performance is better, depending on the aperture of your magnet.
The direction of magnetic induction of a magnet with holes?
Generally the thickness direction, of course, there are special, depending on your product design, you can communicate with the magnet manufacturer to ensure that it meets your needs.
What types of perforated magnets can you provide?
We can provide square magnet with holes, rectangular with holes, curved with holes, cylindrical magnet with holes, triangular with holes, circular with holes, and other special shapes, such as L-shaped magnet with holes. We can meet your needs, including the type and size of holes.
How many holes can be punched in a magnet?
Normally, there is no problem, common is 1, 2, 4, but there are also 8 holes processing, the more holes, the higher the cost.
The above is answering for you to sort out the related question about magnet with holes, if you need to purchase the magnet with holes, welcome to contact us to give you a quotation.
