Description
BN-8 Bonded Neodymium Magnet

Custom-Made Bonded Neodymium Magnet

 

UNMAG understand that some projects and patented applications often require a unique size or shape.

We can manufacture Bonded NdFeB magnets to your exact specifications in just a few weeks in prototype or

production quantities,

Advice from our team of expert technicians is available as they are always on hand to help and will always

operate confidentially.Whatever the application, a dedicated member of our technical team will

discuss your requirements with you in full with a view to understanding your application inside and out

before we proceed to manufacture the product to your desired specifications.

 

There are some things to consider before designing a custom-made Bonded NdFeB magnet:

1.Which material do you require the magnet to be made from?

We can manufacture bespoke sizes in all grades of neodymium, samarium cobalt, ferrite, alnico and flexible material.

2.What size do you require?

To be able to provide a quotation we would need to know the exact dimensions as a minimum,

preferably supplied on a technical drawing.

3.Where will the poles be positioned?

We can produce magnets and assemblies with axial, diametric, radial or multi-pole magnetisation.

4.Will the magnet require a protective coating?

We can offer a wide range of coatings to meet almost any demand.

5.How many units do you require?

It is more cost-effective to produce magnets in larger quantities; however, it is possible to produce

most options in small batches

6.What's lead time you need?

According to your quantity and urgent requirement of delivery time,We will adjust production scheduel to meet your

delivery time.
