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.
