Gasbarre Products Builds the First Magnet Powder Presses to Produce Neodymium
Permanent Magnets in the United States
The global permanent
magnet market
is expected to grow
by 9.5 % CAGR
from 2021 to 2026.
This growth is fueled
by consumer
electronics, in applications
such as
smartphones, sensors,
computers,
loudspeakers, etc.
Of course, the high
demand for electric
vehicles (EVs) and
green technologies
is expected to augment
this growth
substantially as
well.
With high magnet
costs imposed
by China, the
United States is
being forced to
start its production
Gasbarre Products offers a full range of industrial custom presses
designed to take on a full range of applications. Gasbarre has
developed a new range of magnet powder compaction equipment
for the development, processing, and production of rare-earth
magnets.
" For over 50 years Gasbarre has made
the best powder compaction presses
in the world. We are proud to be a part
of building the critical rare earth supply
chain in the United States through our
line of rare earth magnetic presses. We
are heavily invested in supporting this
fast-growing segment and look forward
to establishing strong partnerships with
our current and future customers there, "

First Gasbarre magnet powder press
of rare-earth magnets demanding the use of different equipment
to manufacture them for different applications and technologies.
Within the magnet manufacturing process, there is an important
process that requires compacting or pressing the magnet powder to
get the final magnets. For this process the use of powerful magnet
powder presses is necessary. The magnet pressing process allows
the production of magnets with specific shapes and sizes, making
them highly customizable for different purposes and applications.
The process of pressing magnet powder into magnets involves
compressing the fine particles of magnet powder together, typically
using a hydraulic press, and applying a uniform magnetic field to
align the powder particles in the non-magnetic cavity region during
the compacting process. The pressed magnets can then be further
processed to achieve desired magnetic characteristics such as
increased coercivity or improved temperature stability for many applications.
One advantage of pressing magnet powder into magnets
is its cost-effectiveness. In addition, pressing magnet powder
requires fewer steps and less energy, making it a more economical
and efficient option for magnet production. Additionally, this method
allows for mass production, ensuring a steady supply of magnets
at an affordable price. Furthermore, pressing magnet powder into
magnets offers greater design flexibility. The ability to shape the
magnet according to specific requirements makes it suitable for
various industries such as automotive, electronics, aerospace, and
renewable energy. For example, pressed magnets can be tailored
to fit intricate spaces within electronic devices or used in permanent
magnet motors for EVs to enhance their efficiency. This magnet
manufacturing process enables the production of customized
magnets with enhanced properties suitable for diverse applications.
As technology continues to advance, pressing magnet powder will
likely remain an essential method in creating high-quality and efficient
magnetic products.
Gasbarre Products with consultancy support of " Salvador Consultant "
has designed, manufactured, and tested the first magnet powder
presses to produce neodymium magnets in the United States.
The Gasbarre magnet presses were designed, built, and tested in
DuBois, Pennsylvania. The magnet presses were designed for the
pressing process of neodymium magnet powder under a uniform
magnetic field. These magnet presses will be employed to produce
sintered neodymium magnets for the US industry. For more information
related to the production of rare-earth magnets in the US,
please consult the September/October 2023 Magnetics Magazine
issue.

magnet presses were designed and
equipped with electromagnets with optimized
pole caps to produce high magnetic
fields in the powder cavities. The magnetic
structures of the magnet presses were designed
using a deep and wide knowledge
about magnetic materials, magnet materials,
and magnetic field production " .
The Gasbarre magnet presses can be
