Aichi
Steel Corporation (Head office: Tokai-city, Aichi prefecture / President: Yuji Shibata)
will make available the press-forming technology of the world's strongest bond magnet
MAGFINE TM in May 2003.
Currently, only Aichi Steel has the technology to press-form bond magnets in magnetic
fields. The company will sell the original press-forming technology including its
dedicated press-line in one package to magnet or motor manufactures at home and abroad to
popularize the MAGFINE.
In April 2003, Aichi Steel used the MAGFINE to design and prototype a DC motor, which is
50 % lighter yet equal in cost compared with conventional models. The DC motor was
exhibited at the Motor Technology Show hosted by the Japan Management Association from
April 16 to 18 at Makuhari Messe, to publicize the breakthrough.
The MAGFINE is a neodymium-base anisotropic bond magnet with a magnetic property 25 MGOe
of the maximum energy product, which means its performance is over six times higher than
ferrite magnets; in addition, it is a thin-ring type, which is easy to design motors.
However, magnetic particles of the MAGFINE are able to include only about 15 percent of
resins at the time of press forming to secure high magnetic force. They also need to be
formed in magnetic fields to align their crystal orientation. Besides, they require a
high-level know-how mainly concerning forming techniques and mold design. For example,
magnetic molds with certain durability must be used. Aichi Steel has developed this
press-forming technology before anyone else in the world and has produced more than
100,000 units of MAGFINE per month.
The MAGFINE is expected to replace ferrite magnets and neodymium-base isotropic bond
magnets as a magnet for motors, with about 30,000 tons of the potential demand estimation.
Making this technology available will promote the establishment of MAGFINE's supply sites
all over the world, leading to market cultivation.
