Manufacturing process for magnets (outline):
| Mixing | 1.Mix the ingredients. |
| Melting | 2.Dissolve the mixture at high temperature and prepare an alloy. |
| Fine pulverization | 3.Turn the alloy into fine powder. |
| Molding in a magnetic field | 4.When pressing the fine powder, apply a magnetic field to it and
prepare
a molded product of powder with aligned directions of
magnetization. |
| Sintering and heat treatment | 5.Sinter the product at about 1,100℃, and then subject it to heat
treatment at
about 600℃ to increase its magnetic characteristics. |
| Processing | 6.Process the manufactured magnet base material and finish it into
the product shape. |
| Surface treatment | 7.Subject the product to surface treatment in order to make it
rustproof. |
| Magnetization | 8.Apply a magnetic field to give the magnet magnetism. |
