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.
