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. |

Packing and Shipping:
Packaging and Shipping of Sintered Neodymium Magnet
Sintered Neodymium Magnets are packaged using a variety of
materials designed to provide maximum protection against damage
during transit. Packaging materials can include bubble wrap, foam,
or corrugated cardboard. The magnets are also usually placed into a
box or other container, and then placed into a larger outer box.
This outer box is then taped securely to ensure the magnets are
protected from outside elements during transit.
Shipping methods for Sintered Neodymium Magnets typically involve
the use of a freight courier such as UPS, FedEx, or DHL. Depending
on the size and weight of the shipment, ground or air shipping can
be used. The shipping cost and transit time are usually determined
by the size and weight of the shipment, as well as the destination
of the shipment.
