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 Magnet is an extremely powerful permanent magnet made from rare earth elements. It is usually shipped in containers and is very delicate. The following guidelines should be followed for packaging and shipping of sintered neodymium magnet:

  • The magnets should be packed in a sturdy box to protect them from external damage during transportation.
  • The box should be lined with a soft material to prevent the magnets from rubbing against each other.
  • It is important to make sure that the magnets do not come into contact with any metal objects, as this could cause them to become magnetized and potentially damage the magnets.
  • The package should be labeled with the words "FRAGILE - HANDLE WITH CARE" to ensure that the shipment is handled with the utmost care.
  • The package should also be marked with the words "MAGNETIC - KEEP AWAY FROM METALS" to ensure that the shipment does not come into contact with any metal objects during transportation.
