The packaging methods of neodymium magnets are dependent upon the magnet size and the customer requirement. At the same time, international transportation of rare earth magnets is carried out by cargo ships and airplanes. Especially for air transportation, strong magnetism can interfere with navigation, electronic equipment, and control signals on the aircraft. Therefore ordinary packaging is not suitable for strong magnets.
1. How Can We Make a Qualified Magnet Package For Air Transportation？
In order to pass the inspection required by IATA DGR, we need to do some special treatment for the magnet package. We ensure that the magnetic fields of strongly magnetic materials and assemblies are well shielded. At present, the iron sheet is the main packaging material used for magnetic separation.
There must be a gap between the iron sheet and the magnet. And here can be filled with foam as support.
For larger-size magnets, it is difficult to reach total shielding requirements only by a single layer of shielding material. We have two other ways to solve this problem.
One is increasing the thickness of the iron plate or more iron sheets.
The other is the combination of shielding, putting one shielding into another shielding, leaving a certain gap between them.
2. How Can We Make a Qualified Magnet Package For Air Transportation?
Compared to airfreight packaging, the requirements for shipping magnets by sea are relatively simple. Of course, anti-magnetic packaging is still necessary, but the requirements are not as high as air freight packaging. They do not need to do a special magnetic inspection. In addition, ocean freight requires plastic wrapping around the outer box for waterproofing.
GME can provide wooden pallets for ocean freight magnets, they are a better choice because powerful permanent magnets can be packed more securely this way.
