Product Name:Square with a circle inside NdFeB magnets



There are three main methods of pressing the powder – axial and transverse pressing. Die pressing requires tooling to make a cavity that is slightly larger than the required shape (because sintering causes shrinkage of the magnet). The Neodymium powder enters the die cavity from the hopper and is then compacted in the presence of an externally applied magnetic field. The external field is either applied parallel to the compacting force (this axial pressing is not so common) or perpendicular to the direction of compaction (this is called transverse pressing). Transverse pressing gives higher magnetic properties for the NdFeB.
