The existing bonding process for magnetic components almost always uses a glue coating process, i.e. a layer of glue is first applied to the bonding surface of the product, and then the two magnets are pressed together tightly using external forces or the attractive force of the magnet itself.
However, when bonding small magnets together one by one, the gap between the magnets is difficult to control evenly, which may cause a gap that is too large or too small, and the glue cannot achieve the best bonding performance. The final product will fail to meet the usage requirements and be scrapped.
At present, many manufacturers use glass beads to control the consistency of the gap, but this increases the complexity of making laminated magnets.
