We have the fields under control

A magnet is only as good as the material and its magnetisation allow it to be.

We have already seen a lot in the course of the magnet years. The material is not always to blame if things don’t run smoothly. The magnetization or its preparation offers enough conflict potential to achieve a miserable result with a good material. Those involved often ask themselves what we have done wrong and look for explanations in the distance, which are actually so close. Even before a magnet is delivered, it must be checked whether the selected preferred magnetic direction is actually present and whether the precision of the design is given. With the help of measurements for angular deviations of the magnetic axis as well as north/south effect testing, errors can be detected in advance and avoided for series production.

But this alone is not enough. The preferred magnetic direction is already defined during the manufacturing process and only fully exploits the magnetic potential from the materials in the later application of the magnets, since all magnetic moments are already pre-defined for this magnetization. For this reason, the voltages applied to generate the preferred direction in the pressing systems must also be regularly checked and adjusted so that the magnetic potential can also be used to the full extent.

Some magnets are delivered fully magnetized ex works, while other applications require magnetization only after installation. Both options are equally served by us. It should be noted that magnetized products are subject to special safety regulations during transport and handling.

We would be pleased to advise you on the respective legal guidelines or also on the magnetizing tools, should you plan magnetization after final assembly.
