Product
Versatile range of shapes
Injected, plastic-bonded SmFeN magnets can take almost any shape, exhibiting a certain degree of flexibility. However, this is not comparable with purely injected plastics without ferrite content. Thanks to the production method – injection molding – very high shape tolerances can be achieved. This can eliminate the need for additional processing steps. Moreover, it is possible to combine the magnets with insert parts in the same process step and create complex components – simplifying subsequent assembly.

General
Many geometries and levels of magnetization possible
Plastic-bonded SmFeN magnets have a much higher magnetic performance than hard ferrites. As a result, the complete system configuration can be much smaller. With an equally complex range of shape options, they are mechanically resilient and almost any magnetization level can be chosen. SmFeN magnets are corrosion-resistant and have very low aging at high temperatures.

PRODUCTION PROCESS
All of the advantages of injection molding
Plastic-bonded SmFeN magnets, created through the injection molding process, combine all the benefits of pure plastic injection molding with the fourth dimension – magnetism.
Note
The resistance to acids and alkalis depends on the plastic used. This needs to be checked for each specific application. Rare-earth magnets must be magnetized after the injection molding process using suitable magnetizing coils.
TECHNICAL DATA
What the plastic-bonded, injected SmFeN magnet can do
The high-performance rare-earth magnets are elastic, exhibit high shape tolerances and can be prepared with insert parts for assemblies. They feature minimal aging at temperature and are corrosion-resistant.
