plastic-bonded magnets

properties of plastic-bonded magnets

Plastic-bonded magnets are suitable for multi-pole magnetisation and their temperature resistance reaches up to 180°C. The temperature resistance of plastic-bonded magnets is limited by the binder used. They can be manufactured in isotropic as well as anisotropic qualities and have a high corrosion resistance. If used in environments with a risk of inducing corrosion in the magnet, it is recommended to use protective coatings – usually epoxy resin. Plastic-bonded magnets can take almost any shape. Plastic-bonded magnets are used in small motors but also in probes and sensors, above all in the automotive industry (IATF 16949).

we focus on

• supply of magnets for sensors and transducers
• supply of magnets to the automotive industry (IATF 16949)
• development of new applications with plastic-bonded magnets

manufacturing technology for plastic-bonded magnets

The manufacture of these permanent magnets requires very true-to-size forms, ensuring there is no need to further process the magnet; however, at the same time, they increase the costs of the first production batch. There are two basic technologies.

• injected plastic-bonded magnets – they are used for small but complex parts
• pressed plastic-bonded magnets – they have higher remanent induction
