Bonded NdFeB magnets Plastic-bonded NdFeB-magnets are formed into tools by means of compressing a mixture made of NdFeB-powder and synthetic resin. The economical spray-form method is used. The magnetic values of these spray-form magnets are lower, however, due to their reduced density level when compared to those magnets manufactured using form-pressed tools. These magnets achieve highest form tolerances, making a further shaping process unnecessary. During manufacturing, general tolerance levels are kept to ±0.1 mm. The bonded NdFeB-magnets themselves have a relatively high corrosive resistance to environmental influences.
Advantages:
1.Produced with high efficiency, stability and repeatability.
2.Magnet and other part may form together in one step.
3.Free choice of magnetizing direction-especially for multi-polar applications.
4.High dimensional accuracy-large quantity applications with minimum post-press machining.
5.Thin-wall ring and complex shape magnets.
6.High resistance to corrosion.
