NdFeB magnet – bonded, pressed
Plastic-bonded NdFeB-magnets are formed into tools by means of compressing a mixture made of NdFeB-powder and synthetic resin. Bonded pressed magnets are able to fabricate in complex shapes. The magnetic values of bonded pressed magnets are higher than injected moulded magnets, due to their high density level. 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. Due to the high content of NdFeB powder, an epoxy coating is recommended.
