Bonded magnet is made
through "compression
molding" or "injection
molding" of the mixture of
quick-quenched NdFeB
magnetic powder and bonding
agent. Due to its high
accuracy in size, the bonded
magnet may be formed into
magnetic components of
relatively complicated
shapes. The injection molded
magnet has a high mechanical
strength and may be molded
together with other matching
parts. In all it is produced
with high efficiency,
stability and repeatability;
Magnet and other part may
form together in one step;
Free choice of magnetizing
direction-especially for
multi-polar applications;
High dimensional
accuracy-large quantity
applications with minimum
post-press machining;
Thin-wall ring and complex
shape magnets; High
resistance to corrosion.
Usually, there are bonded
NdFeB magnet and bonded SmCo.
