Bonded
NdFeB 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 maget
may be formed into magnetic
components of relatively complicated
shapes. Also,it features single-time
molding and multi-pole orientation.
The injection molded magnet has a
high mechanical strength and may be
molded together with other matching
parts.
One of
the greatest advantages of the
injection molding process is that a
high degree of shape complexity is
possible — ie. gears, snap fits and
undercuts. It is also possible to
incorporate shafts, bushes and other
inserts into the process,
simplifying the magnetic assembly
manufacturing process
.
