PLAMAX ferrite compound for injection magnets are composed of a ferrite
powder mixture with polymer bonding.
These materials can be either isotropic or anisotropic. As well as the low cost
and wide availability of raw materials, they offer good mechanical properties,
high edge strength and the advantage that they can be molded to almost any
shape with close tolerances.
Using insert and composite techniques, injection molding makes it possible to
connect magnets directly to shafts or other components, offering new and
cost-effective solutions in design and manufacture
