Cup Magnet Assemblies
Generally our magnetic cup is composed of an outer round cup steel and a ring ceramic magnets
inside with a hole in the centre, which has been broadly applied
into holding, fastening and handing obejects, or used in some home
The inner magnet of cup magnets could form a special magnetic
circle with the the housing steel when putting it on an ferrous
material surface, which is much be strongger than the the magnet
self can do. At the same time, the outer cup steel can prevent the
inside magnets from damaged or crushed. In some of applications, it
can be filled with Epoxy between the cup steel and the magnet to
stop some iron dust adsorbed into the gap. Or it will reduce the
magnetic force of this round base magnet after several using.
Also if you need the holding force better, you can change the
ferrite magnet into ndfeb magnets.
