bonDED FERRITE MAGNET

Injection bonded magnets offer a combination of high magnetic strength and excellent physical properties. They offer large scale manufacture of shaped parts of close dimensional and magnetic tolerances. As smaller more efficient designs are therefore available then with increased design freedom lower losses of magnetism can be achieved.

Typical tolerances will depend largely on the part configuration and the type of tooling selected. Designers can consider standard tolerances of ±0.075mm. Tighter tolerances are available on request. Different binders are available including Nylon 6, 12, EEA and PPS. The material for any specification is chosen based on many factors for example temperature, strength, water absorption, solvent resistance, complexity of shape and compatibility with the magnet power.

The injection moulding process allows for moulding directly on, in or over other components thereby reducing secondary processing costs. This is called insert or overmoulding. Injection moulded magnets can be produced from very simple forms to quite complex arrangements in sizes up to 100gms. Further processing is rarely required but if necessary this can be achieved using conventional tools.

Permanent ferrite magnet is made of Sro or Bao and Fe2O3 by ceramic processing technology, now, we have 6 models of permanent magnet products, namely Y10T, Y20, Y25, Y30, Y30BH, Y35 and etc. The products include rings, disks, blocks, and segments.

The elements of Ferrite magnet are ferric oxide/barium, strontium. Ferrite has higher coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets. The biggest advantage of such magnet is their low cost. It is widely used from motors and loudspeaders to toys and craft etc.

Typical Applications

Magnet stators for fractional horsepower D.C. motors.

Multi-pole magnetic motors for brushless D.C. and stepper motors.

Magnetic actuators for magnetic switches and solenoids.

Sensors for activators and industrial applications.

Anisotropic injection magnet
Ferrite magnet is Made by means of powder metallurgy. Its chemical composition: Ba/Sro-Fe2O3.Hard to be de-magnetized, with good anti-corrosion property. The products are make in the shapes of circular, cylinder, square, tile-type. Widely used for magnetic electro-machinery, loudspeaker products, micro electro-machinery, household appliance, electronic acoustics equipment, copycat, magnetic motor equipment, culture and education tools and magnetic treatment equipment.
Hard Ferrite (ceramic) magnets, composed of barium or strontium, were developed in the early 1960's as an alternative to the more expensive metallic magnets.
This class of magnet is very hard, brittle and possesses lower energy characteristics compared to other magnetic materials. However, it is very popular and widely used because of its excellent resistance to demagnetizaion, corrosion, and the advantageous pricing.
Ferrite magnets are manufactured by pressing, sintering, or injection molding. These magnets can be both anisotropic and isotropic. Anisotropic grades are oriented in the manufacturing direction and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction.
