1, More Direct Information of Ferrite Disc Adhesive Double Side Magnet

1.1 The types of magnet we can supply

Ferrite magnets have good anti-corrosion performance, no surface coating treatment needed. Ferrite is a kind of a ferromagnetic metal oxide. The electrical properties, the resistivity of the ferrite is higher than metal, alloy magnetic materials, and they have a high dielectric properties. Ferrite magnet also reflected in the high frequency with high magnetic permeability. Thus, high-frequency ferrite weak areas have become widely used non-metallic magnetic materials. They are widely applied in speakers, cars, water pumps, disk drivers, starting motors, and electronic products.

1.7 Manufacture Process

1.Dry process: By dry process, can produce isotropic & anisotropic magnets;the tool can be changed and developed easily.
2.Wet process: By wet process, only anisotropic magnets can be produced;it is complicated to change the tool and the tooling charge is much higher

1.8 Detailed Four Step Quality Control

STEP 1: After the mould comes out. Test the size, tolerance and the property (BH(max), Br, Hcj, Hcb) of the mould, only the qualified products turn to next step.

STEP 2: After grinding, inspect the size and tolerance of the magnet with precision, only the qualified products turn to next step.

STEP 3: After cutting the thickness, examine the tolerance of thickness, guass and pull force, only the qualified products turn to next step.

STEP 4: Recheck the size and tolerance, surface of the magnet, exclude the unqualified (damaged, bad coating) pieces, then come to magnetizing and packaging.
