The products has rigid, elasticity , with metal, plastic and other inserts molding, simplify assembly, to make sure precision. Hot melt state full of cavity, one model with more pieces, uniform density, good magnetic field consistency, plastic good coating ensures the corrosion resistance of the product.
the corrosion resistance of the product, it is easy to produce precision magnet with complicated shape, and the subsequent assembly is not easy to crack.
II. Features :
A variety of shapes can be manufactured, such as cylinder, arcs, rings and many other complicated shapes; without further sintering and mechanical processing.
- Diverse magnetization, multi-pole magnetization and screw angle magnetization are available, and the field distribution could be square, sinusoid, etc.
- Higher magnetic property, the magnetic property of bonded magnet is between that of sintered NdFeb and Ferrite, with good consistency and stability.
- Good corrosion resistance, after ED coating or through some special treatment, the magnet can be used under normal or unfavorable environment conditions for a long time.
IV : Application :
