◇Injection plastic (Bond) Magnet
Plastic magnet of SEIKO PRECISION INC. has a highly controlled magnetic characteristic, generated
by integration between know-how of precision mold designing ,manufacturing technique and magnetic field analysis technology. The magnet is being applied to the actuator for clock movement and camera shutter in large quantity in our company.
【Characteristic】
Minimum dimension：
approx. φ2~, t=1.2~(mm)
Shape：
Cylinder・Ring・Rectangular parallelepiped、Oval、Sheet、
Tegular, etc.
Material：
Isotropic Ferrite, Isotropic NdFeB、anisotropic SmFeN、
Anisotropic SmCo, etc.
approx4kJ/m3~127kJ/m3(0.5MGOe～16MGOe)
□ The most appropriate material and magnetic specification
can be selected depending on application.
□ Both Isotropic and anisotropic magnet are available.
□ High flexibility of shape and design of magnet on account of
injection molding. Good for complex and precise designs.
□ Compared with sintered magnet, lighter and more impact-resistant
more crack-resistant.
□ Characteristic of magnet can be seen in advance by Magnetic
field simulation.
Applications - a variety of magnetic sensors
- Precision motor and actuator
- Printer head
- others
