Injection Ferrite magnets

Injection Ferrite Magnets  also called plastic ferrite magnets , are made of ferrite powder, plastics and other materials by injecting process, It  can be made complicated shapes magnets with precise sizes . It can be inserted in metal and plastic parts.

The precision tooling is necessary to ensure the products dimensional tolerance. The plastic magnetic material dimension would be change after cooling due to the thermoplastics shrinkage.


Characteristic

Complex shape 

High precision

Multi pole magnetizing 

Not easy cracked with plasticity

Injection mould processing

Can be overmoulding on shaft or plastics
