Injection Ferrite magnets

We will send the quotation to you within 24 hours.
Injection Ferrite Magnets  also called plastic 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.


Complex shape 

High precision

Multi pole magnetizing 

Not easy cracked with plasticity

Injection mould processing

Can be overmoulding on shaft or plastics
