Product Description

Injection molding uses a solid binder (e.g. a plastic or thermosetting epoxy) plus the magnetic material but gives a greater variety of shapes and complexity of shapes compared to compression bonded. The end material is isotropic – the magnetising coil fixture design determines the magnetic pattern it takes.
Overmolding is possible with injection molding process.
Injection molded magnets are produced in tens or hundreds of thousands of magnets per production run.

Advantages of Permanent Injection molded ndfeb magnets

• More complex shapes are possible
• Overmold, insert mold, etc all possible
• NdFeB, SmCo, Alnico and Ferrite versions possible
• Hybrid versions as well (e.g. Ferrite+NdFeB) with combined properties
• Low electrical conductivity, low eddy currents
• Good tolerances. More resistant to chipping than compression bonded

Disadvantages of Injection Molding NdFeB Magnet

• Injection molded magnets offer lower magnetic performance than the compression bonded magnets (due to lower magnetic loading)
• Possible tooling charges for production and magnetising

Typical Applications of Injection Molded (Plastic) Magnets

• Motors
• Sensors
• Injection molded rotor assemblies
• Insert molded magnetic components
• Overmolded magnetic components

This means that you can produce magnets if you have injection molding machine and molding tooling. Also, you can produce strong and complex magnetic force by magnetic field molding. we have wide range of grade with wide variety of magnetic performance suitable for your application. Please feel free to consult us. We will support you how to use materials.
