Anisotropic Injection Molded Magnet Item No. AIBM-03
Format: The mechanical and magnetic values vary depending on the material used. The magnet is BLACK epoxy coated.
The materials used in injected magnets are mainly polyamides. (PA6 – PA11 – PA12).
These types of injected magnets are more resistant to corrosion than the sintered materials, therefore, they can be used for most applications without special coatings.
Maximum working temperature: Dependent on the material used.
For PA12, maximum working temperatures of 100ºC are possible, and approximately 120ºC for PA6. Polyphenol is used for working temperatures up to 200ºC, because its results with high temperatures are very positive. Epoxy resins may be used at temperatures of up to 120ºC.
Remarks: One of the main advantages of plastic magnets is the variety of moulding options offered by the injection process.
Areas of use: Motors, magnetic encoders for domestic appliances, washing machines, the automotive industry, etc.
Measures: According to customer specifications.
In injection molding process the magnet material can be directly molded into, or against other assembly components avoiding subsequent assembly steps. The magnets can be of different shapes and sizes. The importance of the injection moulding magnet lies in its cost effectiveness. Moreover, all or some part of the device can be magnetized. injection bonded anisotropic ndfeb magnet
The materials normally used for making injection molded magnets areferrite, neodymium-iron-boron (NdFeB), and samarium cobalt (SmCo). Magnetic powders include ferrite, neodymium-iron-boron (NdFeB), and samarium cobalt (SmCo). Different alloys of ferrite and NdFeB provides many different magnetic properties. Polymer binders improve physical strength, improve corrosion resistance for the rare earth magnetic materials, improve dimensional stability in the presence of water and solvents and ease processing.
