Anisotropic Injection Molded Permanent Magnets, Anisotropic Injection Molding Binders Bonded Neodymium Magnets, Bonded NdFeB Anisotropic Injected Magnet for washing machines, Neodymium-iron-boron unipolar & multipolar plastic ring magnets for domestic appliances
Anisotropic Injection Molded Permanent Magnets Item No. AIBM-05
Format: The mechanical and magnetic values vary depending on the material used. The magnet is gray 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.
Properties of Anisotropic Injection Molded Permanent Magnets
They are strong magnets with excellent physical strength.
They are resistant to breakage. As they are not very brittle their handling is easier on production assembly lines.
Through molding desired shapes of magnets can be obtained eliminating finishing operations.
The material is easily machinable. anisotropic injection molded magnet
With regard to dimensional precision they are excellent.
The advanced surface treatment technology effectively protects them and make them impact resistant.
The bonded Neodymium Iron Boron materials are typically anisotropic. They can be made isotropic, and are manufactured using “binders,” such as epoxy resins or nylon to hold the powder in place, rather than “sintering” the alloy. Energy products of the bonded magnet range from 5 MGOe to 10 MGOe. Two basic processes are used:
Compression Molding Binders are epoxy resins, and energy products of 10 MGOe are achievable. Moderately complex shapes can be achieved.
Injection Molding Binders are generally nylon, but epoxy resins may also be used. Energy products are lower than compression molding; however, more complex shapes can be achieved without final processing, which makes it cost effective for low to medium performance applications which are cost sensitive. bonded neodymium anisotropic injection molding magnets
The bonded Neodymium Iron Boron magnet may be used without surface treatment; however, coating is recommended. Generally, spray coatings are used, such has phenolic or epoxy coating.
