Injection Bonded Anisotropic NdFeB Magnet Item No. AIBM-02
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.
Injection Bonded Anisotropic NdFeB Magnet
The common molding technics of anisotropic ndfeb magnet are injection molding and compression molding. Two major application samples of anisotropic ndfeb magnet are sensor magnet and expansion valve.
Injection bonded ndfeb sensor magnets made by HDDR ndfeb powder are widely used for auto speedometer, speed sensor, water temperature sensor etc. The surface magnetic field can reach 3000GS upwards, needle axis remained in the body of ndfeb magnet when injection molded, which is in favor of forming the excellent maving balance. anisotropic injected bonded magnets
Electric expansion valve adopts HDDR injection magnetic ring that made by anisotropic ndfeb powder features good properties 30%~60% higher than other expansion valves made by common anisotropic ndfeb ring, thus, it can highly advance energy-efficiency-rate of air conditioner, and promotes the development of frequency conversion air conditioner towards energy-saving and environment-protection.
