Injection Molded Magnets
As pioneers in the industry, we offer a comprehensive range of injection molded magnets, including injection molded NdFeB magnets, injection molded SmCo magnets, and injection molded ferrite magnets.
Injection Molded NdFeB Magnets
Injection molded NdFeB magnets offer a combination of steel-like strength and flexibility, allowing for thin-walled shapes such as rings, bars, and even more complex designs. By embedding magnets and other metal components (such as gears, screws, and irregular holes) in a single mold, cracking and breakage are significantly reduced. Plus, the precision and surface finish are top-notch, with high product yields and consistent magnetic fields. These magnets also exhibit excellent corrosion resistance.
Applications for injection molded NdFeB magnets are endless, including sensors, brushless motors, automotive electronic throttle pedals, instrument clusters, tachometers, fuel gauges, and more.
