Injection Molded Magnets

Prepare to witness a magnetic transformation like never before with NGYC's extraordinary lineup of 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.

At NGYC, we offer injection molded SmCo magnets, which are produced using advanced injection molding technology. This method enables one-step molding of complex shapes, reducing assembly processes and improving assembly precision. With strong corrosion resistance and high temperature stability, the magnets require no surface treatment.

Applications
  • Automotive Industry: From automotive sensors to motor components and instrument clusters, our magnets provide reliable and efficient performance, even in the harshest conditions.
  • Precision Machinery: Our injection molded SmCo magnets are ideal for use in laser printers, copiers, and fax machines. Additionally, they provide exceptional magnetic properties for electric motors, enhancing their efficiency and reliability.
