Recently, Ningbo Buer Magnetic & Electric Technology Co., Ltd. has continued to advance the application of its magnetic components in automotive electronic actuators. Founded in 2018, the company has long specialized in the research, development, and manufacturing of bonded magnets—commonly known as “plastic magnets” or “injection-molded magnets”—as well as injection-molded magnet rotors. It is committed to delivering reliable magnetic solutions to customers across Zhejiang, Jiangsu, and surrounding regions.

Injection-molded magnets are functional composite materials formed by blending magnetic powders with engineering plastics through an injection molding process. They offer design flexibility, high dimensional accuracy, and excellent corrosion resistance—making them well-suited for applications where compact spatial layout and operational stability are critical. In automotive components such as air flap actuators and cooling system pumps, these magnets enable integrated molding of complex geometries with multi-pole magnetization, effectively meeting the modern automotive industry’s demands for miniaturization and reliability in electronic control systems.

Leveraging years of technical expertise from its core team in magnetic materials, Buer has developed PPS-based and PA-based injection-molded magnet products tailored to different operating conditions, built around both neodymium-iron-boron (NdFeB) and ferrite magnetic powder systems. The company’s plastic magnet rotors have already achieved volume supply in select automotive actuator programs and comply with relevant quality management system requirements, ensuring full traceability and control from raw materials to finished goods.

Throughout production, Buer emphasizes process stability and environmental responsibility, utilizing mature injection molding equipment and compliant engineering plastic resins to balance performance with sustainable manufacturing principles. Beyond the automotive sector, its injection-molded magnets are also being increasingly adopted in industrial applications such as elevator sensors and small water pump motors, demonstrating strong adaptability and market potential.

Looking ahead, Buer will continue to strengthen its localized service capabilities in Eastern China, reinforcing its identity as a professional “plastic magnet manufacturer.” The company plans to deepen collaboration with downstream customers and provide comprehensive technical support—from material selection to structural design recommendations—to promote the rational and effective use of injection-molded magnets in a wider range of end products.
