[Hunan · Changsha] In the field of heavy machinery manufacturing, welding and transporting steel structures weighing several tons have long relied on slings and manual positioning—processes that are not only inefficient but also pose significant safety risks. Now, Qianhao Magnetic Electric’s newly developed "Panshi Series" electro-permanent magnetic welding fixtures are revolutionizing production line operations with their groundbreaking magnetic technology. By equipping robotic arm end-effectors with these "smart magnets," the three critical steps—workpiece adsorption, sorting & positioning, and welding clamping—are now seamlessly integrated into a fully automated, unmanned workflow for the first time.

On the land of Yueyang, Hunan—a region that has long been a symbol of China's industrial glory—a revolution in magnetic technology is reshaping the global landscape of industrial equipment. Once hailed as China's "Magnetic Capital," Yueyang's electromagnet industry has weathered half a century of ups and downs. Now, thanks to the pioneering efforts of companies like Qianhao Magnetic Electric, the industry has successfully made a technological leap—from traditional electromagnets to electro-permanent magnets—breaking foreign monopolies and achieving full domestic substitution.

While striving for mold-change efficiency, the risk of molds slipping or falling has always remained a critical safety red line in manufacturing. Traditional magnetic fixtures, plagued by issues such as residual magnetism and uneven magnetic fields, have led to persistently high rates of mold displacement incidents. Qianhao Magnetic & Electric, through systematic technological innovation, has elevated safety standards to an "zero-error" level. Their core solution has already earned EU CE certification.

In the wave of transformation and upgrading in manufacturing, mold-changing efficiency has become a critical bottleneck restricting production line flexibility. Traditional mechanical clamping methods rely on bolt-by-bolt tightening, requiring 2 hours to change molds on a single 380T injection molding machine—and even longer, up to 4 hours, for a 3,000-ton die-casting machine. These processes demand the labor of 3 to 4 workers, resulting in significant equipment downtime and substantial operational losses. However, Qianhao Magnetic Electric, leveraging its independently developed electro-controlled permanent magnet technology, has completely redefined the paradigm of mold-changing processes.
