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.
