From raw materials to finished fuse carriers, ZHNYU ELECTRIC controls every step of the manufacturing process to guarantee world-class quality. Established in 1992, our factory occupies 10,000 square meters and houses 100+ state-of-the-art production and testing machines. We produce over 3 million fuse carriers each year, with an in-house tooling department that enables rapid customisation at minimal cost. Our production flow begins with precision die-casting and injection molding of materials like PA66 and glass-fiber reinforced plastics, followed by automated stamping of silver-alloy contacts to ensure superior conductivity and lower temperature rise. Automated assembly lines employ sensor-guided robotics to maintain accuracy and repeatability, while 100% electrical testing using our proprietary test rigs validates every unit's contact resistance and dielectric strength.
