In the safety protection system of power distribution systems, molded case circuit breakers (MCCBs) serve as core protection devices, and the reliability of the connections of their internal components directly determines the operational stability and service life of the equipment. Aluminum blind rivets, as critical internal fasteners of MCCBs, bear multiple responsibilities, including component fixation, circuit insulation, and structural reinforcement.
Having cultivated expertise in the field of customized fasteners for many years, we specialize in developing and manufacturing customized aluminum blind rivets for MCCBs, offering enhanced adaptability and more stable performance. These rivets precisely match the structural requirements of different MCCB models, building a solid first line of defense for the safety of power equipment.
Made of high-purity 6061, 5052 and other special aluminum alloy materials. While reducing the overall weight of the circuit breaker, it can stably withstand the stress caused by component vibration and thermal effects.
Through anodizing and passivation, a dense protective layer is formed which improves electrical insulation and resists humid environments, extending service life by more than 1.5 times.
Utilizing an optimized core-pulling structure for rapid single-sided riveting. The rivet head flatness error is controlled within 0.01mm, meeting precision assembly requirements.
Different models and application scenarios of MCCBs have different requirements. We establish a full-chain customization system covering "size – material – process – performance".
Diameters of 2.4mm–6.4mm and lengths of 5mm–35mm. Supports convex head and countersunk head options, accurate to 0.1mm.
Special high-temperature and corrosion-resistant alloys available. Weather-resistant rivets can withstand temperature fluctuations from -40℃ to 120℃.
Zinc plating, nickel plating, and black anodizing. Our insulating anodizing can achieve resistance over 10¹²Ω for high-voltage applications.
Supports vibration resistance, anti-loosening designs, and color marking (gold, silver, etc.) to facilitate assembly differentiation.
