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, which combine the lightweight characteristics of aluminum materials with excellent shear strength. While reducing the overall weight of the circuit breaker, it can stably withstand the stress caused by component vibration and current thermal effect.
Through professional surface treatment processes such as anodizing and passivation, a dense protective layer is formed on the rivet surface, which not only effectively improves electrical insulation performance and prevents leakage risks, but also resists the erosion of humid environments.
Utilizing an optimized core-pulling structure design, it achieves rapid single-sided riveting. During the riveting process, the rivet sleeve expands precisely, forming a tight-fitting "safety lock" structure. The rivet head flatness error is controlled within 0.01mm.
Different models and application scenarios of molded case circuit breakers have different requirements for fastener specifications. Therefore, a full-chain customization system covering "size–material–process–performance" has been established to support a one-stop solution from drawings to finished products.
We can precisely customize rivet products with diameters of 2.4mm–6.4mm and lengths of 5mm–35mm according to the riveting hole diameter and interlayer thickness. The rivet head style supports multiple options such as convex head and countersunk head.
For special working conditions, special materials such as high temperature resistant aluminum alloy and corrosion resistant alloy can be customized. Weather-resistant aluminum rivets can withstand temperature fluctuations from -40℃ to 120℃.
We offer a variety of surface treatment options, including zinc plating, nickel plating, and black anodizing. The insulating anodizing process can achieve an insulation resistance of over 10¹²Ω on the rivet surface.
Supports customization for vibration resistance, anti-loosening, and color marking. For example, anti-vibration rivets for rail transit improve connection stability under vibration by adding a rivet sleeve texture design.
