Customized Aluminum Blind Rivets for Molded Case Circuit Breakers - Reliable Factory Suppliers in China
Product Overview
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.
Product Features
Made of high-purity 6061, 5052 and other special aluminum alloy materials, combining lightweight characteristics with excellent shear strength. Stably withstands stress from component vibration and current thermal effects, avoiding safety hazards caused by loose connections.
Through professional surface treatments such as anodizing and passivation, a dense protective layer is formed on the rivet surface, improving electrical insulation performance and resisting humid environments and corrosive gases — extending service life by more than 1.5× that of standard parts.
Utilizing an optimized core-pulling structure design for rapid single-sided riveting. The rivet sleeve expands precisely, forming a tight-fitting "safety lock" structure. After locking, the rivet head flatness error is controlled within 0.01mm, meeting precision assembly requirements.
Full-Dimensional Customization One-Stop Solution
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.
Precisely customizable rivet products with diameters of 2.4mm–6.4mm and lengths of 5mm–35mm. Rivet head styles support convex head and countersunk head options. Clamping range can be accurate to 0.1mm, perfectly adapting to special space installation requirements.
For high temperature and high humidity working conditions, special materials such as high-temperature resistant and corrosion-resistant alloys are available. Weather-resistant aluminum rivets for outdoor circuit breakers can withstand temperature fluctuations from -40℃ to 120℃.
Options include zinc plating, nickel plating, and black anodizing. The insulating anodizing process developed for precision circuit breakers achieves an insulation resistance of over 10¹²Ω on the rivet surface, meeting the requirements for high-voltage applications.
Supports customization for vibration resistance, anti-loosening, and color marking. Anti-vibration rivets for rail transit circuit breakers improve stability under vibration via rivet sleeve texture design. Gold, silver, and other marking colors can be customized for specification differentiation during production.
