Customized Aluminum Blind Rivets for Molded Case Circuit Breakers - China Suppliers & Factory
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, and avoid safety hazards caused by loose connections.
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 the humid environment and corrosive gases inside the circuit breaker, extending the service life by more than 1.5 times that of standard parts.
Utilizing an optimized core-pulling structure design, it achieves rapid single-sided riveting, enabling a secure connection without requiring complex operating space. During the riveting process, the rivet sleeve expands precisely, forming a tight-fitting "safety lock" structure with the component. After locking, the rivet head flatness error is controlled within 0.01mm, fully meeting the precision assembly requirements of circuit breakers.
We can precisely customize rivet products according to the riveting hole diameter and interlayer thickness of circuit breaker components. The rivet head style supports multiple options such as convex head and countersunk head, and the clamping range can be accurate to 0.1mm, perfectly adapting to special space installation requirements.
For special working conditions such as high temperature and high humidity, special materials such as high temperature resistant aluminum alloy and corrosion resistant alloy can be customized. By adjusting the alloy composition ratio, the strength, toughness and thermal conductivity can be precisely matched for outdoor and demanding environments.
We offer a variety of surface treatment options, including 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 special needs such as vibration resistance, anti-loosening, and color marking. Anti-vibration rivets for rail transit circuit breakers improve connection stability under vibration; gold, silver and other marking colors can be customized to facilitate specification differentiation during production.
