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. Specializing in developing and manufacturing customized aluminum blind rivets for MCCBs, these products offer 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.
Different models and application scenarios of molded case circuit breakers have different requirements for fastener specifications. A full-chain customization system covering "size-material-process-performance" has been established to support solutions from drawings to finished products.
Rivet products with diameters of 2.4mm-6.4mm and lengths of 5mm-35mm can be precisely customized. The rivet head style supports multiple options such as convex head and countersunk head, with clamping range accurate to 0.1mm.
Special materials such as high temperature resistant aluminum alloy and corrosion resistant alloy can be customized for harsh working conditions. For example, weather-resistant aluminum rivets can withstand temperature fluctuations from -40°C to 120°C.
Options include zinc plating, nickel plating, and black anodizing. The insulating anodizing process can achieve an insulation resistance of over 10¹²Ω on the rivet surface, meeting high-voltage application requirements.
Supports needs such as vibration resistance, anti-loosening, and color marking. Anti-vibration rivets for rail transit improve connection stability under vibration through specific sleeve texture designs.
A: We primarily use high-purity 6061 and 5052 aluminum alloys to ensure an optimal balance between lightweight properties and high shear strength.
A: Yes, with our specialized insulating anodizing treatment, the rivet surface can achieve an insulation resistance exceeding 10¹²Ω.
A: We can customize diameters ranging from 2.4mm to 6.4mm and lengths from 5mm to 35mm to fit specific circuit breaker designs.
A: Our customized weather-resistant models are designed to operate reliably within a temperature range of -40°C to 120°C.
A: Yes, we provide anti-vibration rivets featuring a specific sleeve texture design that enhances locking stability under constant vibration.
A: The rivet head flatness error is strictly controlled within 0.01mm to meet the high-precision requirements of modern circuit breaker assembly.
