Copper Stamped Parts Components
Products Description
The high-purity electrolytic copper substrate possesses inherent electrical and thermal conductivity properties that meet the continuous current-carrying requirements of high-power electrical equipment, avoiding the overheating and oxidation failure risks associated with low-purity copper. The closed-loop precision stamping process ensures stable and controllable dimensional tolerances. Copper Stamped Parts Components can be adjusted for bending, openings, and flexible cantilever structures according to customer 3D drawings, eliminating the need for additional mold design redundancy. A complete extreme environment reliability verification system, including high and low temperature, damp heat cycling, salt spray, and high-current continuity testing, covers the harsh operating conditions of new energy vehicles and energy storage power distribution systems.
Product Advantages
Material Advantages
All components use homogeneous pure copper sheets as raw materials, abandoning copper alloys and copper-clad steel composite substrates. Copper Sheet Metal Parts have uniform grain size and unobstructed conductive paths. The inherent low resistivity of pure copper reduces Joule heat loss during equipment operation, and its current-carrying capacity is more than 30% higher than that of brass and bronze stamped parts of the same cross-sectional area. Long-term full-load operation ensures stable temperature rise, reducing fuse and contactor overheating and contact erosion failures.
Process Advantages
Utilizing a multi-station continuous cold stamping forming process, blanking, bending, punching, and pre-pressing elastic deformation processes are completed in a single feed. The surface of the Copper Pressed Parts is free of cutting burrs and stress concentration areas. Following stamping, a leveling and stress-relief annealing process is performed to eliminate internal stresses caused by stamping deformation, preventing structural deformation and contact resistance drift under long-term thermal cycling, and ensuring that the dimensional accuracy of switches and relays remains unchanged after millions of switching cycles.
Reliability Advantages
Before product finalization, complete accelerated aging tests are conducted, simulating outdoor humid and hot conditions in energy storage power stations, high and low temperature shocks in vehicle electrical control systems, and frequent start-stop operations with high current in charging piles. The fatigue life of the elastic conductive structure of the Copper Stamped Components for Electrical Equipment has been verified through millions of switching cycles, and the contact resistance fluctuation range is controlled within the engineering allowable threshold, eliminating the risk of long-term intermittent connections and arcing.
Detailed Characteristics
Custom Stamped Parts In Copper: Flatness and edge quality are carefully controlled in conductive connection areas to reduce local contact anomalies.
For complex structural components, Custom Copper Stamping Components can be developed, using multi-station continuous dies to reduce secondary processing, improve batch consistency, and increase production efficiency.
The localized bending areas of the Copper Plate Sheet Metal Parts have been validated to reduce the risk of stress concentration during forming and improve long-term mechanical stability.
