Products Description
Contactor Copper Stamping Parts are electroplated copper stamping parts specifically designed for the internal conductive structures of switchgear, circuit breakers, and power contactors. These parts use highly conductive copper as a base material, are precision progressively stamped, and then electroplated for surface treatment. They are used to achieve key functions such as main circuit current transmission, contact support, and arc guidance. The products balance high current carrying capacity, low temperature rise, and structural stability, making them suitable for new energy storage systems, industrial power distribution devices, and rail transit switchgear. They are core conductive components in medium- and high-power switching systems.
Production Process
Substrate Pretreatment
The Copper Part Stamping substrate undergoes pretreatment processes such as cleaning, polishing, and annealing to remove surface oil, oxide layers, and impurities, eliminate internal stress, and improve the stamping formability and surface smoothness. Simultaneously, the substrate is processed into precision strips, ensuring thickness tolerance is controlled within ±0.01mm, laying the foundation for subsequent stamping and electroplating processes.
Precision Stamping
Utilizing customized molds and automated precision stamping equipment, multiple processes including blanking, punching, bending, and forming are integrated. The blanking gap is adjusted according to the copper strip thickness, achieving a production efficiency of up to 500 times per minute. Real-time monitoring of mold alignment accuracy and stamping dimensions during the stamping process ensures precise dimensions, burr-free, and deformation-free High Precision Progressive Stamping Copper Parts.
Electroplating
Precision electroplating equipment Copper Stamping Electrical Precision Parts is used, selecting tin or silver plating processes according to customer requirements. Strict control of the electroplating layer thickness is maintained, and electroplating parameters are monitored in real-time to ensure a uniform and dense plating layer. Passivation treatment is performed after electroplating to improve the corrosion resistance of the plating layer and prevent oxidation and discoloration.
DFM and Value Engineering
Manufacturability Analysis
Intervening in the design phase to optimize Precision Copper Stamped Parts geometry, tolerances, and material selection to improve manufacturability, reduce costs, and shorten cycle times.
Performance Simulation and Optimization
Assisting with simple simulations and analyses of electromagnetic, thermal, or structural forces to optimize Copper Stamping Electrical Precision Parts design.
Cost-Effective Solutions
Assisting clients in achieving cost targets for High Precision Progressive Stamping Copper Parts through material substitution, process integration (such as progressive dies), and localized plating.
Packaging and Delivery Time
For packaging, we employ a multi-layered protective structure from the inside out: the inner layer uses thick plastic bags for moisture protection, the outer layer is a reinforced cardboard box, secured with strapping, and the entire box is then wrapped in stretch film for added protection. Finally, we use pallets and secure them with strapping to ensure the safety and stability of the Copper Part Stamping during transportation and handling.
Regarding delivery time, free samples are typically shipped within 1–2 days; sample projects involving new molds have a lead time of approximately 20–30 days; bulk orders for High Precision Progressive Stamping Copper Parts, after confirmation and payment, generally have a delivery time of 15–20 days, meeting the delivery needs of different project stages.
