Products Description
Switch Copper Stamping Parts are core metal components of switches manufactured using high-conductivity copper strip as a base and through high-speed precision stamping processes. They are widely used in conductive or structural parts within various mechanical switches, relays, selector switches, and modular electrical devices. These parts perform critical functions such as current transmission, elastic recovery, and mechanical positioning, and their geometric consistency and surface quality directly determine the electrical stability and assembly reliability of the entire device.
Material Advantages
Superior Electrical Conductivity
Copper boasts an electrical conductivity ≥98% IACS, ranking among the highest of all metals. During switch operation, current flows efficiently and smoothly through the stamped parts, reducing energy loss and improving electrical system efficiency. In large industrial power distribution systems, Copper Strip Stamping can result in significant energy cost savings.
Excellent Thermal Conductivity
Frequent switch operation generates substantial heat. Copper Stamping Contact For Electrical Switch rapidly conduct heat, preventing localized overheating that could lead to performance degradation or damage. This ensures stable switch operation and extends service life.
High Strength and Good Ductility
With a tensile strength of 200-300 MPa (soft state), the stamped parts can withstand certain mechanical stress after stamping, making them resistant to deformation and damage. Copper Stamping Parts excellent ductility allows for easy stamping of complex shapes, meeting diverse switch design requirements, and perfectly adapting to special-shaped switches.
Quality Control and Process Verification
Incoming Material Inspection
A spectrometer is used to confirm that the material composition conforms to the C1100/T2Y2 copper standard. Thickness and hardness are tested, and tensile tests are performed to verify mechanical properties for Switch Socket Precision Custom Metal Stamping Parts.
Stamping Process Control
Based on material specifications, the stamping press for Copper Stamping Contact For Electrical Switch tonnage is set to 5–200 tons, and the stamping speed to 200–800 times/minute. An online vision system continuously monitors burrs, missing material, and forming defects, enabling immediate rejection.
Finished Product Inspection
Key dimensions for Copper Stamping Parts are measured using automatic inspection equipment and a projector, with tolerances controlled within ±0.02 mm. Conductivity (≤0.5 mΩ), insertion force, and pull-out force are simultaneously verified to meet customer assembly and usage requirements.
Material and Performance Customization
• Substrate and Surface Treatment Customization: We can select C1100/T2Y2, C1020, and other copper substrates based on customer current requirements, operating environment, and cost budget, adjusting parameters such as hardness and tensile strength. Surface treatments include tin plating, silver plating, and passivation. For special environments, parameters can be optimized to improve corrosion resistance and prevent oxidation and peeling for Copper Strip Stamping.
• Mechanical and Electrical Performance Customization: We optimize processes to reduce on-resistance for high-voltage switches, strengthen mechanical support for large switches, and customize low-loss solutions for new energy switches, all meeting stringent requirements and RoHS and REACH environmental standards for Copper Stamping Parts.
