These critical components include copper terminals for high-current electrical connections, moving contact plates for switching mechanisms, air tubes for pneumatic systems, and DT4C armatures for electromagnetic actuators. Each component must meet stringent requirements for electrical conductivity, thermal stability, and mechanical strength. Our manufacturing expertise covers pure copper (C110) for terminals requiring maximum electrical conductivity, precision-machined moving contact plates with silver or tin plating for reliable switching performance, corrosion-resistant air tubes for pneumatic actuation systems, and DT4C electrical steel for armatures with excellent magnetic properties. Advanced CNC machining centers produce components with tolerances as tight as ±0.005mm, ensuring perfect fit and reliable performance in high voltage DC systems. Each part undergoes rigorous quality inspection including dimensional verification, conductivity testing, and material analysis. Surface finishing options include silver plating (5-10 μm) for superior conductivity and oxidation resistance, tin plating for corrosion protection, and specialized coatings for enhanced durability in harsh automotive environments. We support both rapid prototyping for new model development and volume production for OEM requirements. With comprehensive material traceability and IATF 16949:2016 certification, our components meet the automotive industry's highest quality standards for electric vehicle high voltage systems. ## Technical Specifications | Material | C110 Copper (99.9% purity), DT4C Electrical Steel | Process | CNC Milling, CNC Turning, 5-Axis Machining | Tolerance | ±0.005mm standard, tighter on request | Surface Finish | Silver Plating (5-10 μm), Tin Plating (3-5 μm) | Electrical Conductivity | ≥58 MS/m for copper components | Magnetic Properties | High permeability for DT4C armatures | Lead Time | 3-5 days for prototypes, 2-3 weeks for production | Compliance | IATF 16949:2016, ISO 9001:2015, ISO 14001:2015 ## Applications ### High Voltage DC Systems Copper terminals and busbars for high-current electrical connections in battery and motor systems ### Switching Mechanisms Precision moving contact plates for relays, contactors, and high-voltage switching systems ### Pneumatic Systems Corrosion-resistant air tubes for pneumatic actuation and braking systems ### Electromagnetic Actuators DT4C armatures for solenoids, relays, and electromagnetic switching components ### Charging Systems High-current terminals and connectors for fast charging and DC charging stations ### Electric Vehicles Complete electrical connection solutions for EVs, HEVs, and PHEVs ## Manufacturing Capabilities 50+ CNC Machines ±0.005mm Precision Tolerance 3-5 Days Delivery IATF 16949 Certified ## Frequently Asked Questions ### Do you comply with IATF 16949 for automotive parts?
