New energy vehicle high voltage DC structural components are precision-engineered parts designed for electric vehicle electrical connection systems. 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.
