Stamped Armature Plate For High-Voltage EV Relay
Products Description
In the high-voltage DC relay system of new energy vehicles, the armature serves as both the primary force-transmitting element and the central magnetic flux carrier within the electromagnetic actuation module. Its characteristics directly govern the relay's pick-up response time, sealing stability, and operational endurance over the product lifecycle. This component is a custom-engineered stamped armature specifically developed for automotive-grade high-voltage relays, targeting main-circuit and power-control applications in new-energy vehicle architectures. Every aspect-from raw material selection through to manufacturing-is optimized to satisfy the rigorous demands of onboard high-voltage environments, ensuring dependable performance under high-frequency switching, sustained duty cycling, and extreme thermal excursions. The product presented here is our standardized core offering developed precisely for this application segment.

Technical Features
Low Remanent Magnetism Design
Based on the material properties of high-purity pure iron, and combined with a stress-relief annealing process, the Movable Armature Plate for EV Relay controls residual magnetism to an extremely low level, preventing sticking failure after power failure.
Low Internal Stress Forming
By eliminating stamping internal stress through an annealing process, the Precision Stamped EV Relay Armature will not deform after long-term cyclic use, ensuring stable engagement gaps.
High-Precision Installation and Positioning
The tolerances of the mounting holes and positioning surfaces of the Armature in Relay are strictly controlled, adapting to automated assembly and eliminating the need for manual adjustments, reducing assembly costs for customers.
Comparison with Competitors
Raw Material Control Comparison
Competitors mostly purchase semi-finished iron materials for processing, while our factory directly purchases original electrical pure iron coils. Carbon content and magnetic performance indicators are more strictly controlled, resulting in a significantly lower magnetic performance dispersion for the Pure Iron Armature for EV Relay compared to competitors.
01
Manufacturing Consistency Comparison
Most manufacturers use single-die small-batch stamping, while our factory uses fully automated continuous die mass production + Online inspection results in smaller fluctuations in the dimensions and magnetic properties of workpieces within the same batch, reducing the defect rate of mass assembly by over 40%.
02
Comparison of process integrity
Some manufacturers only perform the stamping process, outsourcing surface passivation. Our factory independently completes the stamping, passivation, and inspection of Armature Metal Parts of Relays, ensuring consistent and controllable film thickness and corrosion resistance parameters.
03
Comparison of supply chain support
While competitors only produce Armatures for Electromagnetic Relays, our factory can simultaneously deliver all metal components for relays, providing one-stop support and reducing the cost of managing multiple suppliers for our customers.
