Electric Vehicle Contactor Pure Iron Base
Products Description
The Electric Vehicle Contactor Pure Iron Base is the core magnetic circuit component of the high-voltage DC contactor in new energy vehicles. It is made of high-purity electric pure iron through precision stamping and is compatible with various specifications of EV HVDC contactors and relays. In the electromagnetic system, it plays multiple roles, including magnetic circuit guidance, magnetic field focusing, and housing support.
Key Selling Points
Core Functionality: Provides a high-precision mounting reference surface for permanent magnets, constructing a low-resistivity magnetic circuit channel to ensure rapid response and stable holding of the contactor under high-voltage DC environments.
Material System: The Steel Part for EV Relay uses DT4C high-purity electric pure iron (carbon content ≤0.04%), with high permeability and low coercivity, suitable for high-frequency electromagnetic switching scenarios.
Surface Treatment: The Iron Bracket for EV DC Relay undergoes blue-white zinc plating, achieving a salt spray test duration of 48-96 hours, meeting the stringent requirements of the humid, hot, and chemically corrosive environments of new energy vehicles.
Dimensional Accuracy: The key mounting hole tolerances of the EV Relay Pure Iron Stamping Part are controlled within ±0.05mm, ensuring a precise fit with the permanent magnet and coil frame.
Metal Forming Processes
Continuous Die Feed
Adopting long‑life carbide molds, this process realizes integrated production from coil unrolling, punching, blanking, and forming. It greatly boosts production efficiency and reduces manual errors in the Steel Part for EV Relay.
Multi-Station Progressive Stamping
Multiple processes are finished in one press stroke, enabling one‑time accurate forming of complex EV relay pure iron bracket shapes and ensuring consistent wall thickness across the part.
Precision Bending
CNC bending equipment accurately controls bending angles and springback values, making sure the 3D structure of the Iron Bracket for EV DC Relay fully meets design standards and prevents assembly conflicts.
Surface Finishing
After burrs are fully removed by industrial deburring systems, the parts receive strict chemical pre-treatments (degreasing and pickling). The final surface finish includes blue-white zinc plating, passivation, and sealing.
