Quality Control and Inspection Standards
Overall Quality Control System
The quality inspection system is built for the EV Relay Pure Iron Stamping Part in strict accordance with automotive industry standards. The whole-process quality is rigorously controlled to achieve zero-defect delivery of finished products.
01
Dimensional Precision Inspection
High-precision CMM measuring equipment is adopted to inspect the overall dimension of the Pure Iron Stamping Bracket for EV HVDC Contactor Assembly for each batch, so as to steadily control micron-level machining tolerances.
02
Anti-corrosion Coating Inspection
The quality of blue-white zinc coating is monitored in real time via coating thickness gauges, combined with a 96-hour neutral salt spray test. This enables the Stamped Pure Iron Bracket for Contactor to withstand the harsh and complex environment inside automobile engine compartments for long-term service with reliable anti-corrosion performance.
03
Magnetic Performance Sampling Test
Magnetic permeability and residual magnetism tests are conducted on batch samples to ensure smooth pull-in and breaking actions of relays for High Precision Pure Iron Stamping for EV Parts, and to avoid mechanical jamming during high-frequency switching operation.
Material Traceability Management
Certified mill test reports (MTR) are attached to every shipment to implement full-process traceability management for Electric Vehicle Contactor Pure Iron Base, covering the whole flow from raw material warehousing to finished product delivery.
