Raw Material Control
Strict sampling of steel yield strength is carried out to ensure that it is within a reasonable error range, and the inspection standard strictly follows the relevant metal tensile test standards.
Forming Process Control
Advanced online monitoring technology is used to monitor the forming process in real time to ensure that the bending rebound is effectively compensated and follow the industry standards for automotive stamping parts.
Surface Treatment Inspection
The surface coating is carefully inspected and the coating thickness error is strictly controlled. The product must pass a professional salt spray test to ensure the surface treatment quality.
Assembly Verification
Multiple plug-in and pull-out life tests are carried out on bolted connectors, strictly in accordance with the specification requirements of threaded fasteners to ensure assembly quality and reliability.
