Direct answer: Zhengna Technology manufactures E-coated automotive lift mechanism springs for seats, consoles, lids, and interior mechanisms where load stability, coating quality, fatigue risk, and paired spring consistency matter.
| Buyer check | Why it matters |
|---|---|
| Material and wire diameter | Controls load, fatigue life, corrosion resistance, and forming stability. |
| Load points and working range | Confirms the spring performs in the real installed condition. |
| Heat treatment or stress relief | Stabilizes force, dimensions, and fatigue behavior after forming. |
| Surface treatment | Matches corrosion, appearance, and assembly environment requirements. |
| Inspection and packaging | Protects traceability, load consistency, and deformation-free shipment. |
They can be used in seats, consoles, lids, storage modules, and other interior lift or return mechanisms.
E-coating can support corrosion protection and appearance when coating coverage and spring performance are verified.
Buyers should inspect load points, dimensions, coating appearance, fatigue expectation, and packaging condition.
