Direct answer: Zhengna Technology manufactures automotive hood hinge components from buyer drawings, with focus on stamping accuracy, forming, pivot fit, plating, corrosion resistance, and repeatable assembly performance.
| Buyer check | Why it matters |
|---|---|
| Material and thickness | Controls strength, spring behavior, corrosion resistance, and tooling route. |
| Critical dimensions | Defines fit, mounting, retention force, and assembly repeatability. |
| Burr and edge condition | Prevents trim, wire, hose, or operator damage. |
| Surface treatment | Supports corrosion resistance, appearance, conductivity, or sliding behavior. |
| Packaging | Prevents scratches, deformation, and mixed-lot shipment. |
Hole position, pivot fit, strength, coating quality, and assembly repeatability are usually most important.
Yes. Zhengna Technology can coordinate surface treatment and inspection according to buyer requirements.
Send drawings, material, finish, tolerance, pivot or hole requirements, annual volume, and inspection needs.
