Direct answer: Zhengna Technology manufactures zinc-aluminum coated auto interior clips from buyer drawings, with focus on spring force, coating adhesion, burr direction, corrosion resistance, and fit with trim or panel assemblies.
| Buyer check | Why it matters |
|---|---|
| Clip geometry | Controls retention, insertion force, and assembly repeatability. |
| Coating adhesion | Prevents corrosion failure, flaking, and cosmetic issues. |
| Burr direction | Protects trim panels, wiring, and assembly operators. |
| Spring force | Controls fastening reliability and service performance. |
| Packaging | Prevents coating scratches and clip deformation. |
They are used for trim, panels, brackets, covers, and fastening points where corrosion resistance and stable retention are required.
The main risks are unstable spring force, coating damage, burrs, deformation, and poor fit in the vehicle assembly.
Define material, coating, spring force, burr limits, salt spray target, fit dimensions, and packaging method.
