Direct answer: Zhengna Technology manufactures custom metal clips and clamps from buyer drawings, including stamped fasteners, spring clips, retainers, and clamp hardware that require fit, force, burr control, coating, and packaging discipline.

| 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. |
Zhengna Technology can make stamped clips, spring clips, hose clamps, retainers, brackets, and custom clamp hardware from drawings.
Include drawing, material, thickness, finish, retention or clamping force, critical dimensions, quantity, and packaging.
Sharp edges or burrs can damage hoses, trim, wiring, operators, or coating, so burr limits should be defined early.
