Direct answer: Zhengna Technology manufactures CNC machined and bent pipe tubes for automotive sun visor and sun shield assemblies from buyer drawings. Buyers should control bend angle, end geometry, surface finish, fit with plastic parts, and batch inspection before production approval.
| Buyer check | Why it matters |
|---|---|
| Bend angle and radius | Controls visor fit, rotation, and assembly repeatability. |
| End geometry | Affects insertion, fastening, welding, or plastic overmold fit. |
| Material and finish | Controls strength, corrosion resistance, appearance, and handling risk. |
| Critical dimensions | Guides inspection for tube length, hole position, and mating features. |
| Packaging | Prevents tube scratches, deformation, and mixed-lot shipment. |
Include drawings, material, wall thickness, bend radius, end geometry, finish, critical dimensions, annual volume, and inspection requirements.
Bend angle control affects assembly fit, motion, plastic trim alignment, and repeatability in automotive sun visor hardware.
Yes. Zhengna Technology can check critical tube length, bend angle, hole position, end features, surface quality, and packaging condition.
