Automotive Sun Visor Wire Frame: The Backbone of Smooth Operation
This product image from Zhejiang Zhengna Technology Co., Ltd. features a precision-formed sun visor wire frame, the essential internal skeleton that provides structure and defines the pivot points for a vehicle's sun visor. The silver-white, high-carbon steel wire is expertly bent into a specific, complex 2D shape with consistent radii and angles, showcasing our capability in high-volume precision wire forming. This component is critical for ensuring the visor's smooth rotation, stable positioning, and overall tactile quality.

Product Specifications & Technical Details
| Feature |
Specifications |
Functional Importance |
| Base Material |
-
High-Carbon Steel Wire (e.g., SAE 1075) or Spring Steel Wire.
- Selected for optimal balance of strength, formability, and elastic memory.
|
Provides the necessary rigidity to hold the visor shape while allowing for slight flex during use without permanent deformation. |
| Wire Forming Process |
-
Precision CNC Wire Bending on multi-axis machines.
- Capable of creating complex 2D shapes with tight bend radii and accurate angles.
- Secondary operations: cutting, coining (for flat sections), or welding if needed.
|
Ensures every wire frame is identical, which is crucial for consistent fit, feel, and function in high-volume automotive assembly. |
| Critical Dimensions |
-
Wire Diameter: Customized (typically 3mm to 5mm range).
-
Bend Angles & Radii: Held to tight tolerances (±0.5° and ±0.1mm typical).
-
Overall Contour: Precisely matches the CAD design of the visor assembly.
|
Directly affects the visor's fit within the headliner, its range of motion, and the alignment of mounting points for hinges and clips. |
| Surface Finish |
-
Bright Electro-Galvanized (as shown) for a clean, corrosion-resistant finish.
- Alternative: Zinc-Nickel plating for enhanced corrosion protection, or powder coating for specific colors.
|
Prevents rust during the vehicle's lifespan, maintains a clean appearance (if visible), and can provide a slight lubricity for smooth rotation in pivot points. |
| Primary Application |
Serves as the internal reinforcing structure and pivot framework for driver and passenger side sun visors in passenger vehicles, SUVs, and trucks. |
A single, critical component that determines the functional integrity and perceived quality of the sun visor module. |
Why Choose Our Sun Visor Wire Frames?
-
Precision for Perfect Fit and Feel: We understand that the wire frame dictates the visor's movement. Our CNC wire bending guarantees dimensional accuracy, ensuring every visor has the same smooth, rattle-free operation with consistent damping.
-
Designed for Automated Assembly: The frames are formed with precise locating features (bends, ends) that facilitate easy and correct insertion into visor boards and attachment of hinges/clips in high-speed assembly lines.
-
Material & Process Consistency: We control the wire sourcing, bending, and finishing processes to deliver batch-to-batch consistency in strength, geometry, and surface quality, which is paramount for automotive Tier-1 suppliers.
-
Full-Service Engineering Support: We can work from your visor design to develop the optimal wire frame geometry, or refine an existing design for better manufacturability and performance.
-
IATF 16949 Quality Assurance: Our production follows strict automotive quality protocols, including first-article inspection, statistical process control (SPC), and salt spray testing on plated samples to ensure long-term durability.
Our Manufacturing & Quality Process
-
Design Analysis & Prototyping: Review of 2D drawings/3D models. Production of sample wires for fit-check and functional testing in your visor assembly.
