Details & Variations (As Pictured) |
Design & Functional Purpose |
| Base Material & Forming |
-
Material: High-Quality Steel Tube or Aluminum Tube for lightweight applications.
-
Process:Precision CNC Tube Bending to achieve consistent, complex 2D or 3D bend geometries with tight tolerances.
|
Creates the exact skeletal shape needed to fit the visor's foam/board core and align with mounting points in the vehicle's A-pillar or roof structure. |
| Surface Finishes |
-
Black & Light Gray:Powder Coating or E-Coating. Provides durable corrosion protection, a clean appearance, and can be color-matched to internal components.
-
Silver with Knurl:Bright Zinc or Nickel Plating with a knurled section for enhanced grip and mechanical adhesion when overmolded with plastic or bonded within the visor assembly.
|
Finish selection balances aesthetics, corrosion resistance, and functional needs like bonding strength. The knurl provides a secure locking interface with plastic housings. |
| Key Design Features |
-
Custom Bend Profiles: Each bend and straight section is calculated to match the visor's contour and pivot points.
-
End Forming: Ends can be flattened, drilled, tapped, or notched to facilitate screw attachment, clip mounting, or pivot pin installation.
-
Dimensional Consistency: Critical for ensuring every visor has the same fit, swing arc, and retraction tension.
|
The tube's geometry directly dictates the visor's range of motion, stability when stowed, and overall tactile quality. Precision is paramount. |
| Primary Application |
Serves as the internal reinforcing spine and pivot framework within the driver and passenger side sun visors of cars, trucks, and SUVs. |
A single, critical component that determines the functional integrity, feel, and longevity of the sun visor assembly. |
Why Choose Our Sun Visor Bent Tubes?
-
Expertise in Precision Tubing for Automotive Interiors: We specialize in transforming straight tubes into complex, dimensionally-critical forms that fit perfectly into confined interior spaces and interact with multiple other components.
-
Diverse Finishing Capabilities for Any Requirement: As shown, we offer a range of finishes—from decorative and protective coatings to functional plated finishes with mechanical features like knurls. We select the optimal process for your application's performance and cost needs.
-
Focus on Repeatability and Batch Consistency: For automotive production, every part must be identical. Our CNC bending and controlled finishing processes ensure exceptional batch-to-batch consistency in shape, dimensions, and surface quality.
-
Full-Service Engineering Support: We can work from your visor design to develop the optimal tube geometry and specification, or manufacture to your exact provided drawing, ensuring the part integrates seamlessly.
-
Commitment to Automotive Quality Standards: Our production follows stringent quality protocols suitable for supplying to Tier 1 and OEM manufacturers, with a focus on durability and performance validation.
Our Tube Bending and Fabrication Process
-
Design Analysis & Prototyping: Review of 2D drawings/3D models. Production of sample tubes for fit-check and functional testing within your visor assembly.
-
Precision Tooling & Programming: Setup of CNC tube benders with custom mandrels and wiper dies to achieve the required bend radii without deformation.
-
Bending, Cutting & End Forming: Automated bending and cutting to length, followed by any necessary secondary operations (flattening, piercing, threading).
-
Surface Treatment: Application of specified finish—powder coating, e-coating, or plating—in controlled batches for uniform quality.
-
Rigorous Inspection: 100% visual inspection, plus periodic dimensional checks using templates or CMMs to verify critical bends, lengths, and angles.
