Flocked Springs: The Silent Solution for Automotive Interior Comfort
This product line from Zhejiang Zhengna Technology Co., Ltd. (ZENA TECH) represents a specialized innovation in automotive interior quietness. Our Flocked Springs are standard compression or torsion springs that have been meticulously coated with a layer of fine, durable nylon fibers. This unique “flocking” process, as vividly shown in the image, transforms metal springs into silent, anti-friction components, effectively eliminating the squeaks, rattles, and buzzes that compromise cabin comfort.

Product Specifications & NVH Performance
| Feature |
Technical Details |
Benefit for Automotive Interior |
| Base Spring |
High-Carbon Steel or Stainless Steel compression/torsion springs. Customizable wire diameter, coil count, and free length. |
Provides the required mechanical force and travel for functions like seat adjustment, cup holder mechanisms, or storage compartment lids. |
| Flocking Material & Process |
Electrostatically applied Nylon (PA) or Polyester fibers. Fibers are vertically aligned and bonded with adhesive for a uniform, velvety coating. |
Creates a soft, insulating barrier between metal coils and contacting surfaces (plastic, fabric, other metal), preventing direct metal-to-metal contact—the primary cause of noise. |
| Key Performance Attributes |
-
Noise Elimination: Dramatically reduces or eliminates coil-to-coil and coil-to-housing friction noise.
-
Wear Reduction: Protects both the spring and adjacent components from abrasion.
-
Dampening Effect: Can slightly dampen high-frequency vibrations.
|
Directly enhances the perceived quality and luxury feel of the vehicle interior by ensuring silent operation of moving parts. |
| Color & Aesthetics |
Standard Black (as shown). Can be customized to other colors (e.g., Gray) to match interior components. |
Provides a clean, OEM-approved appearance that blends seamlessly into the assembly. |
| Primary Applications |
- Seat Adjustment & Recliner Mechanisms
- Center Console Cup Holders & Lids
- Foldable Armrests and Storage Compartment Latches
- Sun Visor and Dashboard Component Mechanisms
- Any interior mechanism where a spring contacts another surface
|
Solves NVH (Noise, Vibration, Harshness) issues at the source, improving overall cabin acoustics. |
Why ZHENGNA Flocked Springs are Essential for Premium Interiors?
-
Targeted NVH Solution: We address a specific and common source of interior noise—spring friction. Our flocked springs are a cost-effective, drop-in solution to achieve a quieter cabin without major redesigns.
-
Engineered for Durability: The flocking adhesive and fiber material are selected for their resistance to temperature swings, humidity, and long-term wear, ensuring the noise-reduction effect lasts the vehicle's lifetime.
-
No Compromise on Function: The flocking layer is precisely controlled to be thin and uniform, ensuring it does not interfere with the spring's mechanical performance, force, or travel.
-
Full Customization & Integration: We don't just add flocking to standard springs. We design or specify the base spring to meet your exact load and travel requirements first, then apply the flocking treatment.
-
IATF 16949 Certified Process: Our manufacturing and treatment processes meet stringent automotive quality standards, guaranteeing consistency and reliability for Tier 1 and OEM suppliers.
Our Integrated Design & Manufacturing Process
-
Application Analysis: We review your mechanism to identify noise sources and recommend the optimal spring design and flocking specification.
-
Spring Design & Prototyping: In-house spring engineering and sample production to validate force and fit before flocking.
-
Precision Flocking Application: Controlled electrostatic flocking process in a dedicated environment to ensure complete, even, and adhesive coverage.
-
Performance Validation Testing: We conduct cycle testing (e.g., 50,000+ cycles) and acoustic tests to verify noise reduction performance meets targets.
