Automotive Waterproof Nut System Solution | IATF 16949 & PPAP for Battery & ECU Dynamic Sealing
1.Waterproof nuts Quick Detail
Automotive applications demand extremely high standards for sealing fasteners: they must withstand long-term vibration at 10-2000Hz, temperature cycling from -40°C to +125°C, and potential exposure to condensation, salt spray, and lubricants. Our Waterproof Nuts are developed and controlled strictly under the IATF 16949 system, with material selection, sealing design, and production processes all prioritizing the reliability and consistency required by the automotive industry. We understand the requirements of PPAP (Production Part Approval Process) and can provide corresponding supporting documentation, making us a reliable partner for your automotive sealing connection solutions.
2.Waterproof nuts tProduct Description
In the automotive industry, the failure of a single connection point can impact the safety or functionality of the entire vehicle. We conduct in-depth analysis of the sealing requirements of different areas of the vehicle: battery packs require extremely high dust and water resistance ratings (IP67/IP69K) and electrical safety; motor controllers need to withstand high heat loads and coolant risks; and body domain controllers must withstand the impact of high-pressure water jets used in car washes. Our solutions not only provide static seals but also undergo rigorous sealing tests simulating vibration and thermal shock to ensure reliability under dynamic operating conditions. We can collaborate with your team to complete sealing testing and approval from the DV (Design Verification) to PV (Production Verification) stages.
3.Waterproof nutsroduct Features & Advantage
|
Feature |
Advantage to You |
|
Full-Process Control Based on IATF 16949 |
From incoming material inspection to production batch management, we implement strict automotive industry control standards throughout, ensuring product consistency, traceability, and continuous improvement, meeting OEMs’ mandatory requirements for the supply chain. |
|
Anti-Loosening Sealing Design for Vibration Environments |
Our sealing ring material has excellent resistance to permanent compression deformation. Combined with the firm compression between the nut and the plate, it ensures that the pressure at the sealing interface does not decrease under long-term vibration, preventing the formation of leakage channels due to fretting. |
|
Wide-Temperature Seal Materials & Validation Data |
We offer seal material options suitable for -40°C to +150°C ranges (e.g., high-performance silicone, FKM), and can perform sealing performance tests after thermal cycling and aging per standards like ISO 16750, providing supporting data. |
|
Complete Compliance & Documentation Package Support |
We can provide declarations for ROHS, REACH, ELV, key materials can have evidence of compliance with standards like USCAR, and we support the creation of IMDS reports, simplifying your vehicle compliance work. |
|
Engineering Collaboration Supporting APQP & PPAP |
For key automotive projects, we can assign a project engineer to participate in your APQP meetings and prepare the PPAP documentation package as required (e.g., dimensional reports, material certs, performance test reports, control plans). |
4.Waterproof nuts Product Specification
|
Specification Item |
Automotive-Grade Requirements & Capabilities |
Test / Validation Method |
|
Vibration Seal Test |
Maintains sealing performance, no leakage after 10-2000Hz, 3 axes, 8 hours per axis vibration. |
Per customer standard or ISO 16750-3. |
|
Thermal Shock Test |
Withstands -40°C (30min) ←→ +85°C (30min) for 50-100 cycles, sealing function remains intact. |
Common test condition, customizable. |
|
Fluid Compatibility |
After immersion in specified fluid (e.g., coolant, gear oil, brake fluid) for 168 hours @ elevated temp, the seal’s volume change and hardness change are within standard limits. |
Per ISO 1817 or customer standard. |
|
Salt Spray Corrosion |
Nut body (e.g., zinc-plated) meets red rust rating requirements after 96-240 hours neutral salt spray test. |
ASTM B117 / ISO 9227. |
|
Pressure Cycling Seal |
Evaluates sealing stability under multiple cycles of 0.5Bar ~ 1.5Bar (or customer-specified) pressure. |
Simulates cleaning, wading, or changes in internal pressure. |
|
Flammability |
Seal material options available with formulations meeting UL94 V-0 or automotive interior flammability standards. |
For battery pack or interior applications. |
5.Waterproof nuts tProduct Application
New Energy Vehicle Battery Pack: Sealing connections for module fixing plates, end plates, top covers, requiring IP67/IP69K to prevent coolant or external moisture ingress causing insulation faults.
E-Drive System: Housing sealing for Motor Control Unit (MCU), On-Board Charger (OBC), DC-DC Converter, involving harsh conditions of high temperature, vibration, and potential fluid contact.
Automotive Body & Chassis Electronics: Waterproof sealing for ADAS sensor (radar, camera) brackets, Domain Control Units (DCU), wire harness pass-throughs, ensuring reliability of advanced driver assistance functions.
Traditional Powertrain & Interior: Dust/water/oil sealing for locations like engine wire harness seals, transmission control units, sunroof drain tube connectors.
