Automotive Industry Cleanroom Solutions: NEV Battery Assembly & High-End Painting

I. New Energy Vehicle (NEV) Battery Pack Assembly Solutions

1. Cell Stacking & Module Assembly

   • ISO Class 6-7 Cleanrooms: Modular cleanrooms with FFUs to maintain ≤35,200 particles/m³ (≥0.5μm), preventing metal dust contamination during laser welding.

   • Anti-Static Laminar Flow Hoods: Provide ISO Class 5 zones for electrolyte filling and terminal sealing, reducing short-circuit risks.

   • Air Showers: Remove 99.97% particles from operators’ clothing before entering dry room environments (<1% RH).

2. Battery Encapsulation & Testing

   • Sealed Pass Boxes: Transfer battery casings and thermal interface materials without exposing them to ambient humidity.

   • Negative Pressure Chambers: Isolate thermal runaway testing areas with HEPA filtration to capture toxic fumes.

3. ESD-Protected Cleanrooms

   • Conductive flooring + ionizing FFUs to dissipate static (<100V) during sensitive BMS (Battery Management System) integration.

II. Premium Automotive Painting Booth Solutions

1. Base Coat & Clear Coat Application

   • ISO Class 8 Painting Booths: FFUs with 99.995% HEPA filters to achieve ≤3,520,000 particles/m³, eliminating fisheyes and orange peel defects.

   • Temperature/Humidity Control: Modular cleanrooms maintain 22±1°C and 60±5% RH for optimal paint adhesion.

2. Robot Spray Zones

   • Unidirectional Laminar Flow: Vertical FFU arrays create downward airflow (0.3-0.5m/s) to suppress overspray particles.

3. Paint Storage & Mixing

   • Positive Pressure Cleanrooms: Prevent dust ingress into solvent-based paint storage areas via FFU pressurization.

4. Post-Painting Inspection

   • Air Shower Pass-Throughs: Transfer painted components to dust-free inspection rooms without contamination.

III. Core Competitive Advantages

• Industry Compliance: Meet IATF 16949, ISO 14644, and VDA 19.1 cleanliness standards.

• Explosion-Proof Design: ATEX-certified FFUs for solvent-rich painting environments.

• Energy Savings: 40% lower operational costs via variable airflow FFU controls vs. traditional HVAC.

• Scalability: Modular cleanrooms expandable for EV production line upgrades.
