The global transition toward electric mobility has fundamentally redefined quality and safety requirements throughout the automotive supply chain. Among the most critical components in electric vehicles are battery housings, whose structural integrity and cleanliness directly impact battery performance, reliability, and safety.

Meeting these demanding requirements calls for advanced technical cleaning solutions capable of delivering exceptional cleanliness levels while maintaining the productivity required by modern high-volume manufacturing. To address these challenges, Firbimatic has developed state-of-the-art closed-loop solvent cleaning systems specifically engineered for the automotive and e-mobility industries.

Why Technical Cleaning Is Critical for Automotive Battery Housings

Battery housings protect and support the battery modules throughout the vehicle's entire service life. These precision-engineered metal components must guarantee perfect insulation and mechanical reliability under demanding operating conditions.

Even microscopic contaminants—including machining chips, metallic particles, abrasive residues, or conductive dust—can become a serious risk. Particles measuring only a few microns may lead to micro short circuits, interfere with battery cooling systems, accelerate component degradation, or ultimately compromise the performance and safety of the entire battery pack.

For this reason, the world's leading automotive manufacturers and battery suppliers implement strict contamination control procedures based on ISO 16232, the international standard for cleanliness of automotive components. Achieving the cleanliness levels required by ISO 16232 demands highly engineered cleaning technology capable of completely removing particulate contamination, machining residues, and stamping oils.

Firbimatic's Solution: The SFK Closed-Loop Solvent Cleaning Series

To meet the increasingly demanding cleanliness specifications of battery manufacturing, Firbimatic has developed the SFK Series, a range of fully enclosed vacuum cleaning systems designed for hydrocarbon and modified alcohol solvents.

Operating in a hermetically sealed closed-loop process, these systems combine outstanding cleaning performance with environmental sustainability, solvent recovery, operator safety, and low operating costs.

The effectiveness of this technology is demonstrated by recent international installations of the SFK 200 V, selected by a leading global supplier serving some of the world's largest battery manufacturers and automotive OEMs. These projects confirm the reliability and scalability of Firbimatic technology for high-volume industrial production.

SFK 200 V: Engineered for High Productivity and ISO 16232 Compliance

The SFK 200 V has been specifically designed to combine intensive cleaning performance with the throughput required by modern automotive production lines.

Its key technical features include:

• Large Cleaning Capacity: Approximately 1.300-liter cleaning chamber combined with 5.000 liters of total solvent storage, providing ample capacity for large automotive battery housings.
• Continuous Solvent Regeneration: Dual distillation system capable of processing up to 1.700 liters of solvent per hour, continuously removing oils and emulsions while maintaining maximum solvent purity.
• High-Power Ultrasonic Cleaning: Up to 18 kW ultrasonic power, generating intense cavitation capable of removing particles trapped inside welds, cavities, and complex geometries, helping manufacturers achieve ISO 16232 cleanliness requirements.
• Maximum Productivity: Optimized hydraulic circuits enable extremely short cycle times, processing up to 350 battery housings every 10 minutes, while fully automated loading and unloading systems minimize downtime.
• Continuous Operation: Advanced filtration systems with automated maintenance significantly reduce manual intervention and maximize machine availability.
