This custom stainless steel duct is designed for integration into
EV battery separator production lines. It is precision sheet metal
machined for superior corrosion resistance, air tightness, and
dimensional accuracy—critical for assembly in Japan and final
delivery to Tesla EV battery pack factories.
Overview
Our stainless steel duct is the primary airflow conduit within EV
battery separator equipment, ensuring consistent environmental
control and particle-free operation during film deposition.
Its rugged welded construction provides leak-free performance under
continuous operation, a key requirement for high-quality film
production.
Key Features
1. Made of SUS304 or SUS316L stainless steel for superior corrosion
resistance and cleanability.
2. Seamless fully welded joints ensure air tightness and structural
integrity under high-pressure airflow.
3. Precision CNC laser cutting and bending ensures dimensional tolerances of ±0.5 mm.
4. Smooth inner surface minimizes particle accumulation and is easy to clean in a cleanroom environment.
5. Customizable inlet/outlet flanges and mounting brackets for Tesla’s Japanese factory-assembled units.
6. Optional shock absorbers, inspection ports, and access panels with gaskets for maintenance without downtime.
