Stainless steel sheet metal 2B side air duct custom processing

Product Specification

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.
