Perforated Aluminum Flexible Duct Machine Machine

The multi-stage forming line operates at adjustable speeds up to 5 m/min with automatic length cutting, delivering consistent output while minimizing operator intervention. This continuous process eliminates stop-start cycles common in batch-type machines, translating directly into higher daily throughput.

With a diameter range of 80–500 mm and compatibility with both aluminum and stainless steel strip from 0.05 to 0.20 mm thick, this machine covers the full spectrum of flexible duct sizes demanded by HVAC, exhaust, and industrial ventilation markets. Over 300 mould sets are available from NTBOBO for customized configurations.

A Delta PLC with touchscreen display gives operators direct control over speed, length, and forming parameters. Mould changes are designed for speed — switching between 4-wave, 6-wave, and 8-wave profiles requires no specialized tools, keeping changeover times short and production schedules flexible.

Finished ducts compress to a 1:4 ratio, meaning a 3-meter duct occupies roughly 750 mm of shipping space. For manufacturers exporting to multiple markets, this compression ratio substantially lowers container costs and warehouse requirements.

Built on a painted steel frame with a total motor power draw of just 2.25 kW, the machine delivers industrial-grade output at low energy consumption. The robust frame and protective housing are engineered for sustained daily operation in factory environments, backed by NTBOBO’s one-year warranty with free replacement parts for quality-related issues.
