Continuous 80-500mm diameter output eliminates waste and manual joining operations

PLC Automation

Delta touchscreen control enables quick diameter changes, 0-5 m/min speed, consistent quality

Dual Standard Compatibility

CN and EU lock seam configurations serve domestic and international markets from one line

Compact Installation

2300×800×1250mm footprint, 450kg weight fits existing workshops without reinforcement

Custom Roller Profiles

Customizable forming rollers enable product differentiation in competitive duct markets

Low Power Operation

3kW motor consumption maintains reliable throughput while minimizing operating costs

Key Features

The machine feeds and forms two layers of aluminum or stainless steel strip simultaneously, producing ducts with enhanced mechanical strength and thermal performance. This eliminates the need for a secondary wrapping process and reduces your per-unit labor cost.

A Delta PLC paired with a touchscreen panel governs strip feed rate, forming speed, and seam lock engagement. Operators can store parameters for each duct diameter, enabling fast changeovers and consistent wall geometry across production runs.

With an 80–500 mm diameter range and compatibility with strip thicknesses from 0.05 to 0.20 mm, the PAD-300 covers the majority of flexible duct sizes used in residential HVAC, commercial ventilation, and industrial exhaust applications — all on one machine.

At just 2300 × 800 × 1250 mm, the machine occupies minimal floor space. The 3 kW drive motor keeps energy consumption low, making it a practical choice for small-to-medium duct manufacturers scaling up production without heavy capital investment.

The forming rollers support both Chinese and European lock seam standards. This dual compatibility lets export-oriented manufacturers fulfill orders for multiple regions without retooling, shortening lead times for international customers.
