Turnkey Dual-Strip Hollow Damper Blade Production Line | China Suppliers - Integrated HVAC VCD Louver Blade Factory Equipment
Why choose this machine?
True turnkey delivery, start production in 3 days
No more wasting months integrating separate machines from different suppliers. We deliver the entire coordinated system, install it, and train your workers. You’ll be producing qualified blades within 3 days of delivery. No more production delays from incompatible equipment.
100% airtight blades that pass every fire inspection
The unique dual-strip hemming technology creates a seamless, permanent seal that no manual process can match. Our customers report zero inspection failures after switching to this line. No more rejected orders, no more costly reworks, no more damage to your reputation.
Double the output, half the labor
This line produces two blades at the same time, delivering 60% higher actual output than single-strip machines. Only one operator is needed to monitor the entire process, replacing 5-6 manual workers. Your labor costs will drop by 70% while production capacity doubles.
Built to last 15+ years with minimal maintenance
All rollers are made of premium CR12MOV steel, quenched to HRC57-59° and precision machined after heat treatment. The heavy-duty steel frame eliminates vibration even at full speed. This line will run reliably 8 hours a day, 6 days a week for over 15 years with only basic maintenance.
Standard Production Process
- Decoiling & Dual-Strip Forming: Raw metal coil is uncoiled and simultaneously formed into two identical pre-profiles.
- Edge Hemming & Sealing: The two pre-profiles are fed into the hemming machine, where edges are folded and precision-sealed together to form a single robust hollow blade.
- Hydraulic Cutting: The continuous sealed profile is cut to exact specified lengths.
- Hydraulic Punching: All pivot holes and mounting holes are automatically punched with high accuracy, preparing blades for final assembly.
