Turnkey Dual-Strip Hollow Damper Blade Production Line | China Suppliers for Integrated HVAC Factory Solutions
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.
Frequently Asked Questions
How fast can we start production after the machine is delivered?
Thanks to our true turnkey delivery service, we handle the installation and provide comprehensive training for your operators. You will be able to start producing qualified HVAC damper blades within just 3 days of delivery.
What technology ensures the damper blades are 100% airtight?
Our machine utilizes a unique dual-strip hemming technology that folds and seals the edges of the metal profiles permanently. This creates a seamless seal that consistently passes strict fire and airtightness inspections.
How does the machine double production output while saving labor?
The machine processes and forms two profiles simultaneously, yielding 60% higher output than single-strip machines. Additionally, the entire process is automated, requiring only one operator to monitor the line instead of 5-6 manual workers.
What materials are used to guarantee a 15+ year service life?
The rollers are engineered from premium CR12MOV steel, quenched to a hardness of HRC57-59°, and precision machined after heat treatment. This, combined with a heavy-duty steel frame, ensures stable operation for over 15 years with minimal maintenance.
What are the main stages of the standard production process?
The standard process consists of four automated stages: 1. Decoiling & Dual-Strip Forming, 2. Edge Hemming & Sealing, 3. Hydraulic Cutting to specified lengths, and 4. Hydraulic Punching for mounting and pivot holes.
