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
1
Decoiling & Dual-Strip Forming
Raw metal coil is uncoiled and simultaneously formed into two identical pre-profiles
2
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
3
Hydraulic Cutting
The continuous sealed profile is cut to exact specified lengths
4
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 delivery?
We deliver the entire coordinated system, install it, and train your workers. You will be producing qualified, high-quality blades within 3 days of delivery.
What ensures the blades are 100% airtight?
Our unique dual-strip hemming technology creates a seamless, permanent seal that outperforms manual processes, ensuring zero fire inspection failures.
How does the machine save labor and double output?
The machine processes two strips simultaneously to deliver 60% higher output than single-strip machines. Only one operator is required, replacing 5 to 6 manual workers and cutting labor costs by 70%.
What is the lifespan and maintenance requirement of this machine?
Built with premium CR12MOV steel rollers and a vibration-free heavy-duty frame, the machine is designed to run reliably for over 15 years with only basic, routine maintenance.
What are the steps involved in the production process?
The integrated process consists of four automated stages: Decoiling & Dual-Strip Forming, Edge Hemming & Sealing, Hydraulic Cutting, and final Hydraulic Punching.
