Hanghzou IUWON Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of square downpipe roll forming machine in China. With abundant experience, we warmly welcome you to buy high quality square downpipe roll forming machine from our factory. Good service and reasonable price are available.
Multi-Station Precision Forming
The machine features 18 to 22 forming stations (depending on profile complexity). Each station uses rollers CNC-machined from High-Grade 45# Steel or Cr12 Mould Steel, vacuum heat-treated and finished with a 0.05mm hard chrome plating. This progressive forming method ensures the metal maintains its structural integrity and protective coating while achieving sharp, clean corners.
Integrated Leak-Proof Seaming System
To ensure a completely watertight product, our machine incorporates an automatic longitudinal seaming unit. This unit creates a high-pressure "lock-seam" that is significantly more durable than traditional riveting. The result is a seamless-looking square pipe that can withstand heavy water pressure and thermal expansion without joint failure.
Intelligent PLC Automation & Flying Cut
Powered by a Siemens or Panasonic PLC control system, the machine offers fully automated operation.
Flying Hydraulic Cut: Features a non-stop cutting mechanism that allows for continuous production without slowing down the line.
Precision Length: Encoder-based measurement ensures a length tolerance of within ±1.0mm.
Data Memory: The system can store multiple production recipes, allowing for rapid switching between different order lengths and quantities.
Heavy-Duty "H-Beam" Chassis
The machine base is constructed from 350mm to 400mm H-beam steel with 18mm-20mm thick wall-plate side frames. This massive construction absorbs vibration and prevents frame warping over time, ensuring that the rollers remain perfectly aligned even after years of high-volume production.
Auxiliary Elbow Integration
Every square downpipe machine is designed to produce profiles that are 100% compatible with our Square Pipe Elbow Bending Machine. This allows manufacturers to produce the "offsets" and "bends" required for complex building eaves and corners directly from the pipes produced on the line, ensuring a perfect fit every time.
FAQ
Q: What is the difference in performance between square and round downpipes?
A: Square downpipes typically offer a larger cross-sectional area, allowing them to handle higher volumes of water during heavy rainfall. Architecturally, they are often preferred for modern or commercial buildings for their clean, linear look.
Q: Can I adjust the machine to make different square sizes?
A: Because roll-forming requires fixed roller positions for precision, each machine is usually dedicated to one specific profile. However, we can design "dual-level" or "cassette" machines if you need to produce two different sizes on a single frame.
Q: How does the machine handle pre-painted (colored) steel?
A: Our rollers are polished to a mirror finish and chrome-plated. This, combined with our progressive forming design, ensures that the paint or protective coating on your coils will not be scratched or cracked during the forming process.
Q: Is the cutting process "Stop-and-Cut" or "Flying-Cut"?
A: We offer both. Our standard model uses a high-precision hydraulic post-cut (stop-and-cut), while our high-speed versions feature a "Flying Cut" system that allows the machine to maintain its speed while the blade moves with the material.
Q: What power supply is required for this machine?
A: The standard configuration is 380V / 50Hz / 3-Phase. However, we can customize the motors and electrical components to match your local industrial voltage (e.g., 220V, 415V, or 440V) at no extra cost.
