With the accelerated urbanization process, the distance between highways, overpasses, and residential areas is increasingly shrinking, making traffic noise control a top priority in public welfare projects. As the core production machine for sound barriers (noise-reducing panels), the Highway Sound Barrier Panel Rolling Forming Machine has emerged accordingly.
This is not merely a cold bending forming machine, but an all-in-one fully automated intelligent production line integrating automatic punching, high-precision rolling forming, and fixed-length cutting. Specifically designed for manufacturing metal sound-absorbing and soundproof panels for highways and railways, the equipment can process metal coils such as galvanized sheets and aluminum plates through continuous cold bending to produce high-strength noise-reducing panels with louvered holes, micro-perforations, or wave patterns in a single pass, completely transforming the inefficiency and precision shortcomings of traditional single-machine production.
Application Scenario: Quiet protection is provided at all accessible road and bridge crossings
• Along highways and railways:
Designed to address the characteristics of high vehicle speeds and broad noise frequency spectrums, the heavy-duty plug-in sound barriers effectively block the spread of traffic noise toward residential areas and schools on both sides.
• Urban Viaducts and Interchanges:
The equipment can produce top curved sound barriers with both light-transmitting and noise-reducing functions, purifying urban high-altitude noise without affecting bridge deck lighting.
• Rail Transit and Intercity Railways:
Meets the stringent requirements for high-strength noise reduction panels and resistance to pulsating wind pressure at high-speed rail tunnel entrances and embankment sections.
• Industrial Plant and Equipment Noise Reduction:
It can also produce soundproofing panel enclosures for wrapping large industrial equipment, cooling towers, and substations, achieving noise source control in industrial settings.

Core feature: Born for noise reduction, winning with precision
1. Unique high-precision punching system
The core of a sound-absorbing board lies in “soundproofing”, and the arrangement and accuracy of the holes determine the sound absorption coefficient. The equipment is equipped with a servo driven punching device, which can accurately punch out various hole types such as micro holes and louver holes. The hole spacing error is controlled within ± 0.2mm, ensuring that the board meets the noise reduction requirements while having excellent water and dust conductivity, and the hole arrangement is beautiful and uniform, enhancing the visual texture of the project.
2. Modular Cold Bending Forming Unit
High quality chromium steel quenched and finely ground rolling rolls are used, with high surface smoothness and never scratching the surface of the plate. The unique modular box structure allows for quick mold replacement according to customer needs, producing sound-absorbing panels in various cross-sectional shapes such as flat, wavy, and plug-in, achieving multi-purpose use and meeting the bidding parameter requirements of different road projects with ease.
3. Fully closed-loop servo cutting with fixed length
Say goodbye to the cumulative error caused by mechanical limit. The equipment adopts full servo motor drive and PLC control system, combined with hydraulic/flying saw cutting device, which can track the production line speed in real time. Whether it is a 3-meter standard board or a customized length of a special shape, there is no need to stop the machine when cutting, the incision is smooth and free of burrs, and the length accuracy is as high as ± 0.5mm, greatly improving installation efficiency.
4. High durability surface treatment adaptability
Considering that highway guardrails are susceptible to erosion from rainwater and salt spray, our molding machine has specially optimized the roller gap and compression force, perfectly adapting to the molding of various high anti-corrosion substrates such as hot-dip galvanizing, zinc aluminum magnesium alloy, and color coated sheet. During the production process, the coating is not damaged or peeled off, ensuring that the finished sound-absorbing board has an outdoor service life of over 20 years from the source.
5. Fully automatic PLC integrated control
Equipped with a large-sized touch screen human-machine interface, supporting one click changeover, fault self diagnosis, and remote operation and maintenance. One operator can easily control the entire process, greatly reducing labor costs. The production efficiency can reach more than three times that of traditional equipment, and the daily output can easily exceed 2000 square meters.
