The Highway Noise Barrier Sound Panel Roll Forming Machine is an integrated automatic cold bending production line specifically designed for the continuous production of highway sound barrier suction and insulation boards. It is not a simple standalone combination, but a combination of automatic unwinding, high-precision leveling, servo punching (micro holes/louver holes), roll forming, cutting to length, stacking and stacking. It can even be combined with sound-absorbing cotton and backboards online, directly outputting finished sound-absorbing boards that can be used for installation.

The equipment can handle a wide range of raw materials, including galvanized sheet, aluminum sheet, color coated sheet, aluminum magnesium manganese alloy sheet and other metal coils. Whether you need circular hole micro perforated panels, louvered sound-absorbing panels, or wavy or flat soundproof panels, you only need to replace a small number of molds to flexibly switch on the same line, truly achieving multi-purpose and flexible production on one machine.

Core feature: Redefine efficiency and precision with strength

1. Full process automation, board output in seconds
Starting from the feeding of the coil, unwinding, leveling, punching, forming, and cutting are all done in one go. Equipped with imported brand PLC and touch screen CNC system, operators only need to input the production quantity and length, and the equipment can run continuously and automatically. It can produce finished boards of several meters or even more than ten meters per minute, greatly reducing the delivery cycle of orders and easily responding to emergency engineering needs.

2. The integration of micropores and molding processes results in outstanding noise reduction performance
The core of a sound-absorbing board lies in its acoustic performance, and the key to acoustic performance lies in the number, aperture, arrangement, and shape accuracy of the micro pores in the board. The proprietary servo punching system of this equipment can achieve high-speed punching of micro holes with a diameter of less than 0.5mm, with uniform hole spacing and no burrs. Combined with high rigidity roll forming, it ensures that the hole shape and bending curvature of each sound-absorbing board are highly consistent with the design value, allowing sound waves to form high-efficiency energy dissipation when passing through micro holes, ensuring excellent sound absorption and noise reduction coefficient, and meeting the strict acoustic standards of highway sound barriers.

3. Multi layer composite in one step, eliminating the need for secondary processing
For plug-in sound-absorbing panels, the molding line can integrate processes such as automatic glue spraying, sound-absorbing cotton filling, and metal backplate covering. In the main molding process, the three-layer structure of “panel+sound-absorbing material+backboard” is directly completed, completely eliminating the need for manual or separate composite equipment, ensuring that each board is full and void free inside, improving the yield and production efficiency, while greatly reducing workshop land occupation and transportation costs.

4. High rigidity heavy-duty rack, stable and long-lasting
The entire line adopts a wall mounted welded frame, which has undergone stress relief annealing treatment and has high strength and deformation resistance. The precision rolling mill is made of high-quality alloy steel (such as Cr12MoV), which has undergone CNC machining, vacuum heat treatment, and hard chrome plating. It has excellent wear resistance, ensuring stable forming accuracy even after long-term service, and building a solid and reliable quality defense line for you.

5. Intelligent length measurement and online detection, zero waste
The equipment is equipped with high-precision encoder length measurement and closed-loop flying saw/hydraulic cutting system, with cutting length error controlled within ± 1mm. Combining online flatness monitoring and mold life warning, automatic shutdown alarm is triggered in case of abnormalities, reducing the scrap rate to the lowest possible level and truly achieving the goal of ‘producing good products’.

Application scenario: Extend tranquility to every road

• Manufacturing of sound barriers for highways and railways
This is the main battlefield of the equipment. The produced sound-absorbing panels are directly used for sound barrier projects on both sides of highways and high-speed railways, absorbing the mid to high frequency noise generated by the friction between wheels and air, and protecting villages, schools, and ecological areas along the line. Bulk supply of sound barrier prefabrication factories or large road and bridge construction groups is a powerful guarantee for production capacity and quality in centralized procurement bidding.

• Sound insulation for urban elevated roads and rail transit
The noise reduction requirements for urban elevated bridges, light rail, and subway ground sections are equally urgent, and the appearance is more diverse. The equipment can quickly switch to produce more decorative sound absorbing and insulating panels such as curved and bent shapes, which, combined with urban landscape design, make the soundproofing facilities both practical and beautiful.

• Municipal roads and noise reduction enclosures in factory areas
Industrial noise sources such as urban main roads, cooling towers, substations, and air conditioning outdoor units near residential areas require a large number of transparent or semi transparent soundproof enclosures. These types of projects often have multiple order specifications, small batch sizes, and urgent delivery times. Flexible production molding lines are just right to showcase their capabilities and quickly respond to diverse market demands.
