Zhongtuo Highway Sound Barrier Panel Roll Forming Machine Acoustic Noise Barrier Machine

With the rapid development of highways, railways, and urban infrastructure, noise pollution has become a major environmental concern. Sound barrier panels are widely installed along highways, railways, and urban roads to effectively reduce traffic noise and improve the surrounding living environment.

To meet the growing demand for high-quality acoustic panels, the Highway Sound Barrier Panel Roll Forming Machine provides an efficient and automated manufacturing solution. This advanced production line is designed to produce perforated noise barrier panels with high precision, stable performance, and excellent surface quality.

What Is a Sound Barrier Panel Roll Forming Machine?

The Sound Barrier Panel Roll Forming Machine is a specialized production line designed to manufacture acoustic noise barrier panels used in highway, railway, and urban infrastructure projects.

The machine forms metal sheets into sound-absorbing panels through a continuous roll forming process. Combined with a hydraulic punching system, it can produce perforated panels that enhance sound absorption performance.

This automated system significantly improves production efficiency while ensuring consistent panel quality.

Production Process of Acoustic Sound Barrier Panels

The complete Perforated Sound Barrier Panel Production Line operates through the following steps:

1. Hydraulic Decoiler and Loading Cart
   Automatically loads and uncoils steel coils for continuous feeding.

1. Leveling Machine
   Flattens the metal sheet to ensure precise forming and punching accuracy.
2. 160T Hydraulic Punching Press
   Equipped with customized perforation dies to create acoustic holes that enhance noise absorption.

1. Roll Forming Machine
   Shapes the perforated metal sheet into the required sound barrier panel profile.
2. Hydraulic Bending and Cutting Device
   Performs precise cutting and bending according to panel length requirements.
3. Automatic Receiving Table
   Collects finished sound barrier panels for easy stacking and transportation.

This fully automated production line reduces manual labor while ensuring high production consistency.

Fully Automatic Operation

With PLC control and touch screen interface, the machine can run automatically, reducing labor costs and increasing production stability.

Technical Specifications

Advantages of Sound Barrier Panels

Sound barrier panels can achieve an average sound insulation performance of up to 36dB, effectively reducing traffic noise

With an average sound absorption coefficient of 0.85, perforated panels combined with acoustic materials provide excellent noise control.

The panels are resistant to water, UV radiation, and temperature changes, ensuring long-term stability in outdoor environments.

The internal sound-absorbing material often uses ultra-fine glass wool, which is non-combustible and compliant with fire safety standards.

Prefabricated panels allow fast installation, easy replacement, and convenient maintenance.

Applications of Noise Barrier Panels

Sound barrier panels produced by this machine are widely used in:

• Highway sound barriers
• Railway noise barriers
• High-speed rail acoustic walls
• Urban road noise control systems
• Industrial noise protection projects

These systems help protect residential areas, schools, and hospitals from traffic noise pollution.
