Welcome to Mana Precast
A noise barrier is an acoustic panel placed between a noise source and a receiver to reduce noise pollution. These barriers are made from materials that absorb, block, or combine both functions to effectively mitigate noise. The principle is simple: inserting an obstacle between the sound source and the receiver causes significant attenuation of sound waves, reducing noise impact in the target area.

Durability and Stability: Concrete is a robust and long-lasting material that effectively isolates noise.
Long Lifespan and Low Maintenance: Concrete barriers require minimal upkeep and offer an extended service life.
Eco-Friendly Material: Concrete is environmentally friendly and does not emit harmful substances.
Effective for Low-Frequency Noise: Concrete is highly effective in reducing low-frequency noise.
Acid and Alkali Resistance: Concrete barriers are suitable for various environmental conditions, withstanding both acidic and alkaline environments.

Mana's noise barrier moulds are engineered for optimal performance and efficiency. Key features include:
Vertical Battery Mould: Utilises the vertical battery mould technique for enhanced production line efficiency.
High Rigidity: The mould design ensures stress is uniformly eliminated, guaranteeing long-term durability.
One-Step Forming: Advanced forming technology allows for sound-absorbing, emitting, and filling holes to improve acoustic properties.
Automatic Core Pulling and Filling: The automatic core pulling and filling mechanism enhances overall productivity.
Hydraulic System for Precision: The hydraulic system used for opening and closing the moulds ensures high geometric precision of the components.
Special Sealing and Vibration Technology: Achieves superior raw concrete finishes, enhancing the overall quality of the noise barrier.
