 Core Advantages

Exceptional Acoustic Performance: The sound pressure level is consistently maintained below 75 dB(A), equivalent to the volume of a normal conversation, significantly lower than the harsh levels of traditional equipment, fundamentally improving the workshop environment.

Superior Environmental Compliance: Easily meets stringent workplace noise limits set by major global occupational health and safety regulations such as EU CE and North American OSHA, serving as a "passport" for exporting to markets with strict environmental requirements.

Enhanced Employee Well-being and Productivity: A low-noise environment effectively reduces the risk of hearing damage for operators, alleviates fatigue, increases concentration and job satisfaction, thereby reducing human error and improving overall production efficiency and stability.

Maintained High Performance: All noise reduction measures are implemented without compromising pressing precision, production efficiency, or reliability—silence and high performance go hand in hand.

 Working Principle

The fundamental working principle of this equipment is identical to that of a standard continuous flat-press: a mat is continuously fed by steel belts into a high-temperature, high-pressure zone formed by multiple hot plates, where it cures and sets under specified temperature, pressure, and speed conditions. Its uniqueness lies in the fact that all major noise sources involved in this process are systematically suppressed and isolated.

Noise control follows the principle of "reduction at the source, blocking of the transmission path":

1. Reduction at the Source: Utilizing low-noise hydraulic pumps, servo motors, and high-precision transmission components to fundamentally reduce noise generation.

2. Blocking the Transmission Path: Employing an integrated acoustic enclosure to fully encapsulate primary noise sources (e.g., hydraulic power unit, press body), and using sound-absorbing materials and vibration-damping foundations to absorb sound wave energy and block the transmission paths of vibration and sound. This achieves the effect of a noise level below 75 dB(A) at the operator's ear position.

 Workflow

The workflow of the low-noise equipment is identical in process to that of a standard continuous flat-press, but each step is performed within a noise-dampened environment:

1.  Mat Feeding: The formed mat is conveyed by the infeed system. The feed opening is typically equipped with flexible acoustic curtains to prevent noise leakage.

2.  Pre-pressing and Preheating: The mat enters the press inlet, where it is preheated and initially compacted under lower initial pressure.

3.  Main Hot Pressing and Curing: The mat moves at a constant speed through the main body of the press, undergoing heating, pressing, and adhesive curing controlled by multiple pressure and temperature zones. This is the core process stage, where all high-noise equipment (hydraulic system, drive system) operates inside the acoustic enclosure.

4.  Cooling and Setting: The pressed continuous board mat begins to cool at the outlet area, and its structure stabilizes.

5.  Board Discharge and Sawing: The board mat is discharged from the press and sent via roller conveyors to a cross-cut saw for length cutting. The sawing equipment can have separate noise reduction measures.

Throughout this entire process, the noise level perceived by operators near the equipment is consistently controlled to remain below 75 dB(A).

 Main Components

This equipment includes all the core components of a standard continuous flat-press, with specialized optimizations or additions for noise reduction:

1.  Quiet Frame: Designed with enhanced dynamic stiffness to reduce noise generated by stress-induced vibrations.

2.  Hydraulic System with Acoustic Enclosure:

      Core: Low-noise variable displacement piston pumps, large silencers, acoustically insulated oil tanks.

     Enclosure: An acoustic enclosure housing the entire hydraulic power unit, lined with sound-absorbing material.

3.  Quiet Drive System: Uses servo motors or low-noise frequency conversion motors paired with high-precision gear reducers for smooth, very quiet operation.

4.  Integrated Acoustic Enclosure: Covers the major noise source areas of the press body and drive section, constructed from composite acoustic panels, inspection windows, and sealed access doors.

5.  Low-Noise Steel Belt and Roller System: Optimized roller dynamic balance and tensioning system to reduce friction and impact noise during belt operation.

6.  Hot Plate System: Identical to standard equipment, responsible for providing heat.

7.  Vibration-Damping Foundation: Large dampers installed between the equipment base and the foundation, effectively isolating structure-borne noise.

8.  Intelligent Control System: Integrates equipment monitoring and real-time noise level display functionality, with configurable alarm thresholds.
