Product Description

Medium Density Fibre Board Continuous Press Production Line

Product Overview

The High-Capacity & High-Efficiency MDF Continuous Press Production Line represents the pinnacle of technological advancement in MDF manufacturing. It abandons the traditional batch-type pressing cycle and instead employs steel belts to continuously convey the mat through a high-temperature, high-pressure press tunnel, enabling genuine 24/7 non-stop, flow-line production. This model completely eliminates non-pressing idle time, which is the fundamental guarantee for achieving the "high-capacity and high-efficiency" goal.

Core Technical Features

Continuous Press Technology: The core utilizes a continuous press (e.g., ContiRoll). The mat is continuously fed through the press between two high-precision endless steel belts. Pressure and temperature are precisely controlled across different zones, creating an optimal curing profile that ensures quality while achieving maximum production speed (infeed speeds can exceed 1000 mm/s).

High-Capacity & High-Efficiency Design: The line is designed for annual capacities ranging from 150,000 m³ to over 600,000 m³. Its high efficiency is reflected in lower energy consumption per unit product, near-zero press cycle time, and reduced labor requirements due to high automation.

Superior Thickness Control & Panel Uniformity: The continuous pressing process results in exceptionally uniform density distribution and thickness tolerance (as low as ±0.15mm) across the length and width of the panel. Product quality stability and consistency far surpass that of batch-pressed boards.

High Automation & Intelligent Control: The complete line integrates advanced DCS/PLC control systems and MES. It enables fully automated control and data traceability from raw material blending and process parameters to final grading, which is key to realizing "lights-out" manufacturing and labor cost reduction.

Excellent Energy Efficiency: The continuous press utilizes thermal oil or steam heating with high thermal efficiency. Its continuous operation mode avoids the significant energy losses associated with the frequent opening and closing of traditional presses, leading to substantial overall energy savings.

Production process

This highly automated line is a continuous process centered around a Continuous Press, transforming wood raw material into finished MDF boards non-stop.

The 5-stage flow:

1. Raw Material Preparation: Wood is chipped, screened, and refined into fibers in a Defibrator.

2. Blending & Drying: Fibers are uniformly mixed with resin and dried in a Pipeline Dryer.

3. Mat Forming: Dry fibers are formed into a uniform mat by a High-Speed Former and pre-compressed.

4. Continuous Hot Pressing (Core): The mat enters the Continuous Press, where it is cured under heat and pressure while being carried continuously by steel belts. This non-stop process is the key to high output and efficiency.

5. Finishing: The continuous board is cooled, cut, sanded, sorted, and automatically stacked/packaged.

In a nutshell: It's like making an endless "wafer," seamlessly converting Chips → Fibers → Mat → Continuous Pressing → Finished Boards, achieving unity of speed, volume, and quality.
