I. Product Overview: Definition & Core Value
The High-Production & High-Efficiency Continuous Press for Particleboard, specifically referring to modern presses employing Continuous Flat Pressing (CFP) technology, is the "heart" of the particleboard production line. In contrast to traditional discontinuous multi-opening hot presses, it enables the uninterrupted, continuous hot pressing of the particle mat, making it the core technological equipment for achieving high output, high efficiency, and superior quality in particleboard production.
Its core value lies in: revolutionizing "batch production" into "process production", akin to upgrading from a handicraft workshop to a modern assembly line. This results in a qualitative leap in capacity, quality, cost, and flexibility.
II. Core Working Principle: The Secret of Continuous Flat Pressing
A continuous press is not merely a "big clamp" but a precision, elongated "tunnel of pressure and heat". Its working principle is as follows:
1. Mat Infeed: The continuous, pre-pressed mat is fed into the press through the inlet.
2. Steel Belt Carrying & Conveying: The mat is sandwiched between two massive, endless heat-resistant steel belts. These belts act as carriers, transporting the mat through the entire length of the press.
3. Precise Application of Pressure & Heat:
Pressure System: A large number (up to hundreds) of independent hydraulic cylinders are arranged inside the upper part of the press. They apply pressure to the upper steel belt via a long pressure plate. These cylinders are divided into multiple pressure zones, allowing the system to precisely program and control the pressure in each zone, creating an optimized pressure profile. As the mat travels, it experiences a smooth transition from high to low pressure from inlet to outlet, facilitating air removal, achieving optimal density distribution, and minimizing internal stress.
Heating System: Similarly, the heating platens of the press are divided into multiple temperature-controlled zones. Via thermal oil circulation, they provide a precise temperature profile for the mat's curing. Typically, higher temperatures are needed at the inlet to initiate resin curing, and lower temperatures at the outlet to stabilize the board.
4. Forming & Output: Clamped between the steel belts, the mat moves at a constant speed through this "pressure-heat tunnel," gradually completing the curing process as it travels. The output from the press exit is a continuous, fully cured ribbon of particleboard.
III. Key Components
1. Steel Belt System:Carries and conveys the mat, transfers pressure and heat.
Requirements: Extremely high surface finish, heat resistance, fatigue strength, and dimensional stability. It is a key consumable critical for ensuring surface quality and operational reliability.
2. Hydraulic System:Provides powerful, stable, and precisely controllable pressure for the entire press.
Features: Utilizes servo-control and proportional valve technology for zonal and sectional precise pressure control. The pressure profile can be flexibly adjusted based on product thickness and density requirements.
3. Heating System:Provides the heat required for mat curing.
Method: Typically uses a thermal oil circulation system that transfers heat uniformly to the steel belts via the upper and lower heating platens, which then conduct it to the mat. Temperature control accuracy can reach ±1.5°C.
4. Frame & Roller System:Supports the enormous weight and pressure of the press and houses the steel belts and numerous rollers.
Design: Manufactured from high-strength steel, optimized via Finite Element Analysis (FEA) to ensure minimal deformation under long-term extreme loads. A precision roller system supports and tensions the steel belts, ensuring their smooth operation.
5. Control System:The "brain" of the press.
Capabilities: Integrated into the plant's main control system, it monitors and automatically regulates thousands of parameters in real-time, including pressure, temperature, speed (output), and thickness. It possesses advanced functions such as automatic width adjustment (for producing different board widths), fault diagnosis, wear monitoring, and maintenance alerts.

Ⅵ. What is meant by "High-Production & High-Efficiency"?
The excellence of the production line was defined from two aspects: "output quantity" and "input-output ratio".
1. "High-Production" - Refers to Extremely High Production Capacity
"High-Production" focuses on "volume" – how much product can be manufactured per unit of time.
Continuous, Uninterrupted Production Mode: This is the foundation of high production. Traditional multi-opening presses operate in a "batch" or "discontinuous" mode, requiring a cycle of "loading → closing → pressing → opening → unloading," each with significant idle time. In contrast, the continuous press operates like a never-ending tunnel; the mat continuously enters, and the finished board continuously exits, eliminating all idle waiting time.
Very High Production Line Speed: The line speed of a continuous press can typically reach 800 - 1500 millimeters per second. This means nearly a meter or more of finished board is produced every second.
Massive Annual Output: Thanks to the continuous mode and high-speed operation, the annual capacity of a single production line can easily exceed 200,000 cubic meters, with top configurations even surpassing 500,000 cubic meters – a level unattainable by traditional multi-opening presses.
In short, "High-Production" maximizes output capacity through [continuous operation + high speed].
2. "High-Efficiency" - Refers to Extremely High Comprehensive Efficiency
"High-Efficiency" focuses on "quality" and "benefit" – how to produce more and better products with less input. It is reflected in multiple aspects:
High Energy Efficiency:
Traditional presses require repeated heating and cooling of massive platens, with significant heat loss during idle periods.
The continuous press maintains a constant temperature, resulting in extremely high thermal efficiency. Energy consumption per unit of product is 25% - 40% lower than that of multi-opening presses.
High Production Efficiency:
A high degree of automation minimizes human intervention, ensures a stable production rhythm, and maximizes equipment utilization.
High Raw Material & Consumable Efficiency:
Precise glue application control systems ensure optimized resin usage, reducing waste.
The produced boards have uniform density and stable quality, leading to very low rejection and defect rates, thereby improving the yield from raw materials.
High Labor Efficiency:
The entire production line requires only a few personnel to monitor it from a central control room, significantly reducing labor costs and the risk of human error.
In short, "High-Efficiency" minimizes costs and maximizes benefits through [energy-saving design + automation + precise control].
