The core working principle of the continuous flat press is based on a dynamic, continuous hot-pressing process under constant temperature and pressure.
Unlike traditional "open-close-stop" batch presses, the continuous press uses an endless steel belt to continuously feed the formed mat into a high-temperature, high-pressure zone formed by multiple heated platens with a constant, narrow gap. Inside this zone, the moving mat is simultaneously subjected to precisely controlled heat and uniformly distributed pressure from the upper and lower platens. This "continuous motion replacing static cycles" allows the preheating, compression, curing, and setting processes to be completed smoothly on a continuous line, enabling high-quality, high-efficiency mass production.
The scientific basis lies in the precise control of three core parameters—pressure, temperature, and mat speed—ensuring the thermodynamic and mechanical processes experienced by the mat at every point are optimal. This results in the thorough and uniform curing of the resin, forming a stable and strong bonded structure.
The workflow can be broken down into the following consecutive stages:
1. Mat Formation and Feeding:
Dried fibers or particles mixed with resin are formed into a uniform mat on a moving conveyor by the forming station.
The mat is pre-compacted in a pre-press and then conveyed to the press inlet by a feed belt.
2. Continuous Pressing and Forming:
At the press inlet, the mat is "captured" by the circulating steel belts and drawn into the pressing gap between the platens.
Infeed Zone: The pressing gap narrows, rapidly compressing the mat and expelling air.
Main Press Zone: The mat moves at a constant speed under consistent pressure and temperature. The platens provide continuous heat, melting the resin at the core of the mat and initiating the curing process under high pressure.
Calibration Zone: As the mat progresses, the pressure is gradually reduced according to the curing stage, allowing the panel to set and release internal stress, preventing "spring-back" or deformation.
3. Cooling and Trimming:
The continuous panel strip exiting the press is conveyed through a cooling section to stabilize its dimensions and internal structure.
Finally, a high-speed synchronized cross-cut saw trims the continuous strip into individual panels of preset lengths.
This equipment is a complex mechatronic system, primarily consisting of the following core components:
1. Main Frame: A robust steel structure that supports the entire pressing system, ensuring stability and precision under extreme pressure.
2. Heated Platen System:
Multiple large steel plates with internal channels, heated by thermal oil or steam, which transfer heat to the mat.
Their surface finish is of extremely high precision, which is crucial for achieving a perfectly flat panel surface.
3. Steel Belt & Drive System:
Endless Steel Belts: High-strength alloy steel belts act as moving "molds," carrying and pulling the mat through the press. They require extreme flatness, heat resistance, and fatigue strength.
Drive Rolls & Tensioning System: The drive rolls provide forward motion, while the tensioning system ensures the belts maintain proper tension at all times, preventing slippage and misalignment.
4. Hydraulic System:
Comprises oil pumps, cylinders, control valves, and accumulators. It provides precise and stable pressure to the platens and can intelligently adjust the pressure for different process stages.
5. Heating System:
Includes a thermal oil heater/steam boiler, circulation pumps, piping, and control systems, responsible for delivering a stable, uniform heat source to the platens.
6. Automated Control System:
The Central Brain. Typically uses a PLC (Programmable Logic Controller) and an Industrial PC (HMI). It is responsible for:
Precisely controlling temperature and pressure in different zones.
Regulating the belt speed (i.e., press time).
Monitoring equipment status and diagnosing faults.
Storing and recalling production recipes for different products.
7. Infeed and Outfeed System:
Includes the feed belt, alignment devices, discharge rollers, cooling rack, and synchronized cross-cut saw, ensuring seamless integration with upstream and downstream processes.
Applicable Thickness: 1 - 40 mm
Working Pressure: Adjustable, up to [e.g., 5 MPa] (Configuration dependent)
Temperature Range: Room Temperature - 220°C (Adjustable)
Heat Source: Thermal Oil, Steam, or Electric Heating (Optional)
Control System: Fully Automatic PLC Control
Installed Power: Customized according to model and size
1. Exceptional Thickness Versatility:
A unique thickness range (1-40mm) allows a single machine to cover the entire production spectrum from ultra-thin decorative panels to standard-thickness boards, providing immense production line flexibility.
2. Precision Continuous Flat Press Technology:
Utilizes an endless steel belt and a precision-engineered hot-plate system to apply consistent, uniform pressure and temperature to the mat. This completely eliminates the "breathing marks" associated with traditional batch presses, ensuring superior dimensional stability and consistent physical properties.
3. Superior Surface & Internal Quality:
The precise temperature field control and pressure distribution system guarantee uniform heat penetration throughout the curing process. This results in high-quality panels with an exceptionally smooth, flat surface and a dense, homogeneous internal structure, ideal for direct lamination and other high-end applications.
4. Advanced Automation & Intelligent Control:
Integrated PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) systems allow for precise setting and real-time monitoring of all key process parameters (pressure, temperature, speed). The recipe storage function enables quick changeovers between different products, significantly reducing human error and downtime.
5. High Energy Efficiency:
An optimized hot-plate layout and highly efficient thermal oil circulation system maximize thermal energy utilization. The continuous operation mode is inherently more energy-efficient than discontinuous batch presses, substantially lowering energy cost per unit.
6. Outstanding Production Efficiency:
The continuous feeding and discharging mode eliminates the idle waiting time inherent in batch presses. This enables true, uninterrupted mass production, drastically increasing overall capacity and labor productivity.
This machine is widely used for producing:
Ultra-Thin Panels: 1-5mm Ultra-thin High-Density Fiberboard (HDF) and Particleboard, used for furniture backs, laminate flooring substrates, and decorative moldings.
High-End Decorative Panels: Substrates with high flatness for direct lamination with melamine-impregnated papers.
Standard Panels: Medium-Density Fiberboard (MDF), Particleboard, Oriented Strand Board (OSB).
Specialty Panels: Special materials requiring continuous pressing, such as fire-resistant boards and insulation boards.
