The core principle of the continuous laminating press is to pass the material between two high-strength steel belts that circulate around a system of special rollers. The steel belts press the material against a series of meticulously arranged internal heating platens and pressure elements, completing the hot pressing process during continuous linear movement.
The workflow can be simplified as follows:
1. Feeding: Raw material (e.g., fibers, powder, prepreg, veneers) is fed into the steel belt system via a conveyor.
2. Pre-pressing & Heating: The material enters the press inlet, is gripped by the upper and lower steel belts, begins to contact the heating platens, and its temperature gradually rises.
3. Main Hot Press Zone: The material, driven by the steel belts, passes through the pressure zone composed of multiple hydraulic cylinders or pressure rollers. In this zone, the material is simultaneously subjected to uniform heat and precise pressure, undergoing physical and chemical changes such as curing, polymerization, bonding, or density increase.
4. Pressure Profile Control: By programming the pressure applied by elements in different zones, specific pressure profiles can be achieved (e.g., high pressure at the inlet, constant pressure in the middle, lower pressure at the outlet) to accommodate the rheological properties of different materials.
5. Cooling & Setting: In some designs, a cooling zone may be included at the press outlet to allow the product to cool and set under pressure, preventing deformation.
6. Continuous Discharge: The finished product is continuously discharged from the other end of the press and can be directly cut to length or coiled.
1. Steel Belt System:
Two high-temperature resistant, high-strength alloy steel belts act as the carriers in direct contact with and transporting the material.
Requires extremely high surface finish to ensure product surface quality.
Equipped with tensioning and tracking (edge control) systems to ensure stable operation without deviation.
2. Heating System:
Typically consists of multiple independent heating platens (using steam, thermal oil, or electricity).
Allows for zonal temperature control, creating required temperature gradients to meet the material's temperature needs at different curing stages.
3. Pressure Generation System:
Hydraulic Cylinder + Pressure Pad System: Multiple hydraulic cylinders push against pressure pads located behind the heating platens, transferring pressure through the platens and steel belts onto the material. This is the most common type.
Pressure Roller System: A large number of densely arranged pressure rollers are installed within the frame, applying pressure by adjusting the height of the rollers.
4. Frame & Drive System:
A robust frame to withstand enormous pressure.
Drive rollers that move the steel belts continuously, usually powered by variable frequency motors for stepless speed control.
5. Control System:
The core consists of a PLC and HMI.
Allows precise setting and control of all process parameters (temperature, pressure, speed, thickness) and stores numerous recipes.
Parameter | Typical Range / Description |
Max. Pressing Force | Customizable based on process (e.g., 100 - 10,000 Tons) |
Platen Size (Width x Length) | Width: 1.2m - 3m+; Length: Custom per production line design |
Heating Method | Electric, Thermal Oil, Steam Heating |
Max. Working Temperature | 200°C - 300°C (or higher) |
Thickness Control Accuracy | ±0.05 mm - ±0.15 mm |
Control Core | PLC + Touchscreen, supports remote monitoring |
Very High Production Efficiency: Eliminates the idle time of intermittent presses, enabling 24/7 non-stop production. Output capacity far exceeds that of similarly sized intermittent presses.
Superior Product Quality:
Uniform Thickness: The continuous pressing process ensures excellent thickness consistency both longitudinally and transversely.
Stable Performance: Stable thermal conditions and precise pressure control result in very uniform physical properties (e.g., density, internal bond strength).
Significant Energy Savings:
High thermal efficiency as continuous operation leads to less heat loss compared to frequently opening/closing intermittent presses.
If equipped with a Servo Hydraulic System, energy savings are even more dramatic, achieving "pressure on demand."
High Degree of Automation: Easily integrated with upstream and downstream equipment (e.g., forming stations, coolers, saws) to form fully automated production lines, reducing labor dependency.
Wide Raw Material Adaptability: Can produce products of different thicknesses, densities, and specifications by adjusting process parameters.
The continuous laminating press is a key piece of equipment for achieving high efficiency and quality production in the following industries:
Wood-Based Panel Industry: The most classic application.
Production of MDF (Medium Density Fiberboard), HDF (High Density Fiberboard), Particleboard, OSB (Oriented Strand Board).
High-End Composite Material Molding:
Continuous pressing of Carbon Fiber Composites and Fiberglass (GRP).
Continuous production of SMC/BMC molded parts.
Manufacturing of GMT (Glass Mat Thermoplastics), LFT (Long Fiber Thermoplastics) sheets.
Rubber Industry: Continuous vulcanization of conveyor belts, rubber sheets, and floor mats.
Building & Decorative Materials: Continuous lamination of HPL (High-Pressure Laminates), metal decorative panels, and wood-plastic composite panels.
Others: Such as insulation boards, packaging materials, and the reinforcement treatment of specialty papers.
