Technical Specifications
Parameter | Value |
Max Pressure | 10 MPa |
Heating System | Thermal Oil Circulation |
Control System | Siemens PLC + Touchscreen |
Board Thickness | 2-40mm |
Power Supply | 380V/50Hz |
Hot press plate system: Composed of multiple heating plates, the interior is heated by heat transfer oil or steam to provide uniform temperature.
Steel belt system: Two circulating steel belts (upper and lower) hold the slabs and run continuously to ensure uniform pressure transmission.
Hydraulic system: Pressure is applied through hydraulic cylinders, and the pressing force in different areas can be adjusted in sections.
Control system: PLC or computer control, real-time monitoring of parameters such as temperature, pressure and speed.
Auxiliary equipment: includes paving machines, pre-pressing machines, cooling sections, sawing systems, etc.

Independent Zone Control | Each pressure zone's cylinder group can be independently set and precisely controlled to exert a specific pressure (pressure, unit usually MPa or Bar). |
Pressure Profile Programming | Operators can program a pressure profile along the press length based on different products (thickness, density, raw material) and process requirements. For example: Infeed Section: High pressure (rapidly compresses the mat, expels air, establishes initial contact). Middle Section: Pressure can be reduced (to avoid over-pressing) or maintained (to sustain curing conditions) based on resin cure kinetics. Outfeed Section: Pressure gradually reduced to near zero (allows the panel to cool and set without pressure, minimizing springback and internal stress). Dynamic Adjustment: The control system constantly monitors pressure in each zone and makes micro-adjustments based on thickness feedback and raw material variations (closed-loop thickness control). Width-Wise Pressure Equalization: Within each zone, the control system strives to ensure uniform pressure distribution across the width to avoid defects like "washboarding." |
Independent Zone Temperature Control | The heating plates are also divided into multiple temperature zones along the press length (usually corresponding to or slightly different from pressure zones). Each zone has independent flow control valves for thermal oil (or steam). |
Temperature Profile Programming | Operators can program a temperature profile along the press length. For example: Infeed Section: Higher temperature (rapidly heats the mat surface, initiating resin cure). Middle Section: Maintained high temperature (ensures complete core layer curing). Outfeed Section: Temperature gradually reduced (begins cooling the panel, stabilizes dimensions, reduces blister risk from steam release). Adaptation to Different Resins: Different adhesives (Urea-Formaldehyde UF, Melamine-Urea MUF, Phenol-Formaldehyde PF, Isocyanate MDI, etc.) have different optimal cure temperature ranges, requiring corresponding adjustments to the temperature profile. |
Line Speed Control | Precisely sets the line speed (unit usually meters/minute) of the mat through the press by controlling the drive motor speed via frequency converters. |
Determines Pressing Time | Speed directly affects the total time the mat is subjected to heat and pressure within the press (Pressing Time = Effective Press Length / Line Speed). |
Synchronization with Pressure/Temperature | Speed must be coordinated with the set pressure and temperature profiles. Producing thick panels requires longer pressing times (i.e., slower speeds), while thin panels can use faster speeds. Speed changes affect the actual duration of pressure and temperature exposure within each zone for the mat. |
Impacts Production Capacity | Speed is a key factor determining the production line's output capacity. |
1.Size & Dimension Customization:
Working Width | Customized based on target product specifications and capacity requirements (common widths: 8ft/2440mm, 9ft/2745mm, wider). |
Press Length | Customized based on target product thickness range, required pressing time, and capacity needs (longer presses allow longer pressing times for thicker panels or higher capacity for thin panels). |
Maximum Opening | Determines the maximum mat thickness that can be processed. |
Maximum Working Pressure | Determined by target product density and process requirements. |
2.Performance Parameter Customization:
Number of Pressure Zones | More zones allow finer pressure profiles and greater flexibility . |
Number of Temperature Zones | The more zones there are, the more flexible the control will be. |
Maximum Working Temperature | Determined by the type of adhesive used (e.g., MDI requires higher temperatures). |
Cylinder Size & Layout | Affects pressure distribution uniformity and response speed. |
Steel Belt Specifications | Thickness, material, surface treatment (e.g., coating) selected based on process requirements. |
3.Control System Customization:
Control System Brand & Grade | Offering different tiers of control systems (e.g., Siemens, Rockwell). |
HMI Interface & Functionality | Customizing operator interfaces, integrating specific features like recipe management, data analytics, remote diagnostics. |
Interfaces & Communication | Meeting requirements for integration with the customer's existing DCS/MES systems. |
4.Material & Process Package Customization:
Heating Plate Material & Channel Design | Optimizing heat transfer efficiency and temperature uniformity. |
Hydraulic System Configuration | Selecting pump and valve brands/specifications meeting response speed and precision requirements. |
Lubrication System Type | Different lubricants and spray methods. |
Accompanying Process Package | Providing a basic process parameter database (recommended pressure/temperature/speed profiles) tailored to specific raw materials (wood species, fiber morphology) and specific products (standard MDF, fire-retardant board, moisture-resistant board, ultra-thin board, thick board) as a starting point for commissioning and production. |
