Ⅳ. Multi-Opening Hot Press
The particleboard multi-opening hot press is an industrial equipment that compresses wood particles and adhesives into panels under high temperature and pressure. Its core feature is a vertically stacked multi-layer heated platen structure, enabling simultaneous pressing of multiple mat stacks to significantly enhance production efficiency.
Core Structure and Components
1. Frame System
High-strength steel frame supports multiple platens, withstanding system pressure up to 3,000 tons.
Columns (diameter 300–500mm) ensure structural stability under extreme conditions.
2. Heated Platens
8–20 stainless steel platens (thickness 80–120mm) per unit, with hydraulically adjustable spacing.
Steam channels (150–220°C) or electric heating systems maintain temperature precision within ±2°C.
3. Hydraulic System
High-pressure oil pumps (25–35MPa) drive synchronized cylinders to achieve uniform pressure (0.5–2.5MPa).
Proportional valves precisely control pressure curves (ramping-holding-decompression), with cycles adjustable from 15–45 minutes.
4. Control System
PLC integrates closed-loop control of temperature, pressure, and time, monitoring each platen in real-time.
HMI interface stores process parameters (e.g., temperature profiles, pressure gradients, curing times).
Technical Advantages
High Efficiency: 20-opening press produces 19 standard panels (1220×2440mm) per cycle, exceeding 1,000m³ daily output.
Quality Control: Interlayer pressure compensation ensures thickness consistency (±0.2mm tolerance).
Energy Saving: Waste heat recovery cuts steam consumption by 30% (energy use ≤120kWh/ton).
Applications
High-Density Boards: ≥800kg/m³ load-bearing furniture components
Fire-Rated Panels: B1-class building partitions with flame retardants
Moisture-Resistant Boards: MF resin-treated substrates for bathroom cabinets
