Continuous Flat Press Machine for MDF, 15000㎡/Year, PLC Control

This high-performance continuous flat press machine is optimized for MDF (Medium-Density Fiberboard) and HDF (High-Density Fiberboard) production. Equipped with Siemens PLC control, it ensures precise adjustment of pressure, temperature, and speed, improving board density uniformity and reducing waste.

Siemens' flagship PLC (simple logic controller) is designed for mid-to-high-end industrial automation scenarios. It has high performance, high automation and automation as its core advantages, and is suitable for complex applications such as intelligent manufacturing, process control, and motion control.

Among them, SIMATIC S7-1500 represents the current technical benchmark in the field of industrial control. Its open architecture and digital genes provide core support for the upgrade of Industry 4.0. For modern factories that pursue efficiency, reliability and intelligence, it is an ideal automation center solution.

Operating Principle: Continuous Flat Press  

1. Feeding  

Pre-formed continuous fiber mat (pre-pressed) enters the press via in-feed conveyor, typically equipped with metal detection systems to prevent mechanical damage.  

2. Nip Closure Zone  

- The mat progresses into a tapered wedge section with progressively reduced height.  

- Upper/lower steel belts (or heated platens) initiate closure, applying gradual compression (15-25% initial density increase) to expel entrapped air.  

3. Main Pressing Zone  

- Mat enters parallel sections under precisely controlled pressure (up to 6.9 MPa / 1,000 psi) via hydraulic cylinders.  

- Thermal energy transfer: Hot oil/steam circulates through platens (180-230°C), achieving:  

→ Lignin plasticization for fiber bonding  

→ Rapid curing of binders (UF/PF/MDI) within 90-120 seconds  

4. Thickness Calibration Zone  

- Laser-guided pressure profiling adjusts local compression to:  

 ✓ Compensate mat density variations (±1.5%)  

 ✓ Maintain thickness tolerance ≤±0.1mm (EN 319 compliance)  

- Critical for producing warp-free structural panels  

5. Pressure Release Zone  

- Controlled decompression over 1.5-2.5m length prevents:  

-Allow the internal stress of the sheet material to release slowly  

-Reduce the "springback" and deformation of the sheet materials

6. Discharge  

Cured continuous board exits for downstream processing:  

① Cooling tunnels (forced-air)  

② Cross-cut saws (±0.5mm length accuracy)  

③ Sanding lines (Ra ≤3.2μm surface finish)
