The whole production line mainly includes: Chipping machine, Screen, Defibrator, Dryer, Forming machine, Pressing machine, Cooling. Sanding machine, Cutting machine.
Each machine can be different specification according to different production capacity and other factors.
1. Raw Material Preparation Section:
The first step in MDF-HDF production is the preparation of raw mateials. Hardwood or softwood logs are debarked and chipped into small pieces. These wood chips are then screened to remove impurities and sorted based on their size and moisture content.
2. Drying Section:
The moisture content of the wood fibers is reduces through a drying process. This is crucial to ensure the stability and dimensional accurancy of the MDF/HDF panels. The fibers are typically dried in large rotary dryers or using a hot air drying system.
3. Defibrator Section:
The wood chips cut by the chipper are preheated and cooked, separated machanically, and the fibers are obtained. This step is directly related to the quality of the final density board. The defibratoe mainly includes chip preheating bin, cork screw, cooking vat, electronic control system, lubrication system.
4. Blending and Resin Application Section:
The dried wood fibers are blended with resin binders and other additives. The resin binder, commonly urea-formaldehyde, helps to bind the fibers together during the pressing stage. Other additives, such as paraffin wax, may be added to enhance water resistance and improve the board's surface quality.
5. Forming and Pre Pressing Section:
The blended fibers are spread evenly onto a forming line, where they are formed into a mat. The mat is then tranfered into a hydraulic press, where it undergoes a high-pressure and high-temperature process. This process comresses the fibers and activates the resin binder, resulting in the formation of a solid, dense board.
6. Trimming and Sanding Section:
The panels will be the next step, to achieve the desired thickness, smoothness, and surface finish. Trimming machine for trimming and cutting mdf/hdf edges, making its edge be clean and tidiness, and each one is same size. Sanding machine for calibrating mdf/hdf thickness, making its thickness be accurate and balance, and polishing its surface, make its surface be smooth.
