MDF Production Line Press Machine/HDF Machine Supplier

Product Description

What is MDF/HDF?
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibers, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibers, but can be used as a building material similar in application to plywood. It is stronger and much denser than particle board. The name derives from the distinction in densities of fibreboard. Large-scale production of MDF began in the 1980s, in both North America and Europe.
What is MDF/HDF production line?
MDF/HDF is a kind of excellent substitute for natural wood panel with wide application. Materials such as wood and other plant fiber after being added suitable urea formaldehyde resin or other adhesives forms 450-880 kg/m3 panels on hot press. The panels are characterized with tight and smooth surface, uniform core layer and good wood working performance.
The line consists of chip preparation, fiber preparation, glue mixing and applying, mat-forming and hot-pressing, cooling and sizing, sanding.

1. Chip prepare section
Drum chipper is our conventional product widely used in the industrial production of paper, MDF and PB, etc. Raw materials are primarily small diameter logs, logging residues such as branches and twigs as well as wood-processing leftovers like planks, slabs, cores and veneer wastes, etc.. Our company can also supply a complete set of equipment for chip preparation section. The chipper mainly consists of machine base, knife rotor, upper and lower feeding rollers, hydraulic system and electrical control system.

2. Fiber prepare section
Chips are transported to upper bin of refiner and positively fed to digester by screw feeder for steaming. Steamed chips will be isintegrated to fiber under the force of heat and mechanism. Mix drying medium and wet fiber which is in the state of suspension with the help of high pressure air flow, and thus exhaust moisture in fiber via drying medium to get dry fiber. Dry fiber falls on belt conveyor through cyclone discharge valve, and then be transported to dry fiber bin for storage.

3. Glue dosing system

Process of glue applying before drying is adopted. Feed molten paraffin and water-proof additive to refiner. Paraffin is mixed with fiber uniformly under the force of refiner plates. Glue is transported to the blow line of fiber discharge valve. This section can be controlled by PLC or computer.

4. Dryer section

The fibers after mixing with glue is transported to drying ducts along with steam, and transported to cylcone separator by hot air. And thus the water in the fibers is drained out with hot air. The dried fibers and air is separated and then transported to silo.

5. Forming section

Fluffy mats will be pressed by pre-press. Pressed mats are cut into definite length by longitudinal and transversal saw, then transported to loader passing through accelerating conveyor, storage conveyor and extension conveyor. When finishing loading mats, carriage in the loader will feed conveying belt and mats into hot press, at the same time, shovel head at the front end of conveying belt pushes out pressed board.

6. Pre-press section

When carriage comes to terminal, boards have been into unloader, and mats also arrives to due position. Carriage returns, conveying belt turns forward. Mats are in the relative still state and stay on the platen of press when velocity of conveying belt is the same as the returning speed of carriage.

7. Hot press section
Glue in the mats cures, thanks to temperature and pressure in hot press, and hence boards with definite intensity and thickness form. Rough boards will be put on support via unloader. Outfeeding conveyor will unload boards one after another to next section when cage comes down.

8. Cutting section

After hot press machine , the boards to the cutting machine , 4x8ft,6x9ft,6x12ft all can design depends on customer requirement.

9.Cooling section

Rough boards after air cooling are turned into cut-to-size boards via longitudinal and transversal saw. And then cut-to-size boards are sanded, sorted, stacked and packed for storage.

10. Sanding section
The board are sanded, checked and stored. And need 2sets sanding machine, one is 2-head sanding machine; another one is 4-head sanding machine. And sanding machine brand is Sufoma, which is best quality in China.
