What is MDF?

Multi-layer MDF 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.

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.

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.

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.

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.

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.
10. Heating energy center
Supply heating for the process of drying ,hot press, glue making section .Caloric value can customized design from 12-60MW.
Capacity | 30000-150000cbm/year |
