Product Detail

Medium density fiberboard (MDF) is a kind of artificial board made from wood fiber or other plant fiber as raw material, through fiber preparation, sizing, waxing, drying, forming, hot pressing, sawing and sanding.Its products are widely used in furniture manufacturing, construction, interior decoration, interior decoration of vehicles, ships and housing of household appliances and other industries.

1.   CHIP PREPARATION SECTION

Timber, wood branches and wood residues are cut into chips of certain size. Chips from chip silo will be screened to remove fines, soil and stones.

2. FIBER MANUFACTURING SECTION

Wood-chip out-feeding from pre-heat silo, entering digester vessel via plug-screw feeder to cook and soften the wood-chips, the cooked wood chip is reduced into fiber by the function of heat and mechanical movement Then the wet fiber is conveyed by high-speed & high wind via cyclone & rotary discharge fall to the forward-backward belt conveyor, then sent to the forming metering silo.

3. GLUE REGULATING AND APPLYING SECTION

Our technique is glue applying before drying. Melt paraffin is sent to the de-fiber, mixed evenly with the fiber. The glue mist adheres to the surface of fiber by high speed wind-flow in the drying pipe.

4. MAT-FORMING AND HOT-PRESSING SECTION

Dry fiber is sent into the metering silo by wind-conveying system, spread evenly onto annular screen-belt conveyor by spread rollers. There is vacuum box under the screen-belt, air is sucked through the screen-belt and fiber is adhered on the screen-belt, thus forming a loose mat Pressed by the pre-press, the loose mat is changed into a relatively density mat, then cut into sized mat by mat-transversal-longitudinal saw. The mat is transported and carried to board loader. The caul-less belt-tray of loader transports the mat to hot press, meanwhile, the pressed rough board is pushed out on the un-loader. Under the function of high-pressure and high temperature. The un-loader discharges the board one by one.

5. FINISHED HANDLING/ SANDING 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.
