OSB Production Line Making Machine Wood Veneer Rotary Machine
1) Log cutting:
Usually import log length is more than 6 meters. Cutting according
to the technology required length and quality. The cutting length
should be product length add remains. For example, product is
1220mm*2440mm, cutting length usually be 2600mm or 1300mm. log
length, camber and demerit affect plywood output directly. Remains
are small wood pieces, truncations, sawdust, tec. Log cutting
wastage ratio is 3%-10%.
2)Veneer peeling:
Peeling is the most popular plywood producing process. Back veneer
thickness is about 0.6mm, core veneer and centre veneer thickness
is about 1.8mm.
3) Drying:
Veneer is moist. it should be dried according to the technology
requirement. After drying, it will shrink. Dimension will become
smaller. Veneer length, width, thicknesswill shrink. Shrink wastage
is related to wood material, moisture containing, veneer thickness.
Shrink wastage is 4%-10%.
4) Veneer gluing and handling:
Handling include cutting, putting veneer together and mending. Cut
zonal veneer into specification veneer or proper size which can be
put together. Narrow zonal veneer can be put together into one
veneer. Veneer with demerit can be mended to be qualified. Wastage
in this part related to log material, peeled veneer quality, dried
quality, and worker operation skill. Wastage ratio is 4%-16%.
Import veneer processing plywood wastage ratio is 2%-11%.
5) Cold and Hot press:
Veneer be glued and stacked, then glue together under set
temperature and pressure by hot press. As veneer temperature and
moisture containing changes, veneer will shrink. Shrink wastage is
related to temperature, pressure, hot press time, wood material,
moisture containing,wastage ratio is 3%-8%
6) Edge trimming:
Trimming the edge of the plywood flank from hot press to qualified
plywood board. Remains related to process remains and product
dimension. Production is bigger, wastage is smaller.Wastage ratio
is 6%-9%
7) Sanding:
Sanding plywood surface to make it good. Wastage is powder. Veneer
quality is good, sanding is less. Wastage ratio is 2%-6%
