Plywood Manufacturing Machinery

Plywood refers to that logs are spine into veneer by peeling machine , and then glued according to the veneer fiber direction which is arranged perpendicularly, and finally pressed into a wood-based panel. Plywood is the ideal product widely used in all kinds of furniture, office supplies, combination speaker, packaging exhibition and other industries. Main sections of plywood production line include peeling section, veneer drying section, gluing section, repress section, hot press section, saw edge section, sanding section...etc. The thickness range of plywood is generally the 8-18mm, board width is generally 915-1220mm. We can design and manufacture any size according to users' requirements.

Plywood Production Technology:

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%
Other machines
We can also provide other machines, just like veneer jointer machine, knife grinder and so on.

Complete plywood production line need the following 5 parts

Part 2; Veneer drying - veneer drying machine
Part 3 , Veneer handle : veneer composer ,veneer gluing machine , veneer assemble machine
Part 4 , Panel press , cold press + hot press
Part 5 ,Panel handle : sanding machine + dd trimming saw machine

(1) Automatic wood log cutting line
1) Full automatic cutting line
2) LEAD PLC and touch screen control system
3) Frequency adjustable cutting length and feeding speed.
4) Two way hydraulic wood clamping and cutting system.
The first step of veneer making from wood logs. cutting logs into pieces with required length automatically.Wood log from 6m cut into 4ft and 8ft size log.

(2) Log Debarker Machine
1) Heavy duty type
2) Huali Motor and Hardened Reducer.
3) Chrome hard treatment roller.
4) Wood chipper is optional
Chipper debarking machine, remove the bark from the tree logs and make log core round, meanwhile chips the barks.

(3) Veneer Peeling Machine

2) LEAD PLC control system with driver.
3) Servo motor feeding and cutting.
4) Huali motor and hardened reducer.
5) Free switching of 2 different cutting width.

Spindle veneer peeling machine suit big wood diameter, when your log more than 800mm ,suggest using this machine,usually no-card peeler main peeling cutting face veneer of plywood(0.2-0.5mm)

(4) Core Veneer Dryer
1) Easy operation with high efficiency and big yield.
2) Adopting advanced world famous brand electric components.
3) Adopts Finland and Italy design.
4) Automatic feeding device is optional.
Veneer drying machine is important machine in plywood processing, when you peeling get fresh veneer, for long stock ,need remove water and moisture,so you need core veneer dryer or drying line.
