Process

Plywood is a wood-based panel product comprised of a collection of veneers that are glued together with a resin. To sum up the production process; logs are peeled into veneers, the veneers are lathered in glue, laid up so that the grain direction of each veneer is perpendicular to its adjacent veneer, pressed together, trimmed and sanded.

Step 1: Gather and Transportation of Raw Material

When trees achieve an ethical dimension of development, they are felled via prepared gatherers. Contingent upon the activity of the factory, vehicles like a standard procedure can be utilized to choose and fell trees employing satellite symbolism. Logs are transported from the forest concession to the mill to be processed. Transportation comes with its environmental issues in some instances, as forest areas are cleared to make room for roads and therefore new trees cannot grow.

Step 2: Sizing and Grading

Following stripping, the facade is moved along the creation line in long streams. They should be sliced to estimate and experience an underlying evaluating process. Evaluating is particularly vital concerning Birch Plywood, so most of the plants use filtering innovation to check for deformities in the facade, slicing to the required sizes and after that isolating potential face facade from the centre facade.

Step 3: Drying the Veneers

At this point, the veneers are still wet from being soaked in the log pond. The surfaces must be dried for a variety of reasons; from protecting the wood from fungal decay to increase the mechanical properties of the finished board.

Step 4: Repairing Defects

Once dry, veneers need to be repaired where defects exist. In the case of Birch Plywood, for example, open knots (where branches used to be) can be 'plugged' in. Splits in veneers on plywood can also be filled in, and mid-sized veneers can be finger-jointed together.

Step 5: Application of Glue and Lay-Up

Veneers are run through a glueing machine which essentially rolls the glue onto the face and back of the surface. They are then placed on top of an unglued surface so that the stack alternates; Glued, Unglued, Glued, Unglued and so on.

Step 6: Cold Pressing and Hot Pressing

Cold Pressing happens after the paste has been connected to set up the facade for Hot Pressing. This attempts to level out the facade and guarantee the dough is conveyed over the facade equitably. This part of the production process is where the actual panels begin to take shape. Multiple groups are loaded into the daylight press. The Daylight Press then compresses and maintains heated pressure on the boards for an extended period. This creates and maintains necessary contact between the glue and veneers. It also decreases tension in the glue line and the thickness of the glue layer.

Step 7: Trimming

Following Hot Pressing, the board is left to stabilise and cool down before further processing. Then it is a case of trimming down any excess veneer, so the board has square edges, then the boards are most commonly sanded using a large, industrial sander.

Step 8: Quality

The last item must be evaluated for quality; however, it wouldn't be proficient at holding up until the finish of the procedure to locate a massive issue with creation. Therefore, factories control their generation via completing various tests on various areas of the creation procedure, for example, testing dampness levels, formaldehyde discharge, toughness, and so forth.

Step 9: Packaging and Delivery

Finished products are then stacked up and banded together. Any relevant CE marks are printed on the packaging. We take delivery of plywood weekly, ready to despatch to you!
