Plywood production process

Veneer finishing → gluing → assembly → pre-pressing → hot pressing → sanding → laminating → secondary hot pressing → trimming → packing and storage.


Block board production process:

Thin wood bar → splicing on glued panel → pre-pressing → hot pressing → sanding → laminating → secondary hot pressing → trimming → packing and storage.


Veneer finishing:

Veneer finishing includes cutting, puzzles and repairs. Cut the dry strip veneer and zero class veneer into standard veneer and splicable veneer. The narrow veneer is spliced into a whole veneer. The defective whole veneer can be repaired to achieve the quality of the process Claim.


Gluing:

The classified veneer is glued by a glue applicator, and the melamine waterproof glue is mixed with flour at an appropriate ratio, and red powder is added to distinguish it, so that the face is evenly and appropriately glued.


Group billet:

Put the glued veneer on the case and spread it to the size and specifications required by the customer, and use the complementary split layer method for splicing and repair to make the multilayer plywood structure stronger.


Cold pressing:

The preformed plywood is cold-pressed once, and then put into a pre-press for a certain amount of time to pre-press.


Hot pressing:

The pre-pressed slabs of the rubberized assembly blank are hot-pressed on a hot press at a certain temperature and pressure for a proper time to make the multilayer plywood firmly bonded.


Sanding:

The surface of the hot-pressed plywood is sanded by a sander to make the surface smooth and beautiful, so as to facilitate the film forming.


Lamination:

The sanded plywood is covered on both sides with a peach core film or waterproof black film paper for building templates for secondary hot pressing


Trim:

The hot-pressed wool board is cut into the specifications required by the customer on a sawing machine.
