Melamine plywood production process

The melamine plywood production process includes the following main steps:

Melamine Plywood Production Process

1 Selecting the core veneer

Telling about melamine plywood for furniture applications, we inspect 100% piece by piece and mainly utilize the core veneer grade A made by Acacia, Eucalyptus. mixed hardwood,...The veneers that do not meet the requirements will be rejected. In case the customers would like a cheaper price & suitable to the quality they request, some core veneer grade B is used for production with grade A.

• A grade: Flat, good surface, no holes, fully 4 edges, no defect.
• B grade: flat, good surface, 1-3 small holes, fully 4 edges 

Selecting the core veneer

2. Sanding the edge

A grade core veneer will be sanded on both short edges in order that when it is laid up together, the plywood is not overlapped too much, resulting in the evenness in thickness.

Sanding the edge

3. Gluing the core veneer

The glue used for manufacturing the birch plywood is glue E0 carb P2. It will be mixed with flour and some colors, which creates a complete liquid with high adhesive.

In the production of birch plywood, the veneer is also passed through a glue machine one by one so that the glue is evenly adhered on both sides of the veneer and it is fully coated with glue. Peeled boards that are not evenly glued will lead to delamination and edge separation if put into production.

4. Arranging the core veneer

The sheets are arranged in lines, one wet layer and then one dry layer to create a strong connection among them. The outer layer will use all white A grade veneer and If B grade veneer is used, it will be patched carefully by the workers.

The edge-sanded sheets put along the line will be fixed with plastic staplers

5. Cold - pressing the core

 After laying up the veneer, The arranged veneer sheets will be put into the cold press machine, with at least 4 pistons & high pressure to form the shape for about 4- 8 hours depending on the weather condition, which helps the panels shape temporarily and solidify the structure inside.

6. Repairing the core

 Before hot pressing, workers will use expert techniques to turn over the board and remove the excess wood at the edges and veneer overlap on the surface.

Our worker will cut and reject the excess veneer, and cover the gap of veneer if necessary. The core must be full, flat afterwards

7. Cutting

After cold pressing, the core will be cut for the first time,  removing the excess edge.

8. Hot pressing the core

The core sheet will be put into the hot press machine, one tray for one sheet,  ensuring flat boards and quite accurate thickness. 

The hot-pressing time depends on every thickness & the weather condition for about 20 to 50 minutes. for example 25 minutes with 15mm, 40 minutes with 20mm,…

The high pressure and suitable temperature is set up by our experienced workers, which helps bond the veneer layers together and permanently solidify the product

9. Puttying and sanding the surface (1st time)

• Workers will use putty powder to put in all the tiny gaps on the surface of the core then the sheets will be naturally dried up in 3-4 days, when the putty is fully dried up, the sheets will be sanded carefully.
• Both sides of the sheet will be sanded with the aim to break the rough surface

10. Puttying and sanding the surface (2nd time)

• Workers will use putty powder again to put in all the tiny gaps on the surface of the core.
• After the sheet is dried up, it will be sanded for the second time by another machine. This machine is used to make the surface completely smooth before we put the birch face in

11. Gluing the core

After the 2nd surface puttying and sanding, the sheet is coated with anti-core exposure glue in order to make the product look good.

12. Check the surface of the core

The core will be checked again, any tiny holes or defects will be fixed before processing next step

13. Gluing and pasting the face

After the core is checked, it will be coated with glue in order to put the face veneer. The glue used is the same as the glue we used to bond the core. The faces are carefully put on the glue coated core.

14. Hot-pressing the face

The sheet will be hot pressed in about 6-7 minutes, at temperature about 110-120 degrees, with high pressure of 110-120 kg/m3 because this step aims to stick the face veneer on the board.

15. Cutting to size

The panels will be cut into the standard size as per customer's request. The popular sizes of commercial plywood are 1220x2440mm,….

16 Repairing the face

After cutting, our workers inspect the face of the sheet, if it is swollen, or missing or torn, they will repair it by using the glue

17. Sanding the surface

The sheet is sanded for a beautiful and smooth surface. This step makes the sheet look a little shiny.

18. Inspection

Before being delivered to our dearest customers , every plywood sheet will be thoroughly inspected 1 by 1 by our experienced and highly skilled QC team to minimize the risk of receiving defective goods for the buyer. Our workers carefully check the dimensions, thickness, moisture content , face and back, edge, ,strength …of each piece. Besides, for the 11mm up thickness, the QC team also used a wooden hammer to knock on several points of the sheet and listen to the sound to inspect the structure and inside delamination.

Our TTP is confident of being one of the only units, which has a 100% birch plywood piece by piece inspection process before stuffing from professional and highly experienced QC teams with the aim of bringing the best Vietnamese plywood products and value to customers.

19. Packaging

Finally, we count and tie up pieces to create a bundle. Four corners of bundles are covered with cartons, tied with strong steel straps, put on the high pallet to make the base which protects the product during the shipping process by sea.

Packaging

20. Loading

These packages will be stored in a spacious and dry warehouse and ready to be loaded into containers for delivery to customers.
