PRODUCTION PROCESS
Step 01: Classify veneer
Grade A+ peeled board : A board of sufficient size, sufficient and uniform thickness, surface without defects, flat and smooth, bright wood quality; This type of peeled board is often used as the surface layer of plywood panels.
Type A peeled board: A board of sufficient size, sufficient and uniform thickness, no surface defects, few wood knots, small size;
Step 2: Grind the veneer
The edge grinding machine grinds both sides at the same time along the line, can cut veneer with torn edges into straight lines, completely solving the quality defects of plywood. The machine can automatically sand edges and has a dust extraction device.
Step 3: glue
Veneers will be glued and stacked in 2 directions to ensure the boards have good strength in both directions and prevent shrinkage. In particular, some types of plywood with special requirements will have layers in many different dimensions.
Step 04: arrange plywood and conveyor belt.
The process of layering panels is very important in the process of manufacturing film-coated plywood. To create a tight fit of the panels and increase durability, the layers of panels need to be tightly packed together, without creating gaps.
Step 5: cold pressing.
After the layers are arranged together to a sufficient thickness, they will be put through an 800T cold press to shape.
Step 6: sand and repair the board surface
After cold pressing, the board will be sanded and repaired to completely fix the nicks on the board's surface.
Step 07: 1st hot pressing
1600T hot press, the hot press will press the plywood at a temperature of 110-150 degrees Celsius for 2-5 minutes, then the press opens and the plywood switches to the cold stage after hot pressing.
Step 8: prime the plywood surface
Patches missed surface defects and shrinkage. Discard products that have peeling surfaces or do not meet the requirements. Trim the exposed board edges later. Cut the saw and fix the frayed board edges (if any).
Step 9: Sand twice
Sanding on both sides creates a flat surface for the plywood. After sanding, depending on requirements, the plywood can be primed with a flat layer of UV paint before being coated with film.
Step 10: Cut edges
Eye necklaces are precisely cut with square edges and standard sizes.
Step 11: apply film
Vật liệu phủ mặt cho ván ép thì rất đa dạng, có thể dùng Melamin, Laminate, VeneSurface coating materials for plywood are very diverse, you can use Melamine, Laminate, Veneer or UV coating according to customer needs.
Step 12: 2nd hot pressing
This hot pressing takes only 2-3 minutes because the purpose is for the film to adhere tightly to the surface of the board
Step 13: Product inspection (QC)
Any panels with even minor defects will be rejected.
