Plywood, the Most Advanced Wood Based Panel
Plywood has played a crucial role in shaping the modern world for over a century, being used in various industries such as cars, airplanes, furniture, architecture, and manufacturing processes from manual to automated. Plywood has become one of the most frequently used materials in the digital era as well.
Plywood is a substance made up of thin layers or plies of wood veneer that are bonded together, with each layer having its wood grain turned up to 90 degrees from the one next to it. The plywood's strength, durability, and stability are due to its alternating perpendicular layers.
We are the leading supplier of plywood projects for mills worldwide. Any kind of wood, softwood or hardwood, can be turned into plywood using our equipment. Customers all throughout the world depend on our equipment and methods to guarantee that they are producing the precise plywood that they need.
Veneer And Plywood Production Process
1. Log Grading:
The quality and suitability of the logs for veneer-making are determined by examination and classification.
2. Log Conditioning:
Logs can be prepared for peeling by undergoing conditioning methods like soaking or steaming to increase their flexibility.
3. Debarking and Cutting:
The logs have their outer bark removed before being cut into appropriate lengths for additional processing.
4. Veneer Peeling:
The logs go through a veneer peeling machine where they are turned against a blade to create long sheets of veneer.
5. Green Veneer Grading:
Following their peeling, the veneer sheets are inspected and categorized based on their quality, thickness, and surface flaws.
6. Clipping:
To enhance the quality and appearance, any flawed parts of the veneer sheets are cut or trimmed.
7. Green Veneer Composing:
Before the drying process begins, the graded veneer sheets are sorted and stacked together into heaps.
8. Veneer Drying:
In order to lower the moisture content of the veneer stacks, they are put in a veneer drier and precisely dried.
9. Dry Veneer Grading:
The veneer sheets are inspected and categorized based on their quality, moisture content, and other requirements once they have dried.
10. Veneer Patching:
Flaws or blemishes found in the dry veneer sheets are fixed or mended with appropriate materials.
11. Core Veneer Composing:
The graded and patched veneer sheets are organized and grouped together in stacks to create the central layer of the plywood.
12. Face Veneer Composing:
Plywood's surface layers are formed by stacking and organizing graded and patched veneer sheets in a similar manner.
13. Veneer Scarf-jointing:
Veneer sheets can be scarf-jointed, joining two or more sheets to make larger veneer pieces.
14. Gluing:
Adhesive is used on the veneer sheets to adhere them together, creating the plywood panel.
15. Layup:
The veneer layers are stacked with their grain orientations alternating to increase the stability and strength of the plywood.
16. Pre-pressing:
To remove excess moisture and guarantee that the adhesive is distributed uniformly, the stacked veneer sheets are put in a pre-press.
17. Hot Pressing:
Pre-pressed veneer is stacked and placed in a hot press, which employs pressure and heat to activate the adhesive and form a robust plywood panel.
18. Panel Repairing:
Following the process of hot pressing, any flaws or blemishes found in the plywood panel are fixed or filled to enhance its overall quality.
19. Panel Trimming:
With saws or other cutting equipment, the plywood panel is cut to the necessary dimensions.
20. Panel Sanding:
Sanding is done on the trimmed plywood panel to achieve a smooth and consistent surface.
21. Panel Over-laying:
Extra layers or veneers can be applied to the plywood panel to improve its look or characteristics.
22. Panel Trimming
The plywood panel with overlay is cut once more to reach the desired final size.
23. Panel Edge-painting:
Painting the margins of the plywood panel lowers the possibility that moisture will cause damage to it, as these are the areas where the panel is most vulnerable.
24. Panel Packing:
The completed plywood panels are arranged, covered, and prepared for storage, shipping, or delivery.
