Plywood, a premium “green” material, is increasingly favored as a superior alternative across various industries. Known for its resistance to warping, moisture resistance, and eco-friendly properties, plywood is widely used in interior design and construction. Producing high-quality plywood involves a complex, multi-step process. In this article, let’s take an in-depth look at the plywood manufacturing process at ADX Plywood.

Plywood Manufacturing Process at ADX
Plywood, also known as veneer board or laminated wood, is an engineered wood product composed of multiple thin layers of wood veneer bonded together using specialized adhesives. The market offers various types of plywood with different surface finishes and core structures to meet diverse user demands. At ADX, we specialize in three primary types of plywood: veneer plywood, melamine plywood, and film-faced plywood.
ADX Plywood is one of the top plywood manufacturers in Vietnam, operates a state-of-the-art manufacturing facility in Quang Binh, supported by nearly 28,000 hectares of licensed plantation forests. The production process at ADX follows strict technical stages, ensuring consistent quality.
Step 1: Harvesting raw logs
The primary raw materials for ADX plywood include acacia, eucalyptus, and rubberwood, selectively harvested from our plantation forests. Logs with a diameter of at least 12 cm are felled and cut into standard-sized sections to prepare them for further processing.
Step 2: Debarking and veneer peeling
Once harvested, the logs undergo initial preprocessing, where the outer bark is removed before being fed into specialized veneer peeling machines. These machines slice the logs into thin wood sheets with a uniform thickness of approximately 1.7mm. ADX employs a rotary peeling technique, which ensures maximum material utilization, peeling from the outer layer inward until the entire log is used.
The cutting machinery used in this stage is equipped with ultra-sharp blades to ensure consistent veneer thickness and prevent any defects or irregular cuts.
Step 3: Veneer sorting and drying
After peeling, the veneer sheets are categorized based on wood type and dimensions. Defective sheets that do not meet quality standards are discarded. The selected veneer is initially air-dried to reduce moisture content to around 20%-30% before being stacked and transferred to the Rulo drying chambers.
Under strictly controlled temperatures, the veneer is dried to achieve the required moisture content. Once dried, the veneer sheets are graded based on surface quality into A, B, C, D, and F grades, where A represents the highest quality with minimal defects.
Step 4: Veneer stitching and glue application
To create larger plywood panels, the veneer sheets are stitched together using synthetic resin thread. This process ensures no impurities are introduced into the wood and allows the resin thread to melt during the subsequent hot pressing stage.
The stitched veneer panels are then passed through a roller gluing machine to apply adhesive evenly and efficiently. ADX exclusively uses E0-grade adhesive, which meets strict formaldehyde emission standards (near-zero emissions), ensuring health safety for both workers and end users.
Step 5: Veneer layering
This step is crucial, determining 90% of the final plywood quality. The glued veneer sheets are stacked according to the required thickness and number of layers, forming a continuous production line. The layers are held together using plastic dowels at key junctions to maintain stability.
At the end of the lay-up line, the assembled sheets are trimmed using precision cutting machines to ensure standardized dimensions. The layering technique impacts plywood performance, and ADX manufactures three primary plywood configurations:
- LVL (Laminated Veneer Lumber) – Alternating grain directions for high strength
- LVD (Laminated Veneer Directional) – All veneers aligned in the same direction
- LVB (Laminated Veneer Balanced) – Randomized veneer layering for uniform properties
Step 6: Cold pressing & Hot pressing (Core Bonding Process)
The stacked plywood sheets undergo cold pressing to ensure uniform adhesion and flattening. This serves as the initial stage in shaping the plywood panel.
After cold pressing, the plywood core is inspected and repaired, where excess material is trimmed, and any gaps are filled. The sheets are then hot-pressed under high pressure to solidify the adhesive and create a strong bond between the veneer layers.
Unlike cold pressing, which processes full plywood stacks, hot pressing treats each panel individually, applying controlled heat and pressure to meet specific moisture and flatness requirements. ADX adheres to strict moisture content guidelines, maintaining:
- Below 12% moisture for standard plywood
- Below 8% moisture for film-faced plywood
Step 7: Surface repair & finishing
After hot pressing, the panels undergo a secondary inspection and surface treatment, ensuring a smooth, defect-free finish.
Step 8: Sanding & Initial trimming
The plywood panels are processed through automated sanding machines to achieve a smooth surface on both sides. Specialized lifting devices flip the panels automatically for uniform sanding. The panels are then pre-cut to prepare them for final sizing.
Step 9: Core sealing & Surface lamination
To enhance surface aesthetics and durability, the plywood core is treated with a sealing coat to prevent visible wood defects (e.g., knots, joints) from showing through thin surface layers. The panels are then passed through adhesive rollers and laminated with the selected surface finish.
ADX provides three primary surface options:
- Veneer Plywood – Features a natural wood veneer layer
- Melamine Plywood – A resin-infused paper layer offering water and scratch resistance
- Film-Faced Plywood – A durable, waterproof surface ideal for concrete formwork
Step 10: Surface cold & hot pressing
The laminated panels undergo an additional cold press and hot press cycle, ensuring the surface adheres firmly to the plywood core. This enhances structural integrity and improves the bonding strength of all layers.
Step 11: Final sanding & Precision cutting
To achieve exact dimensions, the plywood is re-sanded and cut to standardized sizes. This step ensures perfectly smooth surfaces, accurate dimensions, and safe, well-finished edges.
Step 12: Quality inspection & packaging
Before shipping, the plywood panels undergo thorough quality control checks, including thickness accuracy, moisture content verification, surface finish assessment, and strength testing. Once approved, the products are packaged and prepared for delivery.
