1. PLYWOOD PRODUCTION FACTORY

- The plywood production workshop must meet technical and safety standards during operation.

- The workshop is spacious and solid to ensure the production process is continuous in all weather conditions.

- The areas are clearly divided to ensure the production of high quality plywood.

- The closed production line from input materials to the final product.

2. TYPES OF MACHINES

- Slicing machine

- Dryer

- Hot press

- Cold press

- Automatic board stacking line

- Trimming and sanding machine

- Types of plywood production machines

 

3. PLYWOOD PRODUCTION PROCESS

The plywood production process usually has 3 main stages, which are:
Stage 1: Harvesting wood

* Selecting suitable trees (broadleaf or coniferous)
* Using a cutting machine, take the trunk, remove branches and leaves, then transport to the factory for processing
* Harvesting wood for plywood production

Stage 2: Wood processing

• After being brought back, the trunk will be soaked in a water tank for a certain period of time. This helps the machine to easily peel the bark and cut into many sizes.
• Wood processing after harvesting

Stage 3: Plywood production

• Step 1: Peel and cut the wood into pieces according to the required size
• Step 2: The wood is put into the leaf cutter to form thin wood panels
• Step 3: The thin wood panels are put into the production line to be cut according to the required size and classified.
• Step 4: The thin wood panels are put into the dryer to reach the specified humidity
• Step 5: Use scanning technology to check for defects on the wood panels and proceed to correct the errors.
• Step 6: Clean and evenly coat both sides of the plywood with adhesive, stack the plywood panels on top of each other according to the required thickness
• Step 7: Put the plywood panels into the cold press to flatten and ensure the glue is evenly distributed
• Step 8: Put the plywood panels into hot press for the specified time so that the thin wood panels are tightly bonded together.
• Step 9: After hot pressing, the plywood is cooled and put into the trimming and sanding machine to remove the edges and smooth the surface.
• Step 10: Check the quality of the finished product

Classifying and packaging plywood

After completing the 3 stages, the plywood will be packaged according to regulations and stored in the warehouse or distributed to the necessary place.

4. PLYWOOD PRODUCTION STANDARDS

- After being dried, the thin wood panels are stored for at least 24 hours and kept at a humidity of 6-8%

- Choose the right glue. Commonly used glues are protein glue, Urea-formaldehyde glue and Phenol-formaldehyde glue

- Pressure conditions must meet standards

- The plywood pressing process is strict and in the right order.
