Production process flow of two time molding film faced plywood | Jsylvl

The production process of two-time molding film-faced plywood involves multiple steps to create a high-quality material with specific characteristics. Here is a generalized flow of the production process:
Veneer Peeling:

Select suitable logs based on wood species and quality requirements.
Peel logs into veneer sheets using a rotary lathe or other peeling methods.
Veneer Drying:

Dry the veneer sheets to reduce moisture content. This can be done through methods like air drying or using specialized drying equipment.
Grading and Sorting:

Grade and sort the veneer sheets based on quality, thickness, and other specifications. Higher quality veneers are typically used for the face and back layers.
Gluing:

Apply adhesive to the veneer sheets. The adhesive used is often a phenolic resin or other suitable waterproof adhesive.
First Assembling:

Assemble the veneer sheets into a panel with the desired number of layers. The number of layers can vary depending on the thickness and intended use of the plywood.
First Hot Pressing:

Place the assembled veneer layers into a hot press. Apply heat and pressure to cure the adhesive and bond the layers together. This process is known as the first hot press.
Cooling and Inspection:

Allow the pressed panels to cool.
Inspect the panels for quality, checking the bonding and overall integrity of the plywood.
First Sanding:

Sand the surfaces to achieve a smooth and uniform finish.
Film Application (First Time):

Apply a layer of film (phenolic or melamine-impregnated paper) to the surface of the plywood. This film serves as a protective and decorative layer.
Second Gluing:

Apply adhesive to the film-covered surface of the plywood.
Second Assembling:

Assemble the veneer sheets with the film into a panel.
Second Hot Pressing:

Place the assembled veneer layers into a hot press again. Apply heat and pressure to bond the film to the plywood surface. This is the second hot press.
Cooling and Inspection:

Allow the plywood to cool.
Inspect the finished panels for quality, ensuring that the film is properly bonded and that the plywood meets specified standards.
Second Sanding:

Sand the surfaces again to achieve the final smooth and uniform finish.
Cutting and Edge Sealing:

Cut the plywood panels into standard sizes or as per customer requirements.
Seal the edges to enhance the moisture resistance of the plywood.
Quality Control:

Conduct quality control checks on a sample basis to ensure the plywood meets industry standards and customer specifications.
Packaging and Shipping:

Package the finished plywood for protection during transportation and storage.
Ship the packaged plywood to distribution centers, retailers, or directly to customers.
It’s important to note that specific details of the production process may vary among manufacturers, and the use of advanced machinery can streamline certain steps. Additionally, adherence to industry standards and quality control measures is crucial to producing high-quality two-time molding film-faced plywood.
