How is Plywood Manufactured?

Plywood Manufacturing Process involves following steps which are given as follows:

The first step in the production of plywood is the proper choice of quality timber. The most commonly used woods in plywood manufacturing include hardwood species like eucalyptus, teak, birch, and oak, as well as softwood species like pine and spruce. Proper selection of timbers is necessary to decide on the final strength and quality appearance of the finished plywood. Royale Touche used 100% eucalyptus due to its suitability for making high quality plywood.
Once the logs are selected, they undergo debranching, or outer layer removal as part of plywood making process The debarked logs are then cut into smaller sizes for ease of processing in subsequent steps.

As logs have moisture in them, veneer sheets are wet after peeling. Further, these sheets are treated in vacuum pressure treatment chambers (VPT) for imparting resistance to termites and borers. The following step of the plywood making process is drying the veneers to decrease its moisture content which is essential for proper bonding between the glue and wood and prevent delamination or warping of the plywood.
The veneers are dried using large industrial dryers to minimize moisture as part of the plywood manufacturing process. This ensures stability in plywood to resist environmental changes.

One of the most important steps in plywood production is gluing. Dried veneer sheets are coated with adhesive and layers are placed one over other in alternating grain direction which makes the plywood strong as well as resistant to warping or cracking under pressure. Phenol-formaldehyde adhesives are used in most instances for water-resistant plywood. Interior-grade plywood makes use of urea-formaldehyde glue. Pressure on the plywood sheet is evenly dispersed with uniform thickness as the veneers are aligned with extreme care.

Once veneers are bonded and layered, the next step in the plywood manufacturing process is pressing the layers of veneer together in pre-press, followed by pressing under high pressure and heat within hydraulic presses to create a strong bond between the layers.

The plywood sheets are then trimmed to their sizes and shape after undergoing the pressing process. Overhanging edges as well as excess material on the plywood are also eliminated, which will leave the plywood with smooth, even edges. The sheets of plywood are sanded to make the surface smoother. This process of sanding also makes the surface of plywood suited for painting, varnishing, or applying laminate. The amount of sanding varies on the plywood grade with finer sanding for higher grades and lesser sanding for lower grades.

The plywood sheets are then glued with gurjan face veneer on both sides and again pressed in pre-press and hot press for proper bonding. The face gives the plywood additional strength and also gives it a finished look, which can also be directly polished for interiors if desired.

The plywood manufacturing process finally includes a quality check. Cracks, splits, or gaps between the layers in the sheets of plywood are checked. Based on the quality, plywood is graded and only defect free plywood is sent for final printing and dispatch.

Royale Touche Plywood is one of the best plywood brand in India that provides plywood of premium quality, robust strength, and long-lasting durability.

Royale Touche makes an excellent selection of wood that is of high density and strength to provide plywood sheets that are tough and stable. The plywood crafted comes with a smooth finish with natural resistance to moisture and pests.

Royale Touche plywood is known for its longevity and the multiple treatments undergone for resistance against termites and borers.

The superior-quality adhesive along with high pressure compression techniques used by Royale Touche ensure the plywood sheet will not warp or delaminate.

Additional face overlaying and fine sanding make Royale Touche plywood have a smooth surface finish, making it ready to apply various finishes of painting, varnishing, or laminating adding flexibility to furniture makers and interior designers for execution.

Each sheet is stringent quality checked before acceptance to meet the Royale Touche high standards. Sheets showing cracks, gaps, or other defects are removed to ensure that customers receive defects.

Understanding how plywood is manufactured is important for one to know the different steps involved in the process. At Royale Touche, each plywood sheet that rolls out of the production line is as strong and as durable as it needs to be for any given construction project or furniture making. Understanding these stages may help one make informed choices when they go ahead to buy plywood for a project.

How does one check the quality of plywood?
Plywood quality can be checked by looking at the surface and feeling the smoothness of the surface, whether they are free from any gap or void in the layer and even thickness.

Which are the most typical types of wood used in plywood?
Common types of wood that can be used in the plywood manufacturing process include hardwoods, like eucalyptus,teak, oak, or birch, and softwoods, such as pine or spruce. The types of wood chosen determine how strong, attractive, or long-lasting the plywood would be.

What is an adhesive in making plywood?
Adhesive is the glue which sticks veneer layers together by bonding. Water-resistant adhesives are used in exterior-grade plywood. For example, phenol-formaldehyde is used. Interior-grade plywood normally utilizes urea-formaldehyde. The type of adhesive used ensures whether the plywood withstands moisture or not and how long it lasts.
