FEATURES AND DESCRIPTION

PLYWOOD

VISA-PROM

Plywood is one of the highest-quality and most durable layered wood products. As such, plywood is mostly used in the field of furniture manufacturing, construction, shipbuilding, the aerospace industry and the packaging industry. 

Plywood is a layered wood product in which several layers of wood are glued together in order to enhance the physical and mechanical features of the board compared to solid wood. The number of layers in the board is not limited. Boards are made in various qualitative categories and dimensions, all as per the customer’s request.

Due to its sensitivity to the effects of external factors, proper storage and careful handling are recommended. Our advice is to store plywood boards before installing and working with them under the same conditions to which they will be exposed at the place of installation.

POPLAR

Poplar plywood is exceptionally resistant to moisture and as such is recognized for its durability. We manufacture poplar plywood boards through several procedures using waterproof adhesive. Some of the important features of our poplar plywood boards are that they are relatively light, stable, solid and non-porous.

MANUFACTURING AND PROCESSING

Plywood is made of high-quality types of wood, using highest European standard category A1 and E1 adhesives. Plywood is the generic name for various types of boards made of wood layers of up to 7mm of thickness, glued together. The number of layers of veneer is formed based on the customer’s request, and it is mostly odd.

The surface of the boards is fine-finished using grinding tools, which ensures highly precise dimensions, as requested. 

LVL boards

In addition to plywood, Visa-Prom’s offer also includes LVL boards. These are special-purpose boards with layers all stacked in the same direction.

The majority of plywood and LVL boards are exported to EU countries (over 90%) in accordance with strict customer demands. These products are exported to Germany, Romania, Greece, Italy, and Bosnia and Herzegovina.

WE CAN'T AFFORD TO BE UNPRODUCTIVE

We manufacture standard-sized plywood, but we also cater to our customers’ special requests for dimensions.

THE PRODUCTION PROCESS

Plywood production is a process which combines all of the processes which involve veneer production steps, as well as subsequent steps in which veneer is classified into finished product and semi-finished product which becomes part of further plywood production.

SANDWICH FORMATION

The composition (sandwich) formation phase is carried out on a 12 meter-long and 1.4 meter-wide machine table. A powered infinity plastic and rubber belt glides over the table. The dimensions of the belt are identical to those of the press.

The sandwich formation process implies alternate stacking of veneer sheets with and without adhesive until the final number of sheets in the sandwich is reached, while making sure the first and last veneer sheet contains no adhesive.

PRESSING

Once the adhesive has been applied and the composition (sandwich) formed, the board is placed into the press and then pressed, where the adhesive is polymerized under the impact of pressure, temperature and pressing time, which results in sheets permanently bonding and forming a veneer board. As previously mentioned, the dimensions of the press are identical to those of the belt, i.e. 11.5m long, 1.4m wide, with 160mm of space between the upper and lower press surfaces. The baking temperature is approximately 100-115 degrees Celsius.

Our production facility includes a single downstroke hot press. During pressing and under the impact of temperature which, depending on the type of pressing, ranges from 90 to 145 degrees Celsius, the adhesive is pressed into the farthest central layers of the sandwich and that is where the polymerization of the adhesive takes place.

Under the influence of the said factors, the thickness of the veneer sheets, i.e. of the board itself, is reduced. This reduction in thickness is called “pressing”, which is a combination of elastic and plastic deformations of wood. Plastic deformation of wood leads to a permanent reduction in thickness until it reaches the desired level.  

COOLING

After pressing, the process of cooling and conditioning the boards is initiated with the aim of preventing deformation of the boards. In other words, stress equalization inside the boards is carried out, as well as equalization of moisture and cooling of the board.

FINAL ACTIVITIES

The treatment process does not end here. The next step includes grinding and cutting the board into its final lengths and widths (formatting). This is followed by repairs to the face and back of the boards, after which their quality is determined. Incidentally, thanks to these processes, plywood sold on the market has smooth edges and texture. Every finished plywood product has the desired quality rating. Finished plywood products are divided into two categories and marked for outdoor or indoor use.

The final step is to mark the boards and store them in the warehouse.

QUALITY

It bears mentioning that each production step and the overall quality level are constantly inspected and monitored.

Veneer drying process
Hot air kiln

Veneer drying is the most important stage of production when it comes to veneer quality. Kilns are the largest energy consumers in production and consequently, we pay great attention to this production process.

Once the roundwood has been cut into raw veneer, the initial moisture of the boards is very high. Depending on the type of wood, the moisture content can be over 100%. This means that the percentage of water in the material is higher than the wood mass. The percentage of water in poplar is extremely high and can exceed 150%. The high moisture content in raw veneer causes heavy weight per m3. 

Veneer drying process
Multi-level kiln

There are 2 types of kilns in our production facilities which are used in the dry veneer production process: multi-level and hot air. Their use enables us to obtain between 6 and 12 % of moisture, depending on whether veneer is intended for further treatment, i.e. for the plywood production process or whether it is being stored and delivered as such to the customer.

Given that a large part of our production is based on plywood production, in terms of dimensional stability and gluing quality, it is very important for the moisture percentage to be equal along the entire veneer surface.

We should highlight that during veneer production, every production step is carefully monitored in order to maintain the highest level of quality, as evidenced by the quality certificates of our veneer.

THE PRODUCTION PROCESS
PLYWOOD

Once dried, veneer is transported to the plywood and LVL board production facility. Plywood can be prepared in one of three ways, depending on its purpose – by gluing veneer sheets crosswise at a 90 degree angle, by gluing veneer sheets crosswise at an angle lower than 90 degrees into a star-shaped structure for special-purpose boards, and by stacking and gluing veneer sheets with codirectional wood grain for the purpose of obtaining an LVL board. 

DELIVERY OF
PLYWOOD

Plywood is manufactured for a specific customer, therefore the storage process does not last long. Once the work order has been completed, plywood boards are stored in the warehouse until it’s time for them to be loaded onto a transport vehicle. Given that deliveries take place daily, storage time in the warehouse is kept to a minimum.

Depending on the arrangement with the customer, goods are either delivered to the customer’s address or are taken over directly from the factory warehouse.
