Behind the Scenes at a Veneer Manufacturing Unit /
Wood veneers, which are essentially thin sheets of wood, are a great way to decorate your home or office in the hues of wood, while at the same ensuring economy is maintained.
The product is, in fact, economical in more than one sense. Apart from being cost-effective, the production of wood veneers too involves a process that respects the precious resource wood is, by minimizing its wastage. In fact, between 800 and 1000 sqm of veneer is produced from just one cubic meter of lumber. The highly efficient production process undertaken to achieve this is briefly described below.
As soon as the logs arrive at the manufacturing unit, they are classified by species and stored in the log yard.
Further, they are kept under optimal humidity conditions by soaking them in ponds of water or spraying them with water, as the needs dictate.
The bark is then peeled off while ensuring that evenness is maintained. At this stage, great care is taken to ensure that the logs do not get damaged.
In order to ensure uniform slicing, the logs are then kept completely submerged in steamers at temperatures of 80 - 100℃ for a period of 18 to 72 hours. To achieve the maximum efficiency, logs are to be cut within an hour of the completion of cooking.
Once the pressure and knife bar settings are set to an accuracy of 0.1 mm, so as to ensure slicing that’s perfect, one of two types of veneer slicing machines - a horizontal/vertical slicing machine or a peeling machine - are set in motion to obtain thin wood veneer sheets from the log, even as a heating system soaks up any moisture that is released during the process. There are different methods of slicing that can be undertaken, such as flat slicing, quarter slicing, or rotary cut, to obtain different types of veneers.
Here, the veneers which are still moist are dried in a jet drier which also has the effect of flattening them.
Here, an expert carefully assesses the veneers for quality according to strict quality standards.
The veneers are then clipped to produce sheets of rectangular dimensions, after which it is put through the glue machine which bonds the edges of the veneers.
Here, veneer matching is undertaken using the application of heat and pressure to ensure a consistent match is obtained.
Finally, the wood veneers are measured, labelled with indications of length, width, etc., packed with protective polyethylene and readied to be transported.
