The lovely veneers in your home have traveled quite a distance since they were felled as a wood log in the forest. A great deal of effort goes into creating these gorgeous pieces of wood, and we go into greater information about how wood veneers are manufactured here to help you enjoy them even more.
After being cut in the forest and loaded into the lorry, the tree log is transported to the log yard, where it is categorized by species and preserved in optimal conditions. To keep the timber in good condition, it must be exposed to the appropriate degree of humidity through spraying or soaking in water ponds. This will help to prevent the log from deteriorating, which is common when not given adequate moisture. Related product: Wood Aluminum Panel.
The following step is to debunk the log. Specially developed machinery is used here to delicately scrape the bark of the wood while taking care not to damage the core, from which the veneer will finally emerge.
With the log stripped, the moisture content must now be increased. This will soften the wood fibers, making the following stage of the procedure easier. Steamers with temperatures ranging from 80°C to 100°C are utilized to place the logs into, and the process can take anywhere from 18 to 72 hours. Because the log can quickly dry out, it must be cut within one hour of the operation to retain its quality.
The slicing process used to create the veneer determines how and where a tree log is chopped. Each log already has its identification label, making it simple to see which cuts are being used. The log will also need to be peeled, therefore it will be chopped in half or quarters in preparation for that stage.
The tree logs are sliced into veneer sheets here, which can be done in a variety of methods. A flat slice is the most typical, with the cut occurring parallel to a line through the center of the log, resulting in a tidy, uniform sheet. Another method is the rotary cut, which produces a wide sheet by following the annual growth rings of the log. Quarter slicing ensures that the blade cuts into the growth rings at the correct angle, resulting in a series of straight lines. There's also the rift slice, which creates a comb effect, and the half-round slice, which is a hybrid of a flat slice and a rift cut.
After the veneer sheets are cut and carefully placed in the dryer, the natural arrangement of the log is maintained. Each sheet is dried in a matter of minutes after being exposed to extremely high temperatures of up to 320°F and heat-blasted onto the surface of the material. However, the veneer will not be dry because this method keeps roughly 10% of the moisture content.
After the logs have been dried, quality checks are performed to ensure that they have been cut, peeled, and dried to an acceptable standard. Before going through various identification checks, each page is reconstructed to establish the structure of the original tree log. The wood veneer is carefully analyzed and identified by an expert whose job it is to ensure that the veneers provided to customers are of sufficient quality.
Following that, a clipper is used to generate sheets that are all the same length before the process is repeated to guarantee they are all the same width. This is a critical stage since the precision and angle of the cut will have a significant impact on the final quality of the veneer panel. When the panels are finished, they can be transported to the glue machine, which is used to attach the veneer sheet edges.
This is where the matching process takes place, ensuring that the finished product is consistent throughout. Booking matching, slip matching, running matching, balance matching, reverse slip matching, end matching, and many other approaches can be employed.
The sliced veneers are packaged at the end of the process so that they can be transferred to the next stage of the supply chain. This entails measuring and labeling the stock such that the width, length, and other important information are visible. They are then loaded onto pallets and wrapped in protective plastic before being loaded onto trucks and transported to their final destination.
The thickness of the cut varies depending on the mill that produces the veneer, but for ordinary commercial uses, they are sliced into sheets 1.5mm thick and down to 0.4mm thick. These veneers are utilized to make low-cost products at the thin end of the scale, whereas thicker veneers are used to make high-quality items.
A thickness of about 0.6mm provides good strength and reliability, especially for residential construction. The ideal thickness for construction purposes is 1.5mm to 2.5mm.
All veneers must be attached to a flat, smooth, sturdy substrate that will not expand or contract in response to temperature or moisture fluctuations. The following are the most frequent types of veneers:
1. MDF
This is a low-cost choice that is smooth, flat, and very reliable, and it easily accepts veneer gluing.
2. Plywood
While not as dependable as MDF, it is still a viable option. For large doors, Baltic birch plywood may be a better alternative than heavier MDF, though warping can be a concern with this type of wood.
3. Particleboard
Particle board is another viable alternative, though boards with melamine surfaces must be sanded down to allow the adhesive to effectively attach.
