The most-widely known feature of wooden materials that makes them a motive to be preferred is warmness of the wood with a low temperature conductivity and its being completely natural and healthy. Furthermore, the resistance of this construction material is quite strong in ratio with its specific weight. Manufacturing products from wood requires much less energy (compared to other industrial materials) which is one of its positive effects on humans health.
The other features of wooden materials: Sound and heat isolation, stability in high temperatures, resistance against shock and vibration, operation and joining with simple tools, no sign of fatigue contrary to metals, rust-proof, resistance against low bases and acids, easy for surface operations thanks to its porous structure, easy to notice the defects, protectable against decaying with several methods, being a rawmaterial of many industrial product through chemical ways, decorativeness in colour and apperance.
SOLID PANEL MANUFACTURING
Stages for manufacturing solid panel can be listed as below:
drying, slicing, eliminating the defects, laths elongation, joining in lengthwise, joining side-by-side, sizing, calibre and packaging.
Drying: The timbers to be used for solid panel manufacturing must be dried up to 10±2% humidity.
Slicing: The dried timbers are sliced according to lengths before the four operations. At this stage, the laths are classified according to the appearance of the wide surface, full length or defect elimination since it is very important in the production of come solid panels which will be manufactured from certain types of trees.
Elimination of Defects or Knots: The operation of eliminating the defects on the sliced laths which do not comply with solid panel standards.
Joining Length: The operation of opening the teeth and pressing the glued materials for joining length in a required standard for the manufacturing of solid panel.
Elongation: The length of the laths subject to above mentioned process are already adjusted to the desired size in the joining machine (FJ), or the laths whose defects were eliminated under computer control are elongated up to the desired length. Full length laths are not elongated.
Criteria of Classification: The solid panel products will be subject to a pre-elimination as per thekey criteria such as type of wood, pattern, colour (if any) and being joined (FJ) or not. Following this classification, the solid panels are operated in five different classes: A/A, A/B, B/B, B/C and C/C, parallel to the ratio of defects on their surfaces.
Side-by-side Gluing (Press): Even when the classified laths progress for pressing, it should be observed how the laths will form a panel by arranging the laths according to their classes beofre pressing. One side of the laths will be glued and given to press.
Sizing: The size of the solid panel sheets which were remained as stacks may not be big as desired and their edges will not be smooth. These sheets will be sized to form them into the desired size and to be mitered, unless otherwise requested.
Calibrated: Since the solid panel products are mostly used for furniture manufacturing, the customers expect that both the two sides will be parallel to each other (calibrated) and that they are purifed from fibers at a medium level. Thus, both the surfaces will be calibrated and 100 or 120 sand solid panel is calibrated upon request.
Packaging: Solid panel is a real wooden product. This product shows a tendency to behave like a solid wood due to ambient relative humidity and temperature. Thus the material needs to be packaged so that the it is not affected from the negative conditions during storage, shipmeny or the storage by the user. The most preferred package type is Shrink nylon. The packaged products are stocked in accordance with the stacking rules.
