A famous Italian song
says that it takes wood to make a table and it takes a tree
to make wood.
If this table was made
by several wooden slats bonded together or if in addition to a table, we wanted
to make a design chair with curved corners, or if a famous archistar has
designed an auditorium finished with curved wooden profiles, how could we do,
starting from a straight trunk?
Technology helps, as usual. In the wood processing sector, technology plays an increasingly important role.
There are many solutions but focusing on high frequency technology means that the wooden parts’ manufacturer can benefit from the modernization of its equipments: instead of using traditional hot water or diathermic oil with gas boiler, diesel oil, electric resistors and so on, he will work with high-frequency dielectric heating.
To get this kind of heating it is necessary to install a high-frequency capacitive generator beside the press, which can perform many typical processes of the wood industry, aimed at the solid wood processing and the plywood production, and their various uses, of course.
One of the treatments is the quick bonding of solid wood for producing Blockboard panels, glued wooden beams, laminated elements for windows, X-LAM panels (CLT), multilayer parquet and other applications.
The use of this
technology also includes production of curved plywood, bending of
solid wood and production and bonding of chipboard panels, cork
blocks and other materials.
Even the drying
processes of solid wood are made with high frequency generators, which make
it non-deformable for very long time, giving it those characteristics of
strength and quality.
If there are many uses of high-frequency technology, there are also many
advantages offered by this technology.
The increase in productivity is undoubtedly one of the most evident
positive points because the heating time is faster. Why is the heating time shorter? The answer is simple: heat is
not transmitted by convection, but it is generated inside the material itself
without transmission losses and likewise in case of bonding, the heat is
generated directly in the glued junctions between the slats.
Furthermore, the high frequency generator ensures also high
efficiency in energy transfer and in heating control within the
default range, allowing the product to be heated in an even manner, preserving
its chemical and physical characteristics without deformation.
Preheating takes place immediately and this feature, together with the
thermal loss reduction in the working space, reduces energy consumption with
the consequent efficiency of electricity costs.
Speaking about savings and sustainability - ones of
the preferred topics for companies in recent years due to energy costs and the
continuous improvement of social policies - also concerns lower costs for molds
manufacturing and the elimination of any noise or smoke produced by energy
source. This also allowed the working space, where operator moves, to be healthier.
HF technology is widely used in other manufacturing sectors as well.textile, paper, leather and even food industries can take advantage of its benefits.
