Wood drying refers to reducing the moisture content of wood prior to its use. It is the process of reducing its moisture contents to an average equilibrium with the atmospheric conditions of the locality of use. It is done so that when in use the further dimensional change that is contraction and expansion due to seasonal changes is kept to a minimum.
Advantages of wood drying:
Kiln seasoning is drying of timber by keeping it in closed chamber in controlled temperature, RH and air circulation environment. In Kiln, the timber is stacked in closed chambers where the equipments are fitted to manipulate and control temperature and relative humidity of drying air, its circulation through the timber stack. The drying is faster, precise and better than air seasoning. Kiln seasoning enables wood to be dried to any desired moisture content regardless of weather conditions. It normally takes 2-5 weeks for wood drying in kiln. Almost all commercial timbers of the world are dried in industrial kilns.
Finger jointing results in much higher quality and stronger pieces and components, while dramatically reducing waste in our industry where the cost of raw materials is rapidly increasing.
If the joint is cut accurately the ‘fingers should fit together without any gaps and the glue ensures that they are virtually indestructible.
Strength – Finger joint lumber is as strong as, or stronger than conventional dimension lumber;
Assume a wooden pencil, break it in 2 parts! Oh yes that’s easy. It breaks. But now try breaking those two smaller parts. Not that easy. This is how Finger Joint works. When smaller wooden panels are joined through interlocking system, the tensile strength increases by 2.5 times.
Stability – Warping and twisting is significantly minimized;
Straightness – Each piece is straight and true, as any bow or crook is absorbed in the joint;
Quality Control – Rigorous assurance controls ensure that the joints are tested for strength, water resistance and conformance to standards
Consistency – It’s made from small pieces of high quality wood ensuring the end product is always of consistent premium quality.
After the small wooden panels are joined through Finger Joints in a vertical format, Butt Joints are used to join woods in a horizontal form.
Butt Joint – One piece of wood is butted up against another, then fixed in place with glue and clamped in a neumatic high pressure clamper .
It overcomes the limitation of size of wood available. Hence any size of wood can be developed with the help of Butt Jointing. Also only seasoned wood is taken for the Butt Joints therefore includes all the benefits of highly seasoned woods. Which ensures in high level of control over expansion and conrtraction of woods. It also results in higher strength properties, leads to better results in wood working, machining and finishing. Drastically minimizes decay, fungal attacks and ensures better dimensional stability, Minimizes other seasonal defects such as warping, bending, cracks etc.
For further enhancement of strength in wood especially for high density wood (above 30mm thickness), we incorporate multiple metal enforcements.
