Sengon Wood Barecore, the cheap wood panel

Barecore is an intermediate product in the modern woodworking industry. Barecore is a wood panel made from pieces of wood that are glued and laminated together. As wood laminated board, barecore is produced and marketed with standard plywood size 2400 mm length x 1120 mm width. Barecore in the woodworking industry is used as interior (core) to make panels for finished products such as furniture, cabinets, flooring, or other wood panel products. Barecore is an ideal core substrate for the plywood or wood veneer panel. Barecore is another alternative to replace the m.d.f. or particle board in the woodworking industry. Wood veneer from the exotic wood, such as can be laminated on the barecore on one side or both sides to make wood veneer plywood. The other material, such as decorative paper, vinyl, or melamine, can also be attached to the barecore panel to make an engineered panel. If needed, the layer of slice wood can also be used to make a wood panel with a more wood-looking appearance. Compared with the m.d.f. or particle board, the barecore has some advantages. It is stronger, lighter, and more wood-looking. With the right process and selection of wood materials, the barecore is cheap and stable. The barecore with thicker size can also be used to make wood components.

Sengon wood to make barecore 

Although barecore can be made from pieces of wood from the wastes from other woodworking industries, most barecore factories produce their product with special wood. The Sengon wood is the most used to make barecore. Sengon, which is inexpensive, light, and easy to handle, is very ideal to make barecore. The sengon wood has a very short life. With a suitable climate and the right plantation system, the timber can be harvested at about 6 years old. The cultivation of the sengon wood is relatively easy; the wood is abundant. Some areas in Indonesia, such as Magelang, Temanggung and Wonosobo are well known as sources of the sengon timber. In this area there are many sengon barecore or plywood and industries as well as the sengon plantation.

the advantage of Sengon wood barecore:

• Lightweight

Sengon wood is lightwood. The Sengon barecore is lightweight, which makes the material easier to transport and reduces the overall weight of furniture, and the panel resulted. 

• Inexpensive

Sengon trees grow very fast; they can be harvested in about 6 years of age. The wood is inexpensive, much cheaper than other woods such as teak or mahogany wood. Barecore panels are also more cost-effective compared with solid wood panels. Panel made from barercore with premium wood veneer will make the beautiful wood panel with less prices than solid wood. 

• Structural Stability

Wood barecore is made from the wood pieces that are glued and laminated. With proper gluing, it offers good structural stability and resistance to warping and bending. 

• safe from insect 

Sengon wood is highly resistant to the wood bug. Naturally, the wood has chemicals that prevent the wood beetle bug and make the wood free from the bug. 

The process to make barecore is very simple. The wood from the log is cut and dried. The wood pieces in similar sizes are laminated and glued together to form wide and big panels. The size of the barecore is usually a similar size to plywood, MDF, or particle board, although any other special size can also be produced. As with other woodworking products, the drying of the wood is very important. The wood pieces must be completely dry before laminated. The m.c. timber 8% is recommended. The gluing process and the environment condition may bring the MC or the barecore product to about 10%. But the higher moisture content should be avoided since of the risk of the wood movement. 

The drying process for the wood for barecore can be done quickly. The wood for barecore does not require very good quality, such as wood for the furniture industry or other woodworking industries. Some small defects, such as cracks or warping, that are not accepted in the wood furniture industry are not problems in the barecore product. Barecore only requires small-sized wood pieces that are dry. If the sengon wood is used, then drying time can be done within 5 days or even less, a very short time compared with the other wood-drying process for hardwood.
 

The gluing process is another important thing to be considered. The glue will emit the gas in its drying process. The gas emmission will affect the barecore panel quality. Some states require certain VOC limitations for their products. And to fulfill that, the proper glue is absolutely necessary. The gluing process can be done with hot press and cold press, and both each provide its advantages and disadvantages.

The laminated wood panel needs the sanding process to make a flat and even surface barecore panel. The wide belt sanding machine is used to do the sanding process. After a flat surface is obtained, then the barecore should be stacked and wrapped to keep its moisture content. The barecore panel at the open surface will tend to absorb water from its surrounding air and risk getting problems since the wood is swelling and shrinking.  See our previous article: wood moisture on the plywood
