Production process

Wood-based Panels

Wood-based panels are produced by chipping wood or a similar raw material and then assembling it into a panel-shaped end product.  This makes it possible to use wood fractions that could otherwise only be used as raw material for pulp production or even as fuel. In this way, a comparatively inexpensive raw material is transformed into a high-quality product. Wood-based panels are an important starting material for the wood and furniture industry worldwide.There is a large number of different wood-based materials for a wide range of applications.  The manufacturing process of the three most important types of wood-based panels is explained here:

Particleboard is one of the oldest and perhaps best known wood-based materials. It consists of glued flakes of different sizes, which form a multi-layer structure. The main applications are furniture production and interior fittings.

The term fibreboard includes MDF (medium density fibreboard) and HDF (high density fibreboard). With these types of panels, the wood is not reduced to chips as with chipboard, but even more so to fibres. The result is a panel with a homogeneous structure and fine texture.

The OSB panel is a wood-based material made of large, slender flakes - the so-called strands. The strands are scattered in several layers, each of which is aligned perpendicular to the other. This gives the board similar properties to veneer plywood; it can therefore also be used in structural applications and has a high load-bearing capacity. OSB panels are therefore used as building boards for exterior use, in interior construction as wall panelling or flooring panels or also as formwork material and for the production of packaging.

Recently, mixed forms of all three wood-based panels have also gained popularity on the market, for example OSB panels with a surface made of fine flakes for particularly stressed shelves.

Source product

The raw material for particleboard and fibreboard are cellulosic fibres. These are mainly industrial roundwood, sawmill by-products such as rind, wood chips or sawdust, and used wood. In addition, raw materials such as bamboo, bagasse, rice straw or similar fast-growing fibres are increasingly being processed into wood-based panels. Below the production process of panels is described using industrial roundwood as the raw material basis. Deviations from this production process due to other raw materials are possible.

The optimal raw material for OSB production is industrial roundwood. For the production of strands mainly fresh wood is used to ensure a good elasticity of the strands. In contrast, dry wood is brittle and produces too much fine material when chipped.
