Extrusion plate
The extruded board is a subgroup of the particle board .
It consists of wood chips and an adhesive. In contrast to the flat press plate , the chips here are preferably at right angles to the plane of the plate.
In order to achieve this, during the production of solid extruded panels, the chips are scattered into a heated press channel and compressed with a piston. This means that you can use leftover veneer, rinds or even wood flour , for example. Because of this cross-sectional structure, however, they only have a very low flexural strength and are therefore almost always planked with veneer or wood fiber board, for example .
In the case of extruded tubular plates, there are several heating tubes in the press channel along the pressing direction during manufacture. The resulting cavity makes these panels very light and is used, for example, in door leaves or wall elements.
