Materials & Processes • PLYWOOD MOULDING


Thin 2-D or 3-D wooden parts are often realised by means of plywood moulding. Three, five, seven or more layers of veneer are glued together depending on the desired thickness and stability. At first the veneer sheets are cut to size. Then the layers are covered with an adhesive and put on top of each other crossways so that the grain runs at a 90 degree angle. Finally pressure is applied. This can be done by means of male and female moulds which press the veneer into the desired shape. One can also use a vacuum press. The veneer is placed on the mould and covered with a strong foil. A vacuum is created under the foil, pressing the veneer into the mould with great force and high precision. Once the adhesive has dried, the hardened veneer is removed from the mould. The final shape is arrived at by sawing or milling.

With plywood moulding high stability and three-dimensional geometries become possible with little material thickness. Moulded plywood is used for the backrest of PROFILE CHAIR and the profiles of FRAME SEAT.
