How and where is plywood produced?

Answer 1

Plywood is manufactured by slicing or rotary peeling thin (<2.5 mm) sheets of material (veneer) from a flitch or log, and then laminating three or more veneers into a rectangular sheet --- perhaps 1200 mm × 1200 mm for very thin sheets otherwise 1200 mm × 2400 mm. Laminating an odd number of plies (3, 5, 7 ... ) reduces warping. Increasing the number of plies increases the resistance to shearing forces.

Answer 2

Plywood is made from 3 or more thin sheets of wood which are glued together, usually in a hydraulic press. Each sheet has its grain at right angles to the grain of the sheets on either side of it. The total number of sheets must be an odd number; if not the sheet of plywood will eventually curve in two different directions, forming a saddle-surface.

Answer 3

Plywood is made of three or more thin layers of wood bonded together with an adhesive. Each layer of wood, or ply, is usually oriented with its grain running at right angles to the adjacent layer in order to reduce the shrinkage and improve the strength of the finished piece. Most plywood is pressed into large, flat sheets used in building construction. Other plywood pieces may be formed into simple or compound curves for use in furniture, boats, and aircraft.

Answer 4

Ply wood is produced all over the world as it is a fairly simple process.

Multiple layers of timber veneers are glued to each other with each layer's grain running at right angles to the one below it. This gives it strength and stability. Odd numbers are used as this prevents the timber from warping.

There are many types of wood used but the process has come in for a little criticism from people concerned about the volatile chemicals used in its production. It is however very versatile and relatively cheap.

Answer 5

Plywood is a man-made product. Its made by shaving wide thin layer of wood from raw timber. These are then laminated so the grain one one layer is vertical and the next it horizontal. This adds strength to the final board. Finally when the thickness of the final board is nearly achieved a "finish layer is applied". This will be a laminate of normally a higher quality wood i.e beach, oak walnut etc depending on what final finish is desired. between each layer is a very powerful glue. The board is the squeezed together and allowed to dry. Its cut to size and then you have the final product
