Plywood is obtained by gluing wooden sheets at a pressure of 100 to 150 N/cm2 and a temperature of 100 to 130 degrees Celsius. Plywood is made up of three or more thin layers of wood. These layers are bonded together with an adhesive.

Glued sheets are loaded into a multiple-opening hot press. presses can handle 20-40 sheets at a time, with each sheet loaded in a separate slot.

When all the sheets are loaded, the press squeezes them together under a pressure of about 110-200 psi (7.6-13.8 bar), while at the same time heating them to a temperature of about 230-315° F (109.9-157.2° C).
