Abstract
Microwave energy applied to a wood-resin composition such as plywood is used to cure the resin in a very short time, as compared with a conventional hot press process, and yet avoids the arcing and tracking problem that results when R.F. dielectric heating is used to reduce cure time. Pressure is applied to the plywood or other article being made either simultaneously with the microwave energy or shortly after the lather has been applied.
