Chipcore–Its Characteristics and Production

Chipcore made from kiln-dried leftovers in furniture operations is described and its properties discussed. Comparative test results on the material as produced from many wood species and sources are presented with a description of a chipcore manufacturing plant now under construction. Chipcore is defined as a relatively thick (3/8 inch to 1-1/4 inch) panel produced by curing a suitably selected and prepared mixture of wood particles and binder under conditions of heat and pressure which will permit the polymerization of the binder and the formation of a stable mat having properties of strength, stability, surface, and dimensions suitable for its intended use. The panels are usually formed flat but may be produced in curved or other shapes if desired. Chipcore is widely used in the production of cross banded and veneered panels where it takes the place of edge-glued lumber core. It may also be used as sheathing and subflooring. The type of wood used for chipcore has no direct effect on the strength of the boards produced. A sketch of the manufacturing process for a new plant under construction is given. The capacity of the new plant will be 1000 Sq. ft. of 3/4-inch board per hour. It is estimated that the new chipcore operation will ultimately reduce the lumber requirements of the parent plant by 2 million board feet per year.
