Abstract

A process of moulding blanks in sheet form comprises forming a fleece of lignocellulose-containing particles together with at least one thermoplastic binder on a substrate and then heating the material to the processing temperature of the binder and pressing the material into sheets, the process including a finishing/pressing step in which the sheets are cooled. Preferably, the mixture of lignocellulosic and thermoplastic particles (e.g. 60:40 wood particles: binder) is first precompressed and then heated and cold finish/pressed. The mixture may additionally be heated before or during the precompression step. A separate final cooling step is not necessary, and the blanks can be directly stacked for storage. The finished blanks can subsequently be post-formed under heat and pressure to make a variety of products.
