Abstract
The present invention concerns a method and a system to produce refined, compounded products made of plastic materials, such as rapid reaction products like polyurethane foams. Plastic materials are injected in a mould together with loading materials; the mixture obtained during the expansion phase is then compressed. The compression force exercised on said mixture by mobile moulds separate pistons or similar devices must be such that final products have extremely high hardness and density. Said final products can also be realised in the form of tables with high hardness and can be used in the furniture industry.
