The invention discloses a production technique of EPS (expandable polystyrene) foam articles. The production technique is characterized by comprising the following steps: pre-foaming, curing, feeding, preparing mould, heating and forming, water cooling, vacuum cooling, demoulding, trimming, drying, trimming, packaging and storing in warehouse, and the production technique improves the compressed air, water circular cooling and drying process. The technique disclosed by the invention has simple and reasonable technique procedures and utilizes two paths of compressed air supply systems, so that the pipeline pressure is very stable, an electromagnetic valve acts flexibly, a cylinder switching valve quickly and reliably acts, and a cooling water circulating system can quickly cool to improve the cooling efficiency, save the electric energy and vapor and reasonably utilize the energy sources; besides, a mixed mode of high and low temperature air is used, so that the articles are not deformed or expanded irrespective to the foaming density, the drying time is shortened and the resources are reasonably utilized.
