On the basis of digesting and absorbing the foam molding machine imported from abroad, EPS sheet forming machine manufacturers further improve and improve according to my country’s national conditions. Through the analysis of value performance, the process flow of EPS sheet forming machine is simplified, and its screw is changed. In order to improve its processing capacity and increase product specifications, EPS sheet forming machine manufacturers are also working hard to develop more advanced, safer and more energy-saving products than the present, so that EPS sheet forming machine products can be used in building thermal insulation and alpine regions. The fields of road water insulation and antifreeze have been popularized and applied on a large scale, so that the products of EPS sheet forming machines are in short supply in the market.
