1.The eps block moulding machine with vacuum adopts PLC and touch screen for controlling the mould opening,mould closing,material feeding,steaming,temperature keeping,vacuum cooling,de-moulding and ejecting; 2.The machine adopts high-efficient vacuum system and condensate device to improve moulding speed and reduce the moisture content. Vacuum supported machine is very efficient for making high-density and thick block; 3.The machine is welded from high-quality profile steel,through heat treatment,ensuring high strength of the machine without deformation,and possibility of bearing the expansion force of the high-density product; 4.Adopting advanced moulding technique,the machine is applicable to produce high-density and low-density block and ensure same quality of inside and outside block; 5.The mould cavity surface is coated with Teflon,ensuring easy de-mould and good finish of the block;
