3.(vacuum type eps block molding machine)it adopts the mature and advanced molding technics of penetrating and heating, with the advantages of higher penetrability, stronger cohesiveness, less steam consumption, higher molding speed and higher productivity which is over twice higher than ordinary manual or semi-automatic operating. It adopts large diameter pneumatic butterfly valve to increase the heating speed and do its best. 4.After heating treatment, all mould frames are processed by sand blasting treatment to get rust prevention, so under coat and finishing coat are greatly improved anticorrosion performance and long life.
