• Name: Lost Foam Special EPS Pre-epxander Machine

        • The equipment mainly used for foaming EPS beads for lost foam production .
           
        • It adopts EPS polystyrene , STMMA copolymer resin and EPMMA polymethyl methacrylate as raw material of lost foam. It adopts advanced electrical and pneumatic components to ration pre-expander time , controls barrel temperature and pre-expander time automatically.
           
        • The machine is equipped with hot air dryer system without agglomeration and wall-sticking , raw material after pre-expander is dry and uniform which shortened the curing time of natural aging
