The polystyrene foam block making machine mould are welded by strong rectangle tube and steel plate with high strength frame, keep more safety;
All block mould frame are processed by heat-treatment, the welding pressure will be released, so the frame would not deform easier, accurate machining process keep non-leakage;
After heating treatment, all mould frame are processed by sand blasting treatment to get rust prevention, so under coat and finishing coat are greatly improved anticorrosion performance and long life;
Adopts three Germany gauges and safety valve for double protection, the machine will be water pressure and steam many testing, ensure the machine more stable and safety.
