a.SPB200-800/DZ/DF Block Molding Machine (Typical) mould are welded by strong rectangle tube
and steel plate with high strength frame, keep more safety of the machine;
b. All block mould frames are treated by heat-treatment to release the welding stress, so that the
frames would not deformed;
c.After heating treatment, all mould frames are processed by sand blasting treatment to keep the
rust away, than under coat and finishing coat are greatly improved anticorrosion performance and
long life;
d.Adopts three Germany gauges and safety valve for multi-safety protection. The machine will be
tested by water pressure and steam (many steps), ensure the machine more stable and safety.
2. Steam system:
Three ball valves, comparing one big steam valve, saves 20% steam, with ISO-standard butterfly
valves, greatly improve stability and long life
