The machine can be used alone, can also be used to form a mechanized assembly line, and can also be used to form a semi automatic production line. The machine adopts pneumatic multi contact compaction, and the specific pressure is moderate. The number of contacts is 48, which is suitable for complex model. This machine pressure shock when the contact side of sand compaction, and table together with shock, the sand hardness is high and uniform. This machine adopts pneumatic spring buffer microseismic mechanism, so no special requirements on the ground.

The machine starting mode adopts the connecting rod synchronous shaft structure, the speed control of the gas pressure, the mold synchronization is good, the speed control is free.
