The machine adopt the jolting technology, so it can significantly increase the compressive stress to make the hardness up to HB90 and upgrade one level about the surface roughness, so it can guarantee the quality
The shock part of the machine is buffer spring, so it can effectively reduce the impact to foundation
The pattern drawing mechanism adopt the cylinder,crank, connecting rod, synchronizing shaft to achieve the synchronism
The control part, it adopts all pneumatic components to achieve the global function, simple operation and convenient to maintenance
The machine is convenient to operate, itcan visual the sand mould, human operation, so it is effective to increase the productivity.
