1. Moderate pressure, no special requirements for sand, and the number of contacts more than 60, suitable for complex model modeling.
2. During compaction, the frame is free of force. The contacts extend downward, the pressure strength is the internal force of compaction.
3. The effect of shock compaction is good. The hardness of the sand mould is high and even.
4. This machine adopts the spring full buffer pneumatic micro vibration mechanism, so it has no special requirement for the foundation, and the mould lifting adopts the connecting rod.
5. Synchronous shaft structure, speed regulation of pneumatic oil, good mould synchronization with free speed control.
