With the automatic Sand Rammer RJ1, standard test specimens can be prepared independently of the operator and with a high level of repeatability. The system was developed as an alternative to manually operated rammers, where test results can vary significantly depending on the user.
By automating the compaction process, the RJ1 creates consistent conditions for specimen preparation. This improves reproducibility and provides a reliable foundation for all subsequent molding sand tests and quality control procedures.

The RJ1 Automatic Sand Rammer produces test specimens with high repeatability and minimal operator influence. The pneumatic compaction process runs automatically, ensuring consistent test conditions and reliable results.
Two-hand operation improves laboratory safety, while adjustable ram strokes and automatic specimen height measurement provide maximum flexibility and process control.
Many foundries still use testing equipment designed for largely manual measurement procedures. Manual operation, hydraulic systems and analogue displays can increase maintenance requirements and make measurement results more dependent on the operator.
For reliable molding sand testing, however, objective and reproducible results are essential. JUNG Instruments testing systems minimise these influences through automated testing procedures, ensuring precise, consistent and operator-independent measurements.
