Many foundries still use testing equipment developed for largely manual measurement procedures. Manual operation, hydraulic systems and analogue displays can increase maintenance requirements and make accurate interpretation of measurement values more difficult.
In addition, the speed of the ramming process often depends on the operator, which can lead to variations in test results. Reliable molding sand testing, however, requires objective and reproducible measurement data.
JUNG Instruments testing systems significantly reduce these influences. Automated testing procedures ensure precise, consistent and operator-independent measurements, providing a reliable basis for process control and quality assurance.
