Compared with manual ejection devices, the EJ2 significantly reduces the physical effort required by the operator. Its pneumatic operation ensures a fast and consistent workflow while improving the reproducibility of test results. At the same time, the risk of injury is minimised.
Uniform and controlled ejection of test specimens is essential to prevent any alteration of their structure. Mechanical stress can influence the results of subsequent tests and compromise measurement accuracy. The EJ2 ensures that specimens are always removed under identical conditions, providing a reliable basis for consistent and comparable test results.
Many foundries still use testing equipment from a time when measurements were performed largely manually. Manual operation and hydraulic systems are more prone to errors and often require greater maintenance. In addition, analogue displays can make the precise and unambiguous reading of measurement values more difficult, which may lead to misinterpretation of test results.
Our testing equipment significantly reduces these influences. Automated testing procedures ensure that measurements are carried out independently of the operator, with a high level of accuracy and reproducibility. This helps improve process reliability while supporting consistent quality control in the laboratory.
