With the WJ1 Wet Tensile Strength Tester, you can determine the wet tensile strength of molding sand within minutes and adjust the bentonite content with precision. The system performs the measurement automatically and displays the result digitally in N/cm² after approximately one minute.
By monitoring wet tensile strength before pouring, foundries can improve process reliability and reduce rework, casting defects and scrap. Fast, accurate measurements support consistent mold quality and help maintain stable production conditions.

Many foundries still rely on testing equipment developed in an era when measurements were performed largely by hand. Manual operation and hydraulic systems are often more prone to errors and require increased maintenance.
In addition, analog displays can make measurement values more difficult to read accurately and consistently, which may lead to misinterpretation of test results. Since testing speed often depends on the operator, measurement results can vary from one user to another.
For reliable process control in molding sand testing, however, objective and reproducible measurement data is essential. Our testing instruments significantly reduce these influences. Automated testing procedures ensure that measurements are performed independently of the operator, delivering precise, consistent and repeatable results every time.
Together, we discuss your requirements, operating conditions and project goals. Based on this information, we develop a measurement solution tailored to your specific application and testing needs.
