The QR-HTS intelligent high-temperature strength tester is designed for research institutions, engineering colleges, and manufacturing facilities to evaluate the high-temperature performance of inorganic non-metallic materials and molding mixtures. This advanced instrument provides precise measurements critical for casting quality control and material research.

• High-temperature compressive strength of molding sand
• High-temperature heat resistance time (thermal stability) of core sand
• Thermal expansion and expansion force measurements
• Thermal deformation and residual strength under fixed loads
• Room temperature compressive strength (up to 1400℃)

The tester's ability to analyze high-temperature strength variations helps prevent common casting defects including sand flushing, cracks, sand sticking, and sand inclusion. It's particularly valuable for studying water glass sand, phenolic resin sand, and furan resin sand properties.

The system's advanced computer integration allows for offline operation, extensive data analysis, and customizable reporting in PDF format. All test data is permanently stored for future reference and comparison.

The QR-HTS tester simulates sand mold heating conditions by placing samples in a high-temperature furnace. Special servo motors, worm gear reducers, and precision sensors work with the computer-controlled system to automatically complete testing, data processing, visualization, and reporting.
