• Support tools – including a brush and shovel for sample handling.

This simple yet robust structure ensures both accuracy and reliability while keeping maintenance requirements low.

4. Basic Working Principle

The RSM tester operates on the principle of thermal gradient measurement:

1. The heat-conducting metal beam is energized to generate a controlled temperature gradient across its surface.

2. Resin-coated sand samples are evenly spread onto the beam.

3. As the beam heats up, resin within the coated sand begins to melt and adhere to the beam surface.

4. After a fixed period, a brush removes the loose sand, leaving only the melted particles adhered.

5. The temperature at which adhesion occurs is recorded as the melting point of the resin-coated sand.

This method provides direct, accurate, and practical results, reflecting the actual performance of coated sand during casting processes.
