In order to know the influence of laboratory temperature on the properties of the quick-heating investments, the setting expansion, heat expansion roughness of mold and casting accuracy were measured at 16℃,23℃, and 30℃ under 60% humidity. Results were as follows:
1. With a rise in room temeperature, the setting expansion was increased.
2. With a rise in room temeperature, the heat expansion was decreased.
3. With a rise in room temeperature, the roughness of casting was increased.
4. With a rise in room temeperature, the surface of mold for dimple was increased.
5. With a rise in room temeperature, the casting shrinkage was decreased.
