**CASTING PROCESSING PARAMETERS**

| Casting temperatures | Metal- from [℃] | Metal-to [℃] | Flask- from [℃] | Flask-to [℃] |
| --- | --- | --- | --- | --- |
| Thin(below0.5mm) | 990 | 1020 | 560 | 600 |
| Medium(from0.5to1.2mm) | 970 | 990 | 520 | 560 |

**Stone-in-place casting trees**

Let the flask cool down for 30-45 minutes, then quench in water.

**Trees without stones**

Let the flask cool down in the chamber for 1 minute after pouring. Take the flask out of the machine without shaking it, let it cool for 15 minutes in air, then quench it in water.
