- VTC Calculator
VTC200 Casting Program Settings Calculator
Recommended starting settings for ceramic-crucible casting of high-temperature alloys.
Adapted for vacuum melting with pressure-assisted casting.
The model is intentionally kept simple and practical: alloy type, density, metal weight, mold temperature, and casting style.

Core logic:
Smaller metal volume in a ceramic crucible usually means higher temperature loss during tilt and overflow. The calculator compensates by increasing recommended temperature, keeping heating active slightly longer, starting assist earlier, and increasing tilt speed in a controlled way.
Pressure assist start angle:
In this version the recommended practical range is intentionally limited to 60–90°, because the total tilting movement of the VTC principle is 90° and starting assist too early is usually not practical.

Why this recommendation:
–
–
This calculator provides recommended starting settings, not absolute final machine truth.
Final optimization should always be done with real castings, real flask temperatures, and real tree geometry.
