Rising tube velocity m/s

Cavity volume cm³

Cavity height mm

Rising tube length m

Tube loss margin %

Rising-tube roughness ε mm

Alloy liquidus °C

Result

Furnace pressure curve

Note — Add the loss margin and a ramp/hold schedule (pre-pressure → boost → hold) for the furnace.

Note — Real pressure also includes friction and dynamic losses; add margin per your equipment.

Note — Curve is physical: pre-pressure → climb (level rise) → hold → release.

Note — Records the pressurization-curve animation as WebM (modern browsers). GIF export needs an external encoder.

Note — Heat loss through the riser tube cools the melt; keep gate temp above liquidus.

Note — Gate temperature from riser-tube loss feeds back into melt viscosity, raising pressure drop and peak pressure (closed loop).

Note — Selecting an alloy auto-fills density, furnace temp. and liquidus.
