🔏 Wax Seal Press: Stefan Squeeze Flow, Cooling and Imprint Depth (2D)

Side view of a blob of hot sealing wax squeezed between a seal matrix and paper while it cools and stiffens. Set the press force, the size of the blob, the wax and matrix temperatures, the viscosity and its activation energy, and the target thickness, and see how the wax thins and spreads, how its temperature and viscosity change, when it sets and whether the imprint fills before that. The squeeze flow, the volume, the cooling rate and the force scaling are checked numerically, with four in-page numerical checks.
