Inspect a heated billet container, hydraulic ram and profile die. Material exits as a solid rod or hollow tube; area reduction increases exit speed while a capacity check can stall the ram.
• A 3D process cutaway of a billet container, ram, profile die, area ratio and ram force, with labeled components you can select. • Controls: Die profile (Solid Ø10 mm rod / Tube Ø12 / Ø8 mm), Ram speed (0.2-2 mm/s), Mean flow stress (50-150 MPa), Friction allowance multiplier (1-1.5 ), Available ram force (150-750 kN). • Live readouts: Extrusion area ratio; Estimated required ram force; Exit velocity; Extrudate length; Consumed billet length; Volume balance residual. • Three guided experiments (Solid rod, Force-limited stall, Hollow profile), a built-in model verification check, a timestamped event log, a trial report and a short knowledge check.
R = billet area / exit area Ideal force = A₀ × mean flow stress × ln(R) Required force = ideal force × friction multiplier A₀ × ram displacement = exit area × output length One animation second = 2 process seconds.
Steady incompressible direct extrusion with constant mean flow stress and lumped friction. No die land resistance distribution, transient breakthrough peak, temperature evolution, elastic strain or tube seam integrity prediction. Dimensions, motion and process time are enlarged where stated for explanation. These are educational models, not machine programs or qualified production procedures.
Reduction in cross-sectional area. Volume is conserved as the billet becomes a smaller section.
No. Motion is gated by the available-force check.
