Follow a reciprocating-screw barrel into a two-part mold. Watch the cavity fill and the clamp oppose projected injection force, then observe cooling and ejection or a modeled short shot.
• A 3D process cutaway of a reciprocating-screw barrel, mold clamp force, short shots and cooling, with labeled components you can select. • Controls: Available shot volume (60-120 cm³), Injection flow (20-60 cm³/s), Cavity pressure (20-100 MPa), Clamp force (100-600 kN), Cooling dwell (3-12 s). • Live readouts: Cavity volume filled; Mold separating force; Clamp force margin; Illustrative part temperature; Short-shot indicator; Clamp-overload indicator. • Three guided experiments (Insufficient shot, Clamp overload, Longer cooling), a built-in model verification check, a timestamped event log, a trial report and a short knowledge check.
Separating force = pressure(MPa) × projected area(mm²) / 1000 Projected area = 5000 mm²; cavity volume = 100 cm³ Delivered fill = min(shot,100)/100 Clamp margin = clamp force − separating force.
Prescribed clamp/fill/hold/cool/open/eject sequence with a prepared shot. Temperature decays toward 30 °C during cooling with a 4 s time constant from 220 °C. No rheology, packing shrinkage, solidification gate freeze, actual flash volume or ejection-temperature qualification. Dimensions, motion and process time are enlarged where stated for explanation. These are educational models, not machine programs or qualified production procedures.
No, force also depends on projected area. Pressure × projected area gives the separating-force estimate.
No. A short shot is a volume deficit.
