80-ton Aluminium cold chamber PDC Die casting machine

80-ton Aluminium cold chamber PDC Die casting machine

An 80-ton machine provides ~800 kN of clamping force to keep the die shut while molten aluminium is injected at high speed/pressure. “Cold chamber” means aluminium is melted in a separate furnace and ladled into the shot sleeve (aluminium is too corrosive/hot for hot-chamber systems)

  • Real-time shot control
  • Closed-loop hydraulics/servo
  • Robust tie-bar & platen design
  • Die temperature integration
  • Process monitoring
  • Quick die-change

1.Typical technical specs (vary by manufacturer)

  • Clamping force: ~800 kN (≈80 tons)

  • Die height (min–max): ~180–350 mm

  • Tie-bar spacing (H×V): ~300–350 mm × 300–350 mm

  • Platen size (H×V): ~500–600 mm × 500–600 mm

  • Injection system: plunger with 2-stage speed (slow shot for fill, fast shot for intensification)

  • Shot sleeve Ø: ~40–60 mm

  • Max shot stroke: ~200–250 mm

  • Theoretical shot volume: ~250–500 cm³ (useful aluminium shot weight ~0.7×volume)

  • Specific injection pressure: ~40–70 MPa (400–700 bar)

  • Ejector force/stroke: ~30–50 kN / 60–100 mm

  • Dry cycle time: ~2.0–2.5 s; Typical cycle time (Al): 25–45 s (part-/die-dependent)

  • Drive motor: ~15–30 kW; Hydraulic oil tank: ~200–350 L

2. Required auxiliaries

  • Melting/holding furnace (gas or electric) sized to your hourly throughput.

  • Ladle (manual, servo, or robot), die-spray system, extractor/robot.

  • Die thermoregulators (oil/water), chiller/cooling tower for hydraulics and die.

  • Trim press, shot-blasting, CNC/deburr, leak test (as needed).

  • Vacuum system if you need low-porosity or heat-treatable parts
