Used KRAUSS-MAFFEI KM 500-4300 CX | HORIZONTAL INJECTION MOULDING MACHINES

1. Clamping & Tooling (U.S. Standard)
Clamping Force: 5,000 kN (Approx. 562 U.S. Tons)

Tie Bar Spacing (HxV): 35.4" x 31.5" (Wider mold-fixing platen configuration)

Platens: Extended horizontal spacing with SPI-pattern threaded holes.

Core Pulls: Hydraulic system (1-fold) on the moving platen (non-operator side) equipped with twin check valves to maintain pressure.

Ejector System: Hydraulically actuated plate with fine-adjustment return speed and back-position limit switch monitoring.

Robot Interface: Mechanical interface (Euromap 18) on fixed platen + Euromap 67 signal interface.

2. Injection & Plasticizing (D90 Unit)

Screw Diameter: 3.54" (90 mm)

Screw Design: 3-flight non-return valve (RSP) with an open nozzle (US design).

Performance: Equipped with a pressure accumulator for increased injection capacity.

Control: PV closed-loop control with independent core pull/ejector movements during cycles.

Processing: Specially controlled back pressure for rigid PVC processing.

3. Hydraulics & Cooling

Filtration: ARGO external bypass oil filtration system with dedicated shut-off valves.

Monitoring: Oil drip tray level sensor for leak detection.

Cooling System: Upgraded oil cooler (Max 96.8°F water intake) with NPT water connections.

Pressure Gauges: Operator-side hydraulic selector switch pressure gauge.

4. Electrical, Control & Safety
