This Krauss Maffei KM350/1900 C2 is an injection moulding machine — sometimes referred to as an injection moulding press — used to produce plastic components by injecting molten thermoplastic material under high pressure into a closed mould. Krauss Maffei is a well-established German manufacturer with a long history of producing injection moulding machinery, extrusion systems, and reaction process equipment for the plastics and rubber industries worldwide.
The machine was built in 2005 and is offered in used condition from a location in Germany. It is a fully hydraulic two-platen clamping system, delivering a clamping force of 3,500 kN and a mould opening force of 220 kN. The moving platen travel forces are 105 kN when opening and 95 kN when closing. The platen dimensions measure 1,060 × 1,095 mm (horizontal × vertical), with a clear daylight between tie bars of 710 × 710 mm. The mould opening stroke is 920 mm, giving a maximum opening width of 1,300 mm, and the minimum mould installation height is 380 mm. The maximum permissible mould weight is 4,780 kg. The ejector stroke is 250 mm, with ejector forces of 95 kN forward and 48 kN returning.
The injection unit carries a working capacity designation of 1900. It is fitted with a 70 mm diameter screw equipped with a non-return valve and open nozzle, the nozzle having a radius of 15.00 mm and a bore of 6.00 mm. Shot volume is 1,047 cm³, with a calculated shot weight for polystyrene of 953 g. Injection pressure reaches 1,778 bar, and the injection flow rate is 527 cm³/s. Standard screw speed is 285 rpm, with an optional extended speed of 349 rpm. The plasticising drive delivers 95 PS at standard speed and 117 PS at the optional higher stage. Nozzle contact force is 82 kN. The plasticising unit is described as a complete wear-resistant thermoplastic assembly. Pressure-volume (PV) control is fitted to the injection unit.
The pump motor is rated at 75 kW, and the installed heating capacity is 30 kW across six barrel heating zones. The machine runs at a dry cycle rate of 1,550 cycles per hour and holds 720 litres of hydraulic oil. Control is provided by an MC4 32-bit microprocessor system with an integrated operator panel featuring a TFT colour screen and a 3.5-inch floppy disk drive for data storage.
Overall dimensions are 6,510 × 2,040 × 2,380 mm (length × width × height), and the net weight including the control cabinet is approximately 16.0 tonnes.
