This Krauss Maffei CX is a used injection moulding machine — sometimes referred to as a plastic injection press — manufactured in 2010 and currently located in Germany. Injection moulding machines process thermoplastic and other polymer materials by melting and injecting them under high pressure into a closed mould, producing finished or near-finished components across industries including automotive, packaging, consumer goods, and technical parts. Krauss Maffei is a well-established German manufacturer with a long history of producing injection moulding, extrusion, and reaction process machinery, and its equipment is widely used in demanding industrial production environments.
The machine is equipped with a 90 mm screw diameter and an L/D ratio of 20, paired with a maximum stroke volume of 2,290 cm³ and a maximum shot weight of 2,084 g (PS), which positions it for medium-to-large part production. Injection pressure reaches 1,839 bar, and the plasticising rate is 185.8 g/s, supported by a screw speed of 270 rpm and a nozzle bore of 6 mm. The clamping force is 5,000 kN, reflecting a machine built for robust, high-tonnage work.
The clamping unit features an opening stroke of 1,170 mm and a maximum plate spacing of 1,650 mm. Mounting plates measure 1,270 × 1,200 mm (H × V), with clear column spacing of 900 mm horizontally and 800 mm vertically. The minimum tool installation height is 480 mm, and the centering ring diameter is 200 mm. The ejector delivers a force of 95.4 kN with a retraction force of 48.6 kN and a stroke of 250 mm; a pneumatic ejector is also fitted. Core pull control is provided via two connections on the operator side and two on the drive side, and two hydraulic closing nozzles are installed.
The machine runs on a Krauss Maffei MC5 control system and includes statistical process control (SPC) via a Kistler pressure sensor (p=2 / t=0). Connectivity is provided through a 12-port USB interface. Power is supplied by a 90 kW pump motor and 44 kW of heating power. The maximum crane load is rated at 10 tonnes. A KRC6-2 ARC-C linear robot is included, configured with X and Y axes as standard and a Z axis present. The machine is not configured for two-component (2K) moulding and does not include hot runner control or a filter nozzle.
