This KraussMaffei KM MX is a large-tonnage injection molding machine — sometimes referred to as an injection moulding press — designed for the processing of thermoplastic materials. Injection molding machines of this class form plastic parts by injecting molten material under high pressure into a closed mold, making them central to high-volume plastic component manufacturing across automotive, packaging, consumer goods, and industrial sectors. KraussMaffei is a well-established German manufacturer with a long history of building injection molding, extrusion, and reaction process machinery for demanding industrial applications worldwide.
This particular machine was built in 2012 and is offered used from a location in Poland. It is equipped with a complete plasticizing unit fitted with abrasion protection, making it suitable for processing filled or abrasive thermoplastic compounds.
The clamping unit delivers 13,000 kN of clamping force, supported by a mold opening force of 910 kN. The mounting platens measure 2,210 by 1,910 mm, with a tie bar spacing of 1,570 by 1,270 mm, accommodating large molds. The ejector stroke reaches 350 mm, with ejector force rated at 250 kN or 125 kN depending on configuration.
The injection unit is built around a 105 mm screw diameter and is capable of generating an injection pressure of 2,296 bar. Injection volume is 5,195 cm³, with a shot weight of 4,728 g referenced to polystyrene, and an injection rate of 856 cm³/s — figures that reflect the machine's capacity for large, complex parts or high-throughput production cycles.
Plasticizing performance is equally substantial. The screw operates at up to 103 or 145 rpm, delivering a plasticizing throughput of 122 g/s at standard speed, rising to 171 g/s at the higher speed option. The barrel features seven heating zones, with an installed heater power of 71 kW. The hydraulic system is driven by a pump motor rated at 132 kW, with an oil tank capacity of 2,440 litres. Dry cycle time, measured according to Euromap 6, is rated at 765 cycles per hour.
The machine has an installation footprint of 13.03 by 3.65 metres and stands 2.82 metres tall, with a net weight including the control cabinet of approximately 70 tonnes.
