This Kraussmaffei KM125-520C2 is a used hydraulic injection molding machine — sometimes referred to as an injection moulding press — manufactured in 2003 and currently located in Germany. Injection molding machines are used to produce plastic components by injecting molten material into a mould under high pressure, and Kraussmaffei is a well-established German manufacturer with a long history of building precision plastics processing equipment for industries ranging from automotive and packaging to medical technology and consumer goods.
At the heart of the clamping unit, the machine delivers a clamping force of 1,250 kN, with an opening stroke of 900 mm and a tie bar spacing of 470 × 470 mm (horizontal × vertical). The minimum mould installation height is 300 mm, and the machine can accommodate moulds weighing up to 1,485 kg. The opening force is rated at 35 / 28 kN, the ejector stroke measures 150 mm, and the ejector force is 22 / 10 kN.
The injection unit is designated SP 520 and accepts three screw diameter options — 35, 40, and 45 mm — giving operators flexibility across different material volumes and part geometries. The corresponding shot volumes are approximately 156, 204, and 258 cm³ respectively. Injection pressure reaches approximately 1,800 bar or above depending on the screw selected, and screw speed is rated at approximately 391 or 489 rpm. The plasticizing rate with polystyrene (PS) ranges from approximately 22 to 41 g/s, again varying with the screw in use.
On the power side, the pump motor produces 18.5 kW, and the installed heating capacity is 13 kW. The machine operates on a three-phase power supply at 400 V and 50 Hz. The hydraulic system requires an oil filling quantity of 345 litres. A cooler is included with the machine as additional equipment.
