This Krauss Maffei KM125-520C2 is a used hydraulic injection moulding machine — sometimes referred to as a plastic injection press — dating from 2003 and currently located in Germany. Injection moulding machines of this type are used to produce plastic components by injecting molten material into a closed mould under high pressure, and are fundamental to manufacturing across the automotive, consumer goods, packaging, and electronics industries. Krauss Maffei is a well-established German manufacturer with a long-standing reputation in plastics processing machinery, supplying injection moulding, extrusion, and reaction process equipment to industrial customers worldwide.
The machine delivers a clamping force of 1,250 kN, with an opening stroke of 900 mm and an opening force of 35 / 28 kN. The tie bar spacing measures 470 × 470 mm (horizontal × vertical), and the minimum mould installation height is 300 mm. A maximum mould weight of 1,485 kg is supported. The ejector provides a stroke of 150 mm and an ejector force of 22 / 10 kN.
The injection unit is designated SP 520 and accommodates three screw diameter options — 35 mm, 40 mm, and 45 mm — giving the operator flexibility to match the screw to the material and part requirements. Corresponding shot volumes are approximately 156 cm³, 204 cm³, and 258 cm³ respectively. Injection pressure reaches up to approximately 1,800 bar or above depending on the screw selected, and screw speeds of approximately 391 or 489 rpm are available. Plasticising rate for polystyrene ranges from approximately 22 to 41 g/s, again varying with screw diameter.
Power is supplied via a three-phase 400 V connection. The pump motor has a rated output of 18.5 kW, and the installed heating capacity is 13 kW. The hydraulic system requires an oil filling quantity of 345 litres. A cooler unit is included with the machine as additional equipment.
