This Krauss Maffei C3 is a used injection moulding machine — sometimes referred to as an injection moulding press — manufactured in 2006 and currently located in Germany. Injection moulding machines are used to produce plastic parts and components by injecting molten material into a closed mould under high pressure, and are fundamental to industries ranging from automotive and packaging to consumer goods and technical engineering. Krauss Maffei is a well-established German manufacturer with a long history of producing plastics processing machinery, including injection moulding, extrusion, and reaction process technology, serving industries worldwide.
This is a hydraulic machine, and its closing unit is specified in detail. The platens measure 1,510 x 1,370 mm, with a distance between tie bars of 1,000 x 930 mm — the clear space through which the mould must pass and which determines the maximum mould footprint. The opening stroke is 1,150 mm, giving the distance the moving platen travels to open the mould, while the total open daylight reaches 1,750 mm. The minimum mould size is 600 mm and the ejector stroke is 250 mm, the latter governing how far finished parts can be pushed clear of the mould face.
The injection unit is designated SP 3500 and is fitted with an 80 mm screw diameter. The screw has an L/D ratio of 25.9, indicating a relatively long plasticising barrel well suited to thorough and consistent melt preparation. Injection pressure reaches 2,205 bar, and the volume stroke is 1,543 cm³. Maximum shot weight is quoted at 1,404 g for polystyrene, or approximately 1,110 g for polypropylene — a practical pair of reference values that reflect the density difference between the two common materials.
Installed power is substantial. The main hydraulic motor is rated at 160 kW, and a dedicated servo motor of 70 kW is fitted specifically for dosing, enabling parallel operations where plasticising can occur simultaneously with other machine movements. Heating power for the barrel and tooling zones amounts to 57 kW.
In terms of connectivity and auxiliary equipment, the machine includes one core valve and three air valves, and is equipped with an EU 12 interface for robot integration, allowing automation to be connected for part removal or insert loading. Platen and foundation drawings are available. The machine is reported to still be under power at time of listing.
