About this machine

This Arburg Allrounder 920S is a hydraulic injection moulding machine — sometimes referred to as a plastic injection press — manufactured in 2007 and currently located in Germany. Injection moulding machines of this type are used to produce plastic components by injecting molten material into a mould under high pressure, making them central to high-volume manufacturing across the automotive, packaging, consumer goods, and industrial components sectors. Arburg is a well-established German manufacturer with a long-standing reputation for precision injection moulding equipment, serving production environments that demand reliability and tight process control.

At the heart of the machine's clamping system is a maximum clamping force of 5,000 kN. The opening stroke reaches up to 900 mm, with a maximum mould opening force of 150 kN and an enhanced opening force of 100 / 1,000 kN. Mould height is accommodated between a minimum of 400 mm and a maximum of 1,050 mm, with a distance between platens ranging from 1,300 to 1,950 mm. The tie-bar spacing is 920 × 920 mm horizontally and vertically, and the platen size is 1,280 × 1,280 mm. The movable platen carries a maximum half-weight of 8,000 kg. The ejector system delivers a maximum force of 800 kN over a stroke of up to 250 mm.

The injection unit is configurable with three screw diameters — 70, 80, and 90 mm — each carrying a different effective screw length expressed as an L/D ratio of 23, 20, and 18 respectively. Maximum shot volumes across these configurations are 1,232, 1,608, and 2,036 cm³, corresponding to maximum shot weights in polystyrene of 1,125, 1,469, and 1,860 g. Plasticising capacity in PS reaches 185, 215, and 250 kg/h depending on screw size. Maximum injection pressures are 2,500, 2,000, and 1,580 bar, while injection rates without the accumulator are 290, 380, and 482 cm³/s; with the accumulator engaged these rise substantially to 1,188, 1,552, and 1,964 cm³/s. Holding pressure is rated at a maximum of 350 or 200 bar depending on configuration, and screw speeds are 47, 54, and 61 rpm respectively. Screw torque is a consistent 3,500 Nm across all three diameters.

The nozzle contact force reaches a maximum of 110 kN, and the nozzle stroke extends to 675 mm. Barrel heating is provided by six zones of 5,500 W plus one zone of 4,300 W, with an additional 1,100 W of installed nozzle heating power. The hydraulic pump motor is rated at 75 kW, and total installed power stands at 96 kW. The machine draws on an oil fill volume of 590 litres and is protected by a motor and heating fuse combination rated at 200 A, with a dedicated heating fuse of 63 A. The control cabinet conforms to the DIN EN 60204 safety standard, and socket provision includes one Schuko and one CEE outlet. Dry cycle time for a 5 mm opening stroke falls between 4.5 and 6.44 seconds. This is a used machine offered in Germany.
