About this machine
This Demag ET is a used hydraulic injection molding machine — sometimes referred to as an injection moulding press — manufactured in 2004 and currently located in Germany. Injection molding machines are used to produce plastic parts by injecting molten material into a mold under high pressure, and they are central to industries ranging from automotive and packaging to consumer goods and technical components. Demag is a well-established German manufacturer with a long history of producing precision injection molding equipment known for its reliability and engineering quality.
The clamping unit is built around a locking force of 2,750 kN, with tie bar spacing of 630 × 630 mm (horizontal × vertical) and platen dimensions of 950 × 950 mm. The machine accommodates mold heights between 330 and 830 mm, with an opening stroke of 675 mm and a maximum daylight between platens of 1,505 mm. Mold weight capacity is substantial: 1,100 kg on the fixed side and 2,200 kg on the moving side, for a combined total of 3,300 kg. The ejector delivers a force of 80 kN over a stroke of 200 mm and is also equipped with a pneumatic ejector function. A centering ring diameter of 200 mm is fitted, and the moving side carries two core pulls.
The injection unit carries a size designation of 840 and is fitted with a 60 mm screw running at an L/D ratio of 20. Shot volume is 636 cm³, and the unit develops an injection pressure of 1,351 bar. The plasticizing rate for PS material is rated at 74 g/s, with a maximum screw speed of 326 rpm and a maximum dosing stroke of 225 mm. The nozzle has a radius of 15 mm and a bore diameter of 3 mm. Based on the available data, this is configured as a single-component machine.
Additional equipment included with the machine is extensive. A Wittmann W633-961 linear robot is integrated for part handling, with a vertical Y-axis stroke of 1,600 mm, an X-axis stroke of 900 mm, and a Z-axis stroke of 2,500 mm. Hot runner control covers 9 zones, and a Kistler cavity pressure sensing system is installed for process monitoring. Valve gate control is hydraulic. On the controls side, the machine features a printer interface and statistical process control (SPC) capability.
