About this machine
This Demag ET Concept is a used injection moulding machine — sometimes referred to as an injection molding press — manufactured in 2004 and currently located in Germany. Injection moulding machines are used to produce plastic components by injecting molten material under high pressure into a closed mould, and they are found across industries including automotive, consumer goods, packaging, and electronics. Demag is a well-established German manufacturer with a long history of producing hydraulic and electric injection moulding machinery for industrial plastics processing.
The machine delivers a clamping force of 2,500 kN and a locking force of 2,750 kN, with a tie bar spacing of 630 × 630 mm (horizontal × vertical) and platen dimensions of 950 × 950 mm. The maximum daylight between platens is 1,505 mm, and the opening stroke is 675 mm. Mould height ranges from 330 to 830 mm, making the machine suitable for a broad variety of tool sizes. Mould weight capacity is 1,100 kg on the fixed side and 2,200 kg on the moving side, giving a total mould weight capacity of 3,300 kg.
The injection unit carries a screw diameter of 60 mm with a length-to-diameter ratio (L/D) of 20. Shot volume is 636 cm³ and maximum shot weight is 579 g. Injection pressure reaches 1,351 bar, and the plasticising rate is 74 g/s (measured on PS). Maximum dosing stroke is 225 mm and screw speed is 326 rpm. The nozzle has a radius of 15 mm and a bore diameter of 3 mm. A second injection unit is listed in the data but carries no specifications, and the machine is understood to be a single-component configuration.
The ejector has a stroke of 200 mm and a force of 80 kN, with a centering ring diameter of 200 mm. A pneumatic ejector is fitted, and two core pulls are present on the moving side. Valve gate control is hydraulic; pneumatic valve gate control is not equipped.
The machine is fitted with a Wittmann W633-961 linear robot with a vertical (Y) stroke of 1,600 mm, a horizontal (X) stroke of 900 mm, and a longitudinal (Z) stroke of 2,500 mm. Hot runner control covers 9 zones. Mould sensing is provided by a Kistler system configured for pressure measurement (p=1); temperature sensing (t=0) is not active. A printer interface is installed, and the machine is equipped with process control and statistical process control (SPC) functionality.
