This Demag Concept 420 81 is a used injection moulding machine — sometimes referred to as an injection moulding press — manufactured in Germany in 2006. Injection moulding machines are used to produce plastic components by injecting molten material into a mould under high pressure, making them a cornerstone of plastic parts manufacturing across automotive, consumer goods, packaging, and industrial sectors. Demag is a well-established name in plastics processing machinery, with a long history of producing injection moulding equipment known for precision and process reliability.
The machine is identified by the seller as the Concept 420/ model and is equipped with an Ergo control unit, which handles process management and parameter setting during production cycles. The clamping force is 4,200 kN, a key indicator of the machine's capacity to hold moulds closed against the force of injection. The distance between tie bars measures 800 × 710 mm, and the mould platen size is 1,200 × 1,100 mm, giving a clear picture of the mould sizes this machine can accommodate. The maximum opening stroke is 710 mm.
On the injection side, the machine has a screw diameter of 60 mm and a stroke volume of 891 cm³, with an injection pressure of 2,420 bar. Shot weight is quoted at 800 g per polystyrene equivalent in the seller's notes, with a maximum shot weight of 1,090 g also stated. A 70 mm screw diameter is additionally listed in the technical data, suggesting the machine may be configurable with alternative screw assemblies.
The machine is located in Germany and is offered in used condition.
