This Arburg 420A is a used injection moulding machine — sometimes referred to as an injection moulding press — dating from 2007 and currently located in Germany. Injection moulding machines are used to produce plastic components by injecting molten material into a mould under pressure, and they are found across a wide range of manufacturing industries including automotive, consumer goods, medical devices, and packaging. Arburg is a well-established German manufacturer with a long history of building precision injection moulding equipment, and the company is widely recognised for its all-electric and hybrid machine platforms as well as its proprietary Selogica control technology.
The machine's main movements — dosing, injection, mould open and close, and ejector — are electromechanical, driven by servo motors. Nozzle displacement is handled hydraulically, supported by a small hydraulic unit with an accumulator and a 10 cm³ pump rated at 5.5 kW. The clamping unit uses a five-point double-toggle design with servo-electric adjustment and electric mould height adjustment. Mould protection is provided via ejector position monitoring. The machine platens are fitted with a centering ring of 125 mm diameter, and the fixed platen is mechanically prepared for mounting a linear robot. A quick-coupling system is included for the ejector bar, and an electric ejector with position control is fitted. A programmable hydraulic core is available for parallel movements.
The injection unit is a horizontal 400 unit with servo regulation and a programmable nozzle contact force. The plasticizing unit is modular, featuring central coupling and adaptive temperature control. The plasticizing assembly has a 25 mm diameter screw built for high wear and corrosion resistance. The nozzle configuration includes an open nozzle and a flat nozzle tip, with heater band heating capable of reaching up to 450 °C. A standard drive coupling with double-flat connection is fitted. The machine is configured for thermoplastic processing and is supplied without a hopper.
Machine cooling is regulated and programmable, with a water cooling manifold providing four manually adjustable circuits. A water shut-off valve is included. The electrical cabinet is temperature-regulated, and the control system is Selogica Direct. The interface suite is extensive: Euromap 65 and Euromap 67 robot interfaces are fitted, along with electrical and mechanical preparation for an external robot. Additional interfaces include connections for an HB-Therm mould temperature controller, a Thermolift dryer, and a colour dosing unit. A USB serial interface for a printer, a flash card reader, and operator authorisation by card are also present. The control system supports 12 mould temperature measurement zones and includes an additional heater band for the nozzle. An acoustic alarm and an additional socket combination with RCD are fitted.
Seven software packages are included covering extended mechanical cycle controls, extended movements, production control, optimisation and operator assistance, quality assurance control, and documentation. The control interface is configured in French. Additional equipment fitted to the machine includes a programmable electric conveyor belt and a sorting flap for separating good and bad parts.
