This Arburg 420A is a used injection molding machine — sometimes referred to as an injection moulding press — built in 2007 and currently located in Germany. Injection molding machines are used to manufacture plastic parts by injecting molten material into a mould under high pressure, and Arburg is a well-established German manufacturer with decades of experience producing precision plastics processing machinery for industries ranging from automotive and medical technology to consumer goods and packaging.
The machine's drive architecture combines electromechanical servo technology with a small hydraulic unit. The four primary movements — dosing, injection, mould open/close, and ejector — are all driven by servo motors, while nozzle displacement is handled hydraulically via a compact hydraulic unit equipped with an accumulator, a 5.5 kW motor, and a 10 cm³ pump. The machine platens feature a centering ring of 125 mm diameter.
The injection unit is a horizontal 400-series servo-controlled assembly. It incorporates a modular plasticizing unit with central coupling and adaptive temperature control. The plasticizing assembly uses a 25 mm diameter screw rated for high wear and corrosion resistance, and is fitted with an open nozzle and a flat nozzle tip. Heater bands are installed and rated for temperatures up to 450 °C. Nozzle contact force is servo-regulated and fully programmable. The machine is configured without a hopper.
The clamping unit uses a five-point double toggle design with servo-electric mould height adjustment, providing precise and repeatable clamping force control. The unit includes an electric ejector with position control, a quick coupling for the ejector bar, and mould protection via ejector position monitoring. A programmable hydraulic core is fitted for parallel movements. The fixed platen is mechanically and electrically prepared for the mounting of a linear robot, with a Euromap 67 robot interface also installed.
Cooling and temperature management are well specified. Machine cooling circuits are regulated and programmable, and a cooling water manifold with four manually adjustable circuits is included alongside a water shut-off valve. The machine supports 12 mould temperature measurement zones and includes an interface for an HB-Therm mould temperature controller. An additional heater band for the nozzle is fitted, and an interface for a Thermolift dryer is also present.
The control system is Arburg's Selogica platform, configured here with Selogica Direct and a French language interface. A substantial suite of software packages is installed, covering extended mechanical cycle controls, extended movements, production control, optimisation and operator assistance, quality assurance control, and documentation functions. Operator access is managed via card authorization to the Euromap 65 standard. The electrical cabinet is temperature-regulated and equipped with a flash card reader, USB serial interface for a printer, an acoustic alarm, and an additional socket combination with residual current device protection. Interfaces are also present for a color dosing unit.
Additional equipment supplied with the machine includes a programmable electric conveyor belt and a sorting flap for separating conforming parts from rejects, rounding out a capable and well-optioned production cell ready for thermoplastic processing.
