About this machine

This Arburg 520S- is a used injection molding machine — sometimes referred to as an injection moulding press — manufactured in 2016 and currently located in Germany. Injection molding machines are used to produce plastic components by injecting molten material into a mould under high pressure, and are found across a wide range of industries including automotive, consumer goods, packaging, and medical manufacturing. Arburg is a well-established German manufacturer with a long history of building precision injection molding equipment, recognised globally for the quality and reliability of its machinery.

The machine was built in 2016 and has accumulated 9,171 operating hours. It delivers a clamping force of 1,600 kN, with a programmable and controlled build-up of that force through an extended clamping program featuring two stages. The hydraulic ejector on the moving platen is servo-controlled, allowing precise and repeatable part ejection.

The injection and plasticizing unit is built around a 45 mm screw diameter. It is constructed in a high wear-resistant version, incorporating a sinter-metal check ring and CrN coating applied to both the screw and the check ring. This configuration makes the machine well suited to processing abrasive, corrosive, and high-temperature thermoplastics, with cylinder heating capable of reaching up to 450 °C. Heating is distributed across six zones, each rated at 3.6 kW at 230 V / 16 A.

The hydraulic system operates at Technology Level 2, comprising a servo-controlled dual-circuit pump arrangement with two regulated hydraulic pumps that enable precise, simultaneous parallel movements. Nozzle contact force and holding pressure are both programmable, and the system benefits from continuous oil circulation supported by additional cooling and filtration.

Control is handled by the SELOGICA direct system, which features touchscreen operation with a process editor on a 15-inch (38.1 cm) display. The interface supports multiple languages including German, English, and a configurable local language. For connectivity, the machine is equipped with an OPC UA interface for MES or host computer integration, USB and CompactFlash interfaces for data storage, and a EUROMAP 67 robot interface. It is also mechanically and electrically prepared for integration with an ARBURG MULTILIFT robot system, though no robot or automation equipment is included with this listing.

Utilities on board include a pneumatic supply with pressure regulator and a cooling water distribution system with adjustable circuits and flow indicators. The machine operates on a 400 V / 50 Hz supply with neutral conductor.
