About this machine

This Arburg 520S- is a used hydraulic injection moulding machine — also commonly referred to as an injection molding press — manufactured in 2016 and currently located in Germany. Injection moulding machines of this type are used to produce plastic components by injecting molten thermoplastic material into a closed mould under high pressure, making them central equipment in automotive, consumer goods, medical, and general plastics manufacturing. Arburg is a well-established German manufacturer with a long-standing reputation for precision injection moulding technology, serving a wide range of industrial sectors worldwide.

The machine delivers a clamping force of 1,600 kN and is fitted with a 45 mm screw diameter. Its hydraulic system operates at a technology level described as servo-controlled with a dual-circuit pump arrangement, comprising two regulated hydraulic pumps that enable precise and parallel movements. Clamping force build-up is programmable, and an extended two-stage clamping programme is included. The ejector on the moving platen is servo-controlled, adding further precision to part ejection.

For demanding material applications, the injection unit is specified in a high wear-resistant version, incorporating a sinter-metal check ring and CrN (chromium nitride) coating on both the screw and check ring. These features make the machine suitable for processing abrasive, corrosive, and high-temperature thermoplastics. Cylinder heating reaches up to 450 °C, and heating zones one through six are each rated at 3.6 kW (230 V / 16 A). Nozzle contact force and holding pressure are both programmable. Continuous oil circulation is maintained with additional cooling and filtration provisions.

The machine is controlled via Arburg's SELOGICA direct control system, featuring a touchscreen process editor on a 15-inch (38.1 cm) display. The interface supports multiple languages including German, English, and a configurable local language. Connectivity is provided through an OPC UA interface for MES and host computer integration, along with USB and CompactFlash ports for data storage. The electrical supply is 400 V / 50 Hz with a neutral conductor.

Automation readiness is provided by a EUROMAP 67 robot interface, and the machine is prepared for integration with an Arburg Multilift robot system. Supporting utilities include a pneumatic supply with pressure regulator and a cooling water distribution system with adjustable circuits and flow indicators. No additional equipment is included with this listing.
