About this machine

This Arburg 520S- is a used hydraulic injection moulding machine — sometimes referred to as a plastic injection press — manufactured in 2016 and currently located in Germany. Injection moulding machines of this type are used to melt thermoplastic material and inject it under pressure into a closed mould, producing precision plastic components across industries including automotive, packaging, consumer goods, and medical technology. Arburg is a well-established German manufacturer with decades of experience producing injection moulding machinery, recognised for engineering quality and advanced control systems that serve demanding industrial applications.

The machine delivers a clamping force of 1,600 kN, with programmable and controlled build-up of that force and an extended clamping programme operating across two stages. The injection and plasticising unit is fitted with a 45 mm screw diameter and is specified 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 suitable for processing abrasive, corrosive, and high-temperature thermoplastics, with cylinder heating capable of reaching up to 450 °C. Barrel heating is distributed across six zones, each rated at 3.6 kW (230 V / 16 A). The ejector is servo-controlled and mounted on the moving platen.

Hydraulic performance is handled by a Technology Level 2 dual-circuit pump system comprising two regulated hydraulic pumps that enable precise, parallel movements. Nozzle contact force and holding pressure are both programmable, and the hydraulic circuit includes continuous oil circulation with additional cooling and filtration. 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.

Control is provided by Arburg's SELOGICA direct system, operated via a 15-inch (38.1 cm) touchscreen with a process editor. The interface supports multiple languages including German, English, and a configurable local language. For connectivity, the machine is equipped with an OPC UA interface suitable for MES or host computer integration, as well as USB and CompactFlash interfaces for data storage and programme transfer.

The machine is prepared for robot and automation integration via a EUROMAP 67 interface and has been made ready for fitment of an Arburg MULTILIFT robot system, though no robot or automation equipment is included with this listing. No additional equipment beyond the machine itself is offered.
