Used Arburg Allrounder 520 Injection Molding Machines for Sale 5

Arburg Allrounder 520 positioning

The 520 model designation indicates a 520-millimetre platen size, with proportionally scaled tonnage typically in the 150 to 170-tonne range depending on the specific configuration and tie bar spacing. The 520 sits between the 470 and the 570 in the Arburg lineup, addressing applications larger than the 470 but smaller than the 570. The platform is particularly common in automotive interior parts, larger consumer goods, household appliance components, and medium-format packaging across European processors.

520 drive variants

Key 520 sub-variants in European inventory follow the same drive-variant logic as the 470: the 520 C Comfort and 520 S hydraulic variants for general technical processing, the 520 H Hidrive hybrid for energy-efficient operation with maintained injection performance, and the 520 A Alldrive all-electric variant for high-precision and energy-conscious applications. The Edrive entry-electric variant is less common at this tonnage but exists in specific configurations.

520 shot weight and screw configurations

Shot weight capacity on the 520 series varies significantly with screw size: standard configurations carry screw diameters from 35 to 50 millimetres, addressing shot weights from approximately 100 grams up to over 700 grams in PS equivalent depending on screw size and L/D ratio. The screw and barrel selection at original purchase determines the practical shot weight envelope; multi-screw configurations are uncommon and require specific factory specification.

Application examples

Common 520 applications include automotive interior trim panels, larger consumer goods enclosures (small appliance housings, kitchen equipment), household appliance components (washing machine drum housings, dishwasher panels), industrial packaging crates and pails, and medium technical parts in carbon and reinforced engineering thermoplastics.

Selogica control

As with all Allrounder machines, the Selogica control is the defining element. Earlier 520 series units carry earlier Selogica versions; later units include the Selogica direct touchscreen and the Selogica ND (new design) interfaces. Operator familiarity with Selogica significantly affects the buy decision and the operator transition timeline for shops new to the platform.

Used 520 inspection priorities

Used 520 due diligence covers the standard inspection points for Arburg machines: screw and barrel condition, tie bar condition, platen parallelism, clamping system condition, and cycle count from the Selogica control. The hydraulic system on C, S, and H variants requires verification of pump pressure stability, valve operation, and oil cleanliness; the A variant requires verification of servo drive condition, ball-screw wear, and linear scale accuracy.

Used Allrounder 520 value drivers

Used Arburg Allrounder 520 machines benefit from continuing parts availability through Arburg's European service network, the wide Selogica operator pool, and the established trade in compatible hot runner systems and robots. The 520 platform's wide installed base ensures regular inventory turnover.

Browse used Arburg Allrounder 520 injection moulding machines on Exapro to compare 520 C, S, H, and A drive variants from verified sellers worldwide. When evaluating a used Allrounder 520, verify the cumulative cycle count and runtime hours from the Selogica control, inspect screw and barrel condition, check tie bar condition and platen parallelism, confirm hydraulic system pressure on C/S/H variants or servo drive condition on A variants, request the screw and barrel inspection report where available, and request any documented major service interventions.
