Thinking big
Lux: ALLROUNDER 1120 H produces mudguards
Large machine for large parts – this is a simple way to describe the purchase of its first ALLROUNDER 1120 H by automotive parts manufacturer Lux Kft. in Kecskemét, Hungary. Lux has been an ARBURG customer since 2010 and has been won over by the largest ARBURG machine and its features across various series and sizes.
Over the past three decades, Lux has produced around one million lift-and-slide roofs for motor vehicles, and since 2000 also a wide variety of windows for trailers, caravans, horse transporters and buses. In total, more than 400 plastic parts are produced in Kecskemét, including items made of fibre-reinforced plastics or with metal inserts, such as twist locks for trailer couplings and support wheels for trailers.
The moulded parts are assembled downstream both in automated and manual processes and imprinted using pad printing systems.
Digitalisation on the rise
The parts are also marked with a QR code using laser marking and undergo camera-supported visual quality inspections. A 3D printer is also used in the engineering area to create prototypes and to test whether it is possible to substitute metal components with plastics, among other things. So this is a production process that is being increasingly automated and operated using recyclates. Sunplast Kft., a Lux subsidiary, processes up to 800 tonnes of recycled material per year from PP, PE, PA and also soft PVC for reuse in the injection moulding process.
The company has set itself the goal of digital transformation. Many of the ALLROUNDERs are equipped with an OPC/UA connection. As a part of this, Lux also received the “Qualification in advanced level of prepared business for digitalisation (eDFV)” in 2021.
The owners of Lux saw the ALLROUNDER 1120 H for the first time at its world premiere at K 2016 and were immediately positive about the largest ARBURG machine and its features. This, together with their good experience of the other ARBURG machines and the support and after-sales services provided by ARBURG in Hungary, led to the purchase of the system and its integration into production at Lux.
Nicknamed “Optimus”
Since 2021, the ALLROUNDER 1120 H with 6,500 kN clamping force and size 4,600 injection unit has been part of the machine fleet. Nicknamed “Optimus” within the company, it produces mudguards for trailers with a 2-cavity mould. The goal of injecting just under two kilograms of PP was achieved with a screw that was extended by 100 millimetres. A linear MULTILIFT V robotic system is used for removal and deposit. After being placed on the conveyor belt, the relatively thin-walled mudguards are separated from the sprues with high precision using a cutting device and feed system, after which they are removed from the conveyor belt, finished and packaged.
1120 H meets all expectations
Pál Király, owner and managing director of Lux Kft., says of his experience with the large machine: “The impressions we now have of the ALLROUNDER 1120 H in our daily work are extremely positive. The machine is simple to operate, easily accessible, and works efficiently and reliably.” These are ideal conditions for further cooperation between Lux and ARBURG – including in new areas such as e-mobility.
