Sumitomo (SHI) Demag Plastics Machinery GmbH, based in Schwaig, Germany, is continuing to improve the energy balance of its El-Exis SP series, one of the fastest packaging injection moulding machines on the market.
The European packaging market is expected to grow by 1.9 % annually between 2018 and 2023. However, the continued pressure to reduce the environmental impact of single-use plastic packaging along the supply chain is driving brand owners, retailers, packaging manufacturers and consumers alike to more sustainable measures to.
With an up to 20% lower energy consumption, compared to the predecessor models, Sumitomo (SHI) Demag is launching two energy-optimised El-Exis SP machines to the K-2019 - a large and a smaller version. The extremely high speed range, which is specifically geared towards the packaging markets, ensures that processors do not have to compromise on production efficiency, quality and sustainability.
The El-Exis SP series is now in its fourth generation.
„Still the fastest injection moulding machine in the world“,
Arnaud Nomblot, Head of Business Development Packaging at Sumitomo (SHI) Demag„The machines in the latest series are able to realise the shortest drying cycle times and are characterised by high process consistency and energy efficiency“

The hydraulic accumulator, which realises injection speeds of up to 1000 mm/s, is of central importance for the machine's short cycle time. This allows processors to produce even thinner packaging items. The series is also one of the fastest machines on the market in terms of injection dynamics.
„The combination of speed and high repeat accuracy in shaping helps to minimise waste in packaging production“
Arnaud Nomblot, Head of Business Development Packaging at Sumitomo (SHI) Demag
A new control valve has also been introduced for the El-Exis SP series. Thanks to the special regulation of the hydraulic pressure during the loading of the accumulator, the machines now consume up to 20% less energy than the previous models. The amount of energy saved depends on the packaging application, the cycle time and the process parameters.

Reducing energy consumption not only protects the environment, but also significantly improves the total cost of ownership (TCO) and return on investment (ROI) for packaging manufacturers. Centralised monitoring of machine performance and energy consumption in real time is also crucial for reducing machine downtime.
Mould labelling (IML) as well as multi-component injection moulding for premium packaging, bucket production with handle assembly and injection embossing remain part of the optional equipment scope of the El-Exis SP.
In a live demonstration at K-2019, Sumitomo (SHI) Demag will be converting a 72-cavity mould on an El-Exis SP 130,000 water bottle caps per hour produce.
„The El-Exis SP series is aimed directly at high-volume manufacturers of plastic products, such as caps and closures or thin-walled containers and lids, and offers better process control as well as lower operating costs and energy savings“
Arnaud Nomblot, Head of Business Development Packaging at Sumitomo (SHI) Demag
The El-Exis SP is available in a clamping force range from 150 to 800 tonnes.
