Sumitomo packaging collection to cater to UK sector growth 16 March 2023 × Comprising the new concept PAC-E, an El-Exis SP Servo range, plus a new IntElect S, the new collection gives manufacturers of caps, closures, thin-walled and high performance moulded containers a fusion of technology, productivity and energy-enhancing features. Rolling out to UK packaging converters and moulding firms during 2023, the expanded range reinforces the Group’s wider commitment to the circular packaging agenda and its delivery of sustainable value aligned to the key packaging market trends. Worth an estimated £4.6bn this year, and anticipated to grow by 4.2% in 2023, the UK Plastics Packaging Goods Manufacturing industry is anticipated to return to growth, underpinned by ongoing product innovation in flexible packaging. Indicative of the importance of the packaging market, Sumitomo (SHI) Demag revealed one of the most exciting developments in the last decade – the blend of its high-speed El-Exis packaging platform with the company’s IntElect all-electric series. PAC-E features a new injection unit specifically developed for high speed packaging applications. 72 caps every 1.98 seconds Two features differentiate PAC-E from the company’s El-Exis hybrid packaging series. The electric-driven axes deliver up to 50 percent in energy savings when measured against a high-speed hybrid packaging machine. Additionally, the lubrication of the toggle lever no longer causes cleanliness issues; being a completely closed circuit design it is leak free. Oil is instead extracted, filtered and recycled. This eliminates the need to clean the toggle lever. With injection speed capabilities of up to 550 mm/s, the PAC-E packaging machine will initially be available in mid-tonnage clamping forces of 250 tons, 300 tons, 350 tons and 420 tons. Designed for thin-walled packaging applications. Ultra-speed Servo In another advancement of the El-Exis SP, Sumitomo (SHI) Demag also presents its new ‘servo pump’ variant. UK Packaging Expert, Ashlee Gough, said: “With hybrid machines, the pump that charges the accumulator consumes approximately 50 percent of the overall energy used to power every injection cycle. By replacing the conventional pump with a servo pump, we can now maintain the same performance but consume significantly less power." Initially, the El-Exis SP Servo series will be expanded in the medium clamping force range, comprising  250 to 420 tons. Larger clamp force machines will subsequently follow. Fast-cycling for high-volume The release of an IntElect S all-electric mid clamp force range now means moulders requiring cycle time speeds of between three to 12 seconds don’t need to compromise on any aspect of productivity, energy efficiency and processing speed and stability. By expanding the IntElect S series, Sumitomo (SHI) Demag has now opened up the associated benefits of the all-electric moulding machine market to even more product applications. Positioned squarely between the conventional IntElect all-electric series and the new high-speed packaging injection moulding machine PAC-E, the IntElect S is geared specifically towards plastic processors mass-manufacturing narrow tolerance and thin-walled components. “Cycle times of between three and twelve seconds and injection speeds of up to 350 mm/s are the typical range of this machine," reports Gough. He draws special attention to the resilient, high performance drives, shorter clamp spindles and longer service life. Culminating in faster acceleration of the injection speed to achieve on average a one second cycle time saving when compared to a standard IntElect model. Benchmarking dry cycle times on thin wall packaging products with equivalent electric systems on the market, the IntElect S remains at the forefront of innovation and energy efficiency, assures Gough. All three ranges within the Group’s expansive ‘precision and speed’ packaging portfolio are designed to incorporate future digital product passport technology. Ensuring detailed transparency on machinery performance and the measurement of carbon footprints.
