Packaging | thin wall moulding Reich highlights the folding PP IML-decorated fruit
baskets produced by Arburg on a hybrid 370-tonne Allrounder 820 H at Fakuma last year as evidence of the potential performance gains. The baskets were manufactured in a cycle time of around 5.8s, which Reich says is around 11% faster than using conventional hydraulic technology. The mould was built by SCS Società Costruzione Stampi, while an automation solution from Italian robotics specialist Campetella handled the feed and insertion of the two IML labels from Vertstraete into the mould and removed the finished parts.
Breaking speed limits Also at Fakuma, Sumitomo (SHI) Demag showed an El-Exis SP200 unit producing 125-mL polypropylene gourmet food containers in a cycle time of under two seconds (including robotic part removal from the four-cavity mould). Brink provided the mould and automation and Borealis the PP resin. The containers weighed 3.4g each and had a wall-thickness of 0.32 mm; the flow path/wall-thickness ratio was 213. Nigel Flowers, managing director of Sumitomo (SHI)
Demag’s UK operation, says the trend for “wafer-thin” food packaging is set to stay. “Given that the average European discards 159kg of packaging material each year, sustainability is an ongoing concern with a strong commercial incentive to do more with less,” he says. In mid-2015, the company’s IntElect all-electric
high-precision machines were equipped with a range of new standard features, which were unveiled at Fakuma. These are said to improve the machine’s usability both in operation and during mould changes. Injection
