achieved a one second cycle time saving in comparison to a standard IntElect model.” He continued: “Fluctuating energy costs creates
uncertainty. Particularly for mass-manufacturers where energy is the highest and most unpredict- able expense. To counteract this, processing repeatability and reduced waste is imperative.” The exhibit also demonstrated the use of digital
product passes via R-Cycle. With this, every container provides dynamic data regarding the used material which can be easily accessed via a QR code label. The machine included a side-entry robot from automation specialist Campetella, which efficiently removed the lids from the mould tool, stacking them onto a conveyor belt. The four-cavity mould tool was supplied by Bazigos. Moulding material came from the Borealis Bornew- able portfolio.
Netherlands-based injection moulding machine
maker Stork IMM introduced its new generation of packaging machines at Fakuma. In the develop- ment of the updated range, the company said it focussed on stiffness and stability, sustainability needs and energy efficiency. “As wall thickness in packaging products
reduced over the years, mostly for economic reasons,” said Stork, “moulds and machines were redesigned heavier to withstand the higher cavity pressures that goes together with a thinner wall thickness. Stiffness and stability of the mould clamping and support have always been the most important parameters in thin walled packaging. We’ve therefore carefully fortified our machine, empowering it to effortlessly navigate the chal- lenges of today’s thinner walls and higher cavity pressures.” The benefits to the customer from higher mould
stiffness and stability include a longer lifetime of both mould and machine. Stork said the improve- ments elevate product quality while minimising maintenance costs. “Moreover, our innovative
design empowers you to operate at a lower clamping force, unlocking new levels of energy efficiency and cost savings. The stiffer the clamping unit, the more of the actual clamping force can be distributed to the mould instead of being con- sumed by the clamping unit itself,” it said. Addressing the shift to more sustainable
packaging, Stork noted the potential to make packaging re-usable, in which packaging could be redesigned with greater wall thickness. Nonethe- less, thin-wall packaging will continue to play an important role in sustainability. It said: “In some packaging products, where reuse is harder to achieve, wall thickness might even reduce further in order to reduce the use of plastics. By embracing thinner walls and pioneering new possibilities, we’re charting a course toward a more eco-friendly footprint. And let’s not overlook the remarkable potential of using R-PET for food packaging. The use of (R-)PET for packaging products will most definitely lead to considerable higher cavity pressures, demanding a higher stiffness and stability.” These developments were an important driver
for Stork to redesign its clamping unit. “Most importantly by changing the way that the high forces, caused by the significant cavity pressures during injection, are being diverted into the toggle mechanism. Furthermore, Stork IMM designed a broader linear mould support for an even more accurate mould alignment, ensuring impeccable precision, aligning perfectly with your needs,” said the company.
