Installed at its Pudahuel production facility, both machines are producing lightweight PCO 1881 screw caps for the second-largest Coca-Cola bottler in Chile, helping to cut carbon emissions across the value chain and reduce carbon footprint by using less material.
With an annual production of more than one billion parts, Envases, the largest packaging producer in Chile, regards itself as one of the leading domestic PET processors.
Having entered into a joint venture with Coca-Cola Embonor in 2012, the plastics manufacturer continues to demonstrate its commitment to sustainable packaging.
Responding to market demands, Envases added a PCO 1881 closure to its extensive screw cap product portfolio. Aside from lowering plastics resin consumption, the lightweight closure is designed to protect the product quality of carbonated beverages.
As well as supplying the 96-cavity moulds, Canadian mould manufacturer StackTeck managed the planning of the entire line, including machinery, ancillary equipment, test and cooling systems as well as in-line inspection, part transfer, internal and external part decoration and boxing systems.
The two Sumitomo (SHI) Demag El-Exis SP injection moulding machines were central to the solution.
Specifically developed for the packaging market, the El-Exis SP range combines electric and hydraulic drives, offering maximum speed and dynamics resulting in higher output rates, whilst lowering energy consumption by up to 40%.
For the managers at both Envases and StackTeck, the Sumitomo (SHI) Demag moulding solution has been regarded as highly successful. “We were particularly impressed with how easily the machine integrated as part of the system. After millions of cycles our customer continues to be very happy with the performance and reliability,” Simon Martin, director closure systems at StackTeck pointed out.
