OPTIMISED ENERGY CONSUMPTION IN PET BOTTLE BLOW MOULDING
THE PRODUCTION OF POLYETHYLENE TEREPHTHALATE (PET) bottles can be carried out in two independent stages, whereby the preform injection and blowing are performed on machines that can be optimised separately. The preforms are positioned in a transport conveyor from an automatic feeder. Then preforms pass through a system of furnaces with IR lamps where they are softened and finally stretched and blown with high-pressure air into a mould. This is the technique used for the manufacture of bottles of water, soft drinks, juice, etc.
GREEN PACK is a project managed by UROLA, a cooperative that designs and creates solutions for the manufacture of containers using blow moulding technology, where GALBAIAN, a consultancy specialising in industrial property and the AZTERLAN Technology Centre, have also participated.
