A plastic bottle manufacturer has slashed energy use by 60% and ramped up output by almost a third after installing a new technology.

Northern Irish firm PrimePac had been using a 23-year old blow molding machine to create its bottles – because it had spent its life running 24 hours a day, five days a week, its motor was operating inefficiently and slowly.

The time taken to create a bottle had extended from 10 seconds to 12 seconds and the amount of wastage had also risen.

The firm decided to install a 55kW ABB motor and an ACS880 drive to reduce electricity use, improve quality and consistency and free up electrical capacity to power a new injection molding machine.

The £7,400 purchase is expected to pay for itself in under a year – as a result of reduced waste, the granulator machine used for recycling is also used less, saving around 5% of the site’s energy.
