New models of blow molding machines at the show were dominated by wheel machines and stretch-blow systems.
Growing use of electric drives in blow molding machinery gathered steam at the K 2010 show, as suppliers rolled out new all-electric and hybrid models for extrusion blow, injection-blow, and stretch-blow production.
Several new developments include a brand-new compression blow process, the first foamed PET bottles, and a preform decontamination approach for aseptically filled products sold at ambient temperature. Attendees also saw a new stack-mold Multi-Parting Line concept that doubles bottle output within the same machine footprint. (Additional NPE blow molding news appeared in May and June—see Learn More box.)
A new in-line inspection device called PETView from Krones Inc., Franklin, Wis., monitors the quality of blow molded PET containers before they exit the machine, and any defects are immediately transmitted to a closed-loop temperature controller for correction.
Development of all-electric and hybrid-electric blow molding machines may be gaining momentum, as evidenced by several new models introduced in Dusseldorf.
Improved clarity and cost competitiveness, added to its inherent heat resistance, are reviving OPP’s prospects in hot-fill barrier containers. But hot-fill PET containers are raising the bar with higher productivity and ‘panel-less’ bottle designs.
There will be a strong emphasis on energy savings in blow molding machinery at K 2007.
A new two-stage rotary stretch-blow machine from Krones Inc., Franklin, Wis., offers higher output in a compact machine footprint for production of PET bottles up to 1.5 liters.
Among the more unusual blow molding developments at K 2004 was a closed-loop control system that monitors and corrects material distribution in PET containers as they are produced.
No Breakthrough in Beer, But Juice & Soda Surge Ahead
The emphasis in blow molding equipment introductions at NPE 2003 is on higher output capability and greater versatility to take on emerging markets.
Energy efficiency and production cost savings were dominant themes of the blow molding exhibits at K 2001. A handful of new all-electric machines aroused intense interest, though they are aimed primarily at niche markets. And in two-stage (reheat) PET stretch-blow molding, the focus was on boosting output per cavity.
One cluster of blow molding innovations on display at K 2001 will address the need for more versatile single-stage injection stretch-blow molding (ISBM) machines. A thirst for energy savings underlies plans to launch all-electric units for PET and HDPE containers. Also in the limelight are advances in large-part technical blow molding.
Three hundred billion beer bottles a year worldwide is a mighty tempting target for the plastics industry. So it’s no surprise that 13 of 24 papers focused on beer packaging at the recent Nova-Pack Europe ’99 Conference, held in Germany by Schotland Business Research, Skillman, N.J.
