New machines are mostly all-electric, hybrid, or servo-hydraulic.
All-electric machines of all types were the stars of the show, but there were a number of other noteworthy developments.
Of the six machine builders who were willing to pull back the curtain even a little, five of them said they’d be showcasing all-electric presses. That remarkable fact suggests that all-electric technology, which has been a much harder sell in blow molding than in injection molding, is at last starting to find traction.
New models of blow molding machines at the show were dominated by wheel machines and stretch-blow systems.
After years of talk, all-electric blow molding machines seem poised to make advances.
Wheel machines in particular will be on display.
Higher throughputs and greater energy efficiency will be two big themes in blow molding at next month’s K 2010 show.
Already a familiar sight on European store shelves, the eye-catching appeal of "IML" is gaining traction among North American injection molders. The latest tooling and automation designs can handle the higher volumes needed here.
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.)
While occupying a relatively small category of exhibits, blow molding will present no lack of innovation at NPE.
Innovative bag-in-the-bottle technology from Gaplast GmbH of Saulgrub-Altenau, Germany, uses coextrusion blow molding to produce a thin bag made of ionomer inside a PP bottle.
Development of all-electric and hybrid-electric blow molding machines may be gaining momentum, as evidenced by several new models introduced in Dusseldorf.
Clear handled bottles got a kick start earlier this year when nationally recognized Simply Orange Juice Co., Apopka, Fla., an affiliate of the Minute Maid division of The Coca-Cola Co., decided to bottle its orange juice in extrusion blow molded 89-oz copolyester containers.
Show-goers will see a range of new blow molding equipment that offers higher speeds, more cavitation, and faster changeovers.
A new in-machine spin trimmer developed by M.C.
Improving productivity while minimizing capital cost and floorspace will be central themes of blow molding exhibits at NPE 2006.
Coex blow molding has the inside track, but makers of small gas tanks and jerry cans are also looking at fluorination and other monolayer systems. Rotomolders, too, are considering multilayer alternatives.
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.
One of the most interesting innovations in blow molding at K 2004 will be a top-and-bottom blowing system that is said to double bottle output.
Maybe this time the often-predicted breakthrough will actually occur. What could make the difference are improved resins, clarifiers, and machinery.
