For this lid maker, the keys to success are speed, flexibility and ingenuity.
Nordson Corp. continues to add to its portfolio of plastics equipment companies with the purchase of Kreyenborg GmbH, which makes screen changers; and sister company BKG Bruckmann, which makes pelletizers.
Nordson EDI, Chippewa Falls, Wis., has completely re-engineered its EPC edge-bead-reducing extrusion coating die, yielding a more robust system that is even easier to operate and cuts back substantially on downtime for width changes and cleaning, the company says.As in the past, the newest EPC die includes an external deckle as a secondary seal to prevent leakage and an internal deckle system that sets coat width and seals polymer at the die exit.
In a span of two weeks last month, Nordson Corp. spent $400 million to expand its interests in plastics.
Blown film towers may have been scarce, but there was no shortage of new technology aimed at helping to make extrusion processors more profitable.
Last month bought three changes of significance among equipment suppliers of extruded film and sheet.•Gloucester Engineering Co., Gloucester Mass., announced it had acquired Future Design Inc., Mississauga, Ont.
Processing Technologies International (PTi), recently took the wraps off its “dryer-less” twin-screw PET sheet extrusion system at its headquarters in Aurora, Ill.
They call it the “The Beast,” a new sheet line installed recently by custom extruder Rowmark in Findlay, Ohio (rowmarkllc.com). It’s nearly as long as the new 175 x 75 ft facility built to house it.
New technology to process nano blown films unveiled by Dow at Antec. Nano cast film, sheet advances too.
Cleaning flat dies; injecting hollow parts.
Flat film and sheet toolmakers are focusing on technologies for nanolayer systems.
A new-generation feedblock for flat-die coextrusion simplifi es fine-tuning of layer thicknesses, reducing downtime.
Sheet processors know that the key to productivity is maximum extruder uptime.
In blown film, equipment and material suppliers have come together to push five-layer technology into non-barrier applications previously held by three-layer films.
In most segments of extrusion technology, the word at K 2010 is more.
A new die system for extruded PS foam board from Extrusion Dies Industries (EDI), Chippewa Falls, Wis., is said to dramatically reduce downtime for product changeovers, enhance control over product dimensions, reduce scrap, and eliminate shutdowns for die maintenance.EDI says the new XPS foam board die technology makes it possible to accomplish a product changeover on the fly in only 15 min, vs. the usual 8-10 hr.The added uptime offsets most of the output loss imposed by the switch to HFC blowing agents, EDI says.Key features include a separate, independently adjusted forming box that makes possible product changeovers without stopping the production line; and an adjustable, full-manifold internal deckle that can be used to modify both the width and thickness of the board.Foam board processor DiversiFoam Products reports that by using the new EDI system at its Rockford, Minn., plant, it has virtually eliminated downtime for scheduled thickness setups, making it possible to produce 11% more saleable product.(715) 726-1201 • extrusiondies.com Extrusion Dies, Inc. 911 Kurth Rd.
Extrusion machinery at the June NPE show in Chicago showed inventive ways to get more out of your floorspace and materials.
This NPE show won’t have a lot of extruders on the floor, either running or static. Instead, look for videos and announcements of new technology. You will also find lots of ingenious peripheral devices to improve output and quality and save resin. Some will do all three, and cost less into the bargain.
Injection MoldingHybrid Press Has Electric ClampNew injection presses that combine servo-electric and hydraulic movements to achieve high performance with energy efficiency will be discussed by Arburg Inc., Newington, Conn.
Last year, Extrusion Dies Industries, LLC in Chippewa Falls, Wis., bought Quality Machine of Chippewa Falls Inc., a reconditioner of blown film dies.
