Process avoids the need to cool PET after pelletizing and then reheat it for crystallization
Extrusion processors no longer need to chose among speed, quality, and flexibility, based on exhibits at K 2013.
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.
Blown film towers may have been scarce, but there was no shortage of new technology aimed at helping to make extrusion processors more profitable.
There will be an extraordinary range of new auxiliary equipment on display at the show.
There won't be many blown-film lines running, but there is still much in the way of innovation going on in extrusion and compounding.
Processing Technologies International (PTi), recently took the wraps off its “dryer-less” twin-screw PET sheet extrusion system at its headquarters in Aurora, Ill.
Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.
Extrusion machinery at the June NPE show in Chicago showed inventive ways to get more out of your floorspace and materials.
Compounding news at the show includes several new ways to feed low-bulk-density materials faster for higher outputs with corotating twin screws.
WEB EXCLUSIVE At least two suppliers will have new developments in melt filtration at the show next month in Chicago.
The first slide-plate screen changers from Kreyenborg GmbH in Germany (U.S. office in Lawrenceville, Ga.), were introduced last month.
That title is claimed for a Poly 6000x4 screen changer from Kreyenborg GmbH in Germany (U.S. office in Lawrenceville, Ga.), built for throughput of up to 100,000 lb/hr of PET.
The German parent of Kreyenborg Industries, Lawrenceville, Ga., has built a new device to maintain uniform flow to a die or pelletizer during backflushing of a screen changer.
A new low-cost approach restores the properties of recycled PET bottle flake to produce new food-grade preforms and pellets.
A new crystallizing pelletizer for PET pellets from BKG GmbH, a unit of Kreyenborg Group, Lawrenceville, Ga., has seen its fi rst two U.S. installations and four more are on order, all for PET resin producers.
NPE was full of new equipment and systems for recapturing valuable in-plant scrap and post-consumer/post-industrial plastic waste. Recovery of PET packaging and film or fiber waste were particular areas of emphasis, as were lots of new granulators, from the world’s biggest to micro-size and even ‘clean-room’ models.
