K 2019 Preview: Green's the Theme in Extrusion & Compounding

Themes of sustainability and the Circular Economy will be visible at the booths of many suppliers of extrusion and compounding equipment—film, in particular.

Under One Roof: Innovative Recycler Closes the Loop

rPlanet Earth looks to disrupt the plastics recycling industry by creating a truly sustainable, closed-loop system for recycling and reuse of post-consumer plastics, with reclaim, sheet extrusion, thermoforming and preform making all in the same plant.

rPlanet Earth Opens Vertically Integrated Recycling Plant In California

Among a range of reclaim and polymer processing systems in place at the Vernon plant are three Welex sheet lines supplied by Graham Engineering Corp. and equipped with EDI extrusion dies and BKG melt delivery components from Nordson Corp.

Making an Impact In Thin-Gauge Sheet

Creating a ‘virtually integrated supply chain’ that connects it with suppliers and customers has helped Impact Plastics add value to a wide range of sheet products, with a growing emphasis on PP.

Extrusion Veteran Jim Nissel Retires from Welex

James Nissel grew up in and around Welex since its inception in King of Prussia, Penn. in 1966.

EXTRUSION AND COMPOUNDING NPE: Flexibility, Speed and Quality

Extrusion processors need more—of everything—to compete. And suppliers responded in force in Orlando.

EXTRUSION AND COMPOUNDING AT NPE: The Word Is ‘More’

As in speed, power, quality, flexibility, layers, and efficiency. Those are the trends across all extrusion processes.

Extrusion/Compounding at K 2013: Having It All

Extrusion processors no longer need to chose among speed, quality, and flexibility, based on exhibits at K 2013.

K 2013 Preview: Extrusion, Compounding, Recycling

Across all extrusion technologies, expect to see new standards in speed, quality, flexibility, and efficiency in both energy and material usage.

IML Groundbreaker Adds Sheet Extrusion

In-house sheet production allows Tech II to vertically integrate to hasten product development, control costs.

Packaging Powerhouse Does It All

Materials formulation, cast and blown film extrusion, sheet extrusion, printing, and laminating come under one roof at this processor.

Extrusion & Compounding at NPE: Advances Push Efficiency Envelope

Blown film towers may have been scarce, but there was no shortage of new technology aimed at helping to make extrusion processors more profitable.

Extrusion & Compounding at NPE: More Output, More Flexibility, Less Energy

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.

Rolls and Cut Sheet

Whether producing mono- or multi-layer sheet, many sheet extrusion systems produce rolls of finished sheet, or stacks of sheet that has been cut-to-length.

Sheet Extrusion Line

A sheet extrusion line consists of an Extruder (single or twin screw), equipped with a Screen Changer and a Gear Pump, followed by a Static Mixer (sometimes feeding a Coextrusion Feedblock that is preceded by one or more additional extruders sets as described above), feeding a flat sheet die.

K Show Report: Nanos Are The Rage

Flat film and sheet toolmakers are focusing on technologies for nanolayer systems.

Industry & Technology News - December 2010

Novel TPE/Polyimide Medical Tubing Through a special manufacturing process, TPE tubing with one or more lumens is being extruded inside thermoset polyimide medical tubing.

EXTRUSION & COMPOUNDING: Five-Layer Film Structures Set to Supplant Three Layers?

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.

Extrusion at NPE 2003

NPE is typically a competitive display of the biggest, most dramatic equipment machine builders can muster.

On-Site: Green Business Is Good Business for Fabri-Kal

Learning to deal with the particular characteristics of PLA biopolymer has opened up a promising business in “green” plastics for thermoformer Fabri-Kal.

NPE 2009 Wrap-Up: New Machinery for Extrusion and Compounding

Extrusion machinery at the June NPE show in Chicago showed inventive ways to get more out of your floorspace and materials.

NPE News in Extrusion

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.

High-Speed Extrusion: Are You Ready for the Fast Lane?

Around three dozen, mostly European, processors are pushing commercial development of high-speed single-screw extrusion. They have installed more than 100 of the small hyper-drive machines whose screws turn at up to 1500 rpm, about eight to 10 times faster than standard extruders. At least two German machine builders are working on machines that will go to 2000 rpm and even higher. The goal is to raise output without increasing extruder size.

Investing in Planet-Friendly Packaging

Clear Lam Packaging Inc. is a mid-sized, family-owned packaging company with an enviable growth rate of over 20%/yr, unusual at a time when many mid-sized packaging companies are being bought out and disappearing. The secret, Clear Lam believes, has been its aggressive investment in R&D.

K 2007 Extrusion: Extrusion Outputs Go Through the Roof

Dramatic production demonstrations of cast and blown film set throughput records on the show floor in Dusseldorf.

What's New at the Show in EXTRUSION

It’s all about higher speeds and higher outputs at this year’s “K” show in Germany.

What to See at NPE 2006: Extrusion

The new factor in extrusion machinery at this NPE is the influx of Asian suppliers.

Extrusion (K 2001 Preview)
