Once a year, we extrusionistas have a technical-commercial get-together somewhere east of the Mississippi. This year the venue was in Rosemont, IL, near O’Hare airport, and next year we’ll be back there again. Extrusion 2019 attracted nearly 500 people, who showed up to see the 75 exhibits, hear speakers and network with each other on Sept. 17 to 19. There weren’t any big lines running, like at NPE or the forthcoming K 2019, but most makers of extrusion equipment had booths and were available to talk. The morning speakers were at one end of the exhibit hall, so you could wander between exhibits and talks at will.

I was there for the whole two and one-half days, but I didn’t hear many talks. I wanted to see the exhibitors, and that, plus reconnecting with old acquaintances, didn’t leave much time. Many talks were available online to registrants, but that is deceptive. I haven’t looked at them much because of Griff’s Law, which has been up on my wall for the last 25 years: “Always Put Off Until Tomorrow What You Can Get Away with Putting Off Until Tomorrow!” Next to that sign, however, is another one that says: “If Not Now, When?”
I decided I could be of best use to PlasticsToday readers by listing who talked about what, so you can call or write the speakers and get the latest news or whatever they want you to know. As for my talk on “Inpush and Output”—how what goes in affects what comes out—you can have my 27 slides on request (see the end of this article for contact info) and ask questions later.

Almost forgot, but didn’t: There are no toxic plastics, none of them. And don’t you forget, either. Also, if you have ideas about why people are so receptive to anti-plastic images, please let me know.
Allan Griff is a veteran extrusion engineer, starting out in tech service for a major resin supplier, and working on his own now for many years as a consultant, expert witness in law cases and especially as an educator via webinars and seminars, both public and in-house. He wrote the first practical extrusion book back in the 1960s as well as the Plastics Extrusion Operating Manual, updated almost every year, and available in Spanish and French as well as English. Find out more on his website, www.griffex.com, or e-mail him at email@example.com.
Griff conducts live seminars across the country—the next ones are planned this winter in Southern California and Chicago. Seminars in your plant are also available. If you can’t attend his live events, he offers a Virtual Seminar, which can be seen any time, any where. E-mail Griff at the address listed above for more information.
