I am an extrusion consultant and educator, and have been working with plastics extrusion since 1955 -- first as a technical service engineer with Union Carbide Plastics, and then independently since 1961.  I now do these things:

1. Live Full-Day Seminars, Introduction to Extrusion

  • no live seminars scheduled for the near future (virus) See Virtual Seminar below, available by email and OneDrive right now.

This is my basic introductory course that I've taught to over 5000 people since its first session back in 1979. The technical details change, but people still want to learn the practical basics.

For questions or to register, please call 301-758-7788 or email algriff@griffex.com

After virus danger subsides, this seminar is also available privately in 1- and 2-day formats -- please call or email for details.

2. The Virtual Seminar -- NOW!

  • Until now, if you wanted to attend my live Introduction to Extrusion seminar, you had to go to the host city on the day presented, or have it presented in-house. Now that's impossible until the virus rules are relaxed.
  • However, you can save the travel time and cost, and see it on your own schedule by having my 185-slide PowerPoint pack sent to you (with a Guide to the Slides).

For the single-attendee seminar charge of $US595 you receive the slide pack and guide right away.

You may see it at times of your own choosing, and share with colleagues in your own company and location.

You may still send me questions and comments (or even phone calls) afterward, which is the offer I make to all who attend my seminars in person.

For more information or to receive a Virtual Seminar, please call me at 301-758-7788 or email (algriff@griffex.com)

3. My Webinars

Since 2010 I have been presenting 1-hour free webinars from time to time. The most recent one was "What Every Extruder Should Know," presented May 14, 2019, and hosted by PlasticsToday. It was recorded and still available via www.plasticstoday.com. Call or email me for help if you have trouble registering.

  • Past webinars include:
  • "Throw Almost Nothing Away" -- the economic and technical aspects of recycling, in plant and out.

    "How to Read a Spec Sheet" -- information from resin suppliers is useful, but isn't always complete or consistent. This hour will help you get the most value from them.

    "The Ten (11) Key Principles of Extrusion" -- the basics of extrusion: mechanical, thermal, speed, plastic is the coolant, conveying in the feed zone, save all resin, power cost, the vital signs, output, shear-thinning, and the barrel-motor balance.

    "Plastics Chemistry for Non-Chemists" -- an easy-to-understand cartoon-based explanation of how monomers become polymers.

    "Plastics in the Environment" -- major issues (bag ban, phthalates, BPA, more) and reasons for the massive misunderstandings.

    "Testing Incoming Raw Materials" -- why you should be testing and how to do it.

    The slides for these past webinars are still available. To access them, or for questions on content, call me at 301-758-7788 or email to algriff@griffex.com.
