WELCOME TO MY WEBSITE!

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 independent since 1961. I now do three things:

• Extrusion education (webinars and in-house training).
• Author and publisher of The Plastics Extrusion Operating Manual.
• Private consulting work, including legal assistance.
