They are an old and respected manufacturer of plastics and rubber screws, with old affiliations with personalities that I call "From the Golden Age of Plastics". Mike Mieduch, Sales Manager gave me a nice plant tour, and I actually saw something I have never seen before (which I will talk about below).
I also met with Jeff Kuhman, company founder and president of Glycon. Jeff goes back a long way, and he gave me a nice history of the company, and we talked about many mutual old friends, virtual pillars in the extrusion world, such as Imrich Klein, Chan Chung, Bob Barr, Chris Rauwendaal, and many others. Jeff and Glycon donated several extrusion screws of historical importance for the grand opening of the new Engineering building at UMASS-Lowell in November. He also wrote the history of extrusion for the Plastics Engineering Department to be read at the grand opening.
So... here are some of the basics. Glycon has been designing and manufacturing feed screws for 35 years at this location. Their specialty is custom high-performance screw designs which improve mixing while reducing overall melt temperatures at increase specific rates (kg/hr/RPM). Glycon had a long-term affiliation with Bob Barr where he would design and (at the time) Great Lakes Feedscrews would manufacture Barr's ET (Energy Transfer) screws.
Here is a schematic of how this design works:
In addition to manufacturing all types and sizes of screws for extrusion and injection molding, Glycon has its own patented Quick Shut-Off (QSO), non-return valve (US Patent Number 5,097,864) for injection molding. It's a really nifty design and a vast improvement over earlier ball or ring seal-type devices.
