Glycon Corp. is an innovator in the design and manufacturing of feed screws, barrels, non-return valves and other melt stream solutions for injection molding, extrusion and blowmolding.

For more than 30 years, Glycon Corp. has focused on helping our customers to become better, more efficient processors. Our current family of advanced technologies are all designed specifically to improve throughput, increase quality, reduce scrap and streamline processing. Whether your application is simple or complex, we can help improve your machine efficiency, part quality and reliability.

Product & Process Development

As processors gear up for production on a new project, Glycon's dedicated Product Development Center has the resources to help optimize screw performance, testing several different designs and then zeroing in on the best melting and mixing combination. Or, if a molder is having a problem with splay or burning, or if an extruder is not getting proper mixing or sufficient throughput, technicians at the Center, can reproduce these problems under controlled conditions and quickly find ways to attack the problem through the application of the latest screw and processing technology.

Rebuilding Services

Glycon Corp. experts can help extend the life of costly meltstream components. Feedscrews can be rebuilt to match original performance specifications. Barrels can be resleeved to original dimensions. Other components, like our QSO® non-return valve, can be rebuilt. All done quickly and with the highest standard of quality.

Preventive Maintenance & Installation

Glycon Corp. can assist with setup and maintenance of your feedscrew and related meltstream components. Our 10-Step Field Service Program streamlines setup and checks that your feedscrews are operating correctly. We can also design a maintenance program to reduce downtime and keep your systems operating as efficiently as the day they were installed. And we can train your maintenance personnel or implement the program ourselves.

Distributive Mixing & Melting Screw
Barrier Screws
Feedscrew Rebuilding
General Purpose Feed Screws
Glycon Barrels
QSO Non-Return Valves

  1. 1. GLYCON
  2. 2. GLYCON CORP. GLYCON IS AN INTERNATIONAL SUPPLIER OF MELT STREAM COMPONENTS AND SERVICES FOR THE PLASTICS PROCESSING INDUSTRY
  3. 3. Celebrating over 30 years in business, Glycon is an innovator in the design and manufacturing of screws, barrels, shut-off valves and other meltstream solutions for injection molding, extrusion and blowmolding. With a unique combination of standard products and custom engineering capabilities, Glycon helps plastics processors increase material throughput, shorten cycle time, improve mixing of color and additives, and generally enhance product quality and plant productivity. Jeffrey A. Kuhman founded the company in 1976 and he continues as President and CEO today. Glycon originally operated under the name Great Lakes Feedscrews but changed to its present name when the business expanded to include the full range of meltstream products, backed by a wide array of technical resources, including advanced R&D, process problem solving, training and field service. Today, Glycon meltstream solutions are at work around the world, increasing productivity and quality for companies like Plastech Engineered Products, Newell/Rubbermaid, Saturn, Dow Chemical and Lear Corporation; and advancing the frontier of processing technology in cooperation with machine builders like Milacron, Ube, Krauss Maffei, Bekum and Graham Machinery.
  4. 4. GLYCON FACILITIES DEDICATED R&D CENTER GLYCON OPERATES A DEDICATED R&D CENTER FOR ADVANCED DEVELOPMENT PROJECTS. THIS CENTER INCLUDES BOTH EXTRUSION AND INJECTION SYSTEMS WHICH ALLOW US TO OPTIMIZE A MELTSTREAM SOLUTION FOR YOUR RESIN AND PROCESS, WITHOUT INTERRUPTING YOUR PRODUCTION STATE OF THE ART MANUFACTURING COMPEX SITUATED ON 5 ACRES AND INCLUDING OVER 14,000 SQUARE FEET OF MANUFACTURING SPACE GLYCON IS SITUATED TO GROW WITH YOUR COMPANY.
