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.

2. GLYCON CORP.
GLYCON IS AN INTERNATIONAL SUPPLIER OF MELT
STREAM COMPONENTS AND SERVICES FOR THE
PLASTICS PROCESSING INDUSTRY

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.

7. DM2™ FEEDSCREW
THE DM2™ SCREW FROM GLYCON CORP. HAS BECOME RECOGNIZED
AS THE MOST VERSITILE AND UNIFORMLY SUCCESSFUL HIGH-PERFORMANCE
SCREW DESIGN EVER INTRODUCED
PROCESS ADVANTAGES INCLUDE:
•EXCELLENT LOW SHEAR MIX OR DISPERSION.
•LOWER MELT TEMPERATURES.
•OUTSTANDING TEMPERATURE UNIFORMITY.
•HIGHER RATES IN TERMS OF POUNDS PER HOUR PER SCREW REVOLUTION.
•ELIMINATION OF SHEAR SPLAY.
•RETENTION OF DESIRABLE PHYSICAL PROPERTIES SOMETIMES LOST DUE TO THERMAL
DEGRADATION WITH HIGHER SHEAR SCREWS.
•WIDER PROCESSING WINDOWS ON ALL MATERIALS.

8. HURRICANE FEEDSCREW
HURRICANE™ ADVANTAGES:
• PERFECT FOR PROCESSES THAT REQUIRE VERY AGGRESSIVE MIXING.
• INTRODUCES CHAOTIC MIXING TO THE MATERIAL.
• BETTER MIXING TRANSLATES TO BETTER PRODUCT UNIFORMITY AND LESS SCRAP.
• DESIGN IS SELF CLEANING REQUIRING REDUCED PURGE TIME BETWEEN MATERIAL OR
COLOR CHANGES.
• MULTIPLE REVERSE FLOW GROOVES ENSURE COMPLETE MIXING

9. GLYCON QSO VALVE
GLYCON’S QUICK SHUT-OFF VALVE (QSO®) OFFERS CONSISTENT
INJECTION MOLDING RESULTS WITHOUT SHORT SHOTS OR SPLAY
DEFECTS THAT CAN BE CAUSED BY SOME SCREW TIPS. THE QSO®
COMBINES MANY OF THE ADVANTAGES OF MANY OTHER TYPES OF
SHUT OFF VALVES INTO A TIP THAT CAN VIRTUALLY ELIMINATE
VALVE RELATED SCRAP
•QSO®’S SMOOTH FLOW PROFILE PROVIDES HIGH FLOW RATESWHILE MINIMIIZING
STRESS AND SHEAR.
• QSO®’s SHOT TO SHOT CONSISTENCY RESULTS IN EXCEPTIONALL LOW PART WEIGHT
VARIENCE.
• QSO®’s ONLY MOVING PART IS THE POPPET THAT IS MANUFACTURED FOR LONG LIFE
AND DURABILITY.
