GLYCON

GLYCON CORP.

GLYCON IS AN INTERNATIONAL SUPPLIER OF MELT STREAM COMPONENTS AND SERVICES FOR THE

PLASTICS PROCESSING INDUSTRY

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.

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.

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

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.
