Customer Support - Screws & Barrels
Feedscrew Technology
Our ability to design and manufacture some of the industry’s most advanced and efficient feedscrews is one reason we have been an extrusion leader for more than 50 years. With our R&D facilities and team of experienced polymer process engineers, we offer customers world class screw design and technical capabilities.
R&D Capabilities
Our primary research and development center in Pawcatuck, Connecticut, USA, enables us to research, test, and supply custom feedscrew designs.
Quality Materials
Feedscrews manufactured from a variety of metals for corrosion and wear resistance.
Screws for Every Application
Screw sizes range from ˝ inch (13mm) to 12 inches (300mm) for single screw, and 40mm to 140mm for counter-rotating twin screw. Screws, including smooth and groove feed designs, can be customized for specific applications.
Proven Technology
Our DSB® and DSBM-T™ barrier screw technologies are known worldwide for consistently higher output rates, process stability, venting and devolatilization capabilities, distributive and dispersive mixing properties, and minimized polymer degradation.
Process Technology
Our experienced team of process engineers work with our customers on unique features.
Barrels
Our primary manufacturing facility in the United States and our D-S Brookes affiliate in England are unparalleled when it comes to bimetallic barrel production, service, and support. We build one piece barrels ranging in bore size from 1 to 20 inches (25 to 500mm) in diameter and up to 185 inches (4,700mm) long. Two piece barrels are available in lengths ranging from 185 to 295 inches (4,700 to 7,500mm).
Quality
Our alloys provide dramatically enhanced abrasion and corrosion resistance to barrels operating under severe conditions, especially those using filled materials including glass, titanium, dioxide, quartz, talc, mineral oxides and others.
Selection
We can manufacture virtually any barrel including vented, groove-feed, nitrided, jacketed, and re-sleeved.
Durability
New barrels for plastics and rubber applications are designed to last four to five times longer than equivalent nitrided products.
Quick Turn-Around
With knowledge of virtually every extruder brand in operation today, we have the expertise, people, and production facilities to supply you with barrels anywhere in the world.
