Barrel Sections
Ranging in diameters from 18mm to 180mm from 30+ OEM manufacturers, CPM Extrusion Group offers the industry’s widest selection of twin-screw barrel sections.
We have placed high priority on the development of advanced construction materials and the continuous improvement of our manufacturing process. Due to this and our emphasis on maintaining low costs and competitive lead times, there is no better source for your critical replacement barrel sections.
CLOSED BARREL
Commonly heated electrically and cooled with water through pulsed cooling
OPEN BARREL
Round or square opening on the top | Used for either feeding or venting
COMBI BARREL
Both top and side opening | Available alternatives are block type or with lateral opening only
ADAPTER PLATE
Used to support process section and for measurering purposes | Possibility to provide a port for injeciton valves in adapter plate openings
LONG DEGASSING BARREL
Used for degassing task with especially high volatile content
SOLID BARREL WITH PERMANENTLY JOINED WEAR PROTECTION COAT
Applicable through hot-isostatic pressing, flame spraying or other coating processes
BARREL HOUSING WITH EXCHANGEABLE THINLINER®
Thin-walled wear protection liners called Thinliner | Liner is exchangeable | Possibility of arranging cooling channels very close to process room
BARREL HOUSING WITH INLINER
Standard solution for high wear protection | Liner is exchangeable and can be manufactured from a large bandwidth of materials
BLOCK BARREL WITH TIE-ROD DESIGN
Various available designs, e.g. square flange barrels | Likewise braced with tie-rods or clamping flanges
ROUND, CLOSED BARREL WTH ROUND LINER
Removable liner | Can often be supplied with Thinliner® wear protection inserts
Barrel Components
In addition to our barrels, we offer and stock a wide range of barrel components which serve or add various functions. These include:
Top and side plugs to stop feeding or venting
Vent port adapters (types A, B, and C) to improve venting
Injection T-adapters to block adapter ports or accept injectors or measuring devices
Mounting hardware kits including water port adapters
Vent stacks (vacuum and atmospheric) for improved venting
