Extruder and Injection Barrels

At R. Dray Mfg. we have decades of barrel design experience for both injection molding and extrusion applications. Although the feedscrew is the prime mover in any molding operation, the barrel quality and treatment should not be overlooked. Proper barrel design and care ensures a successful project. Barrel strength, heat transfer, quality, and wear-life greatly impact the feasibility of every project. We can accommodate a complete selection of replacement barrel sizes with a wide range of bimetallic inlays to ensure the proper barrel for your molding and extrusion operation, as well as emergency barrel repair.


Vented Extruder Barrels

Our team of engineers can design and manufacture new vented barrels and feedscrews to maximize your production efficiency. It is important to optimize vented barrels and feedscrew designs to improve overall extrusion performance. 


Injection Barrel and Extrusion Barrel Repair

New barrels can be expensive and lead times can be difficult. In many cases we are able to save you time and money by re-sleeving existing barrels to like new condition. Worn barrels can be re-sleeved with new or improved bimetallic liners to get you back up and running, fast! We also offer expert feedscrew rebuilding services to save you time and money.
