Twin barrels

Perfect for high-performance extrusion.

With a combination of different bimetal alloys, we apply our wear protection exactly where it is needed in your production process: heavy-duty wear protection for the high-load areas of the barrel, more affordable wear protection for less heavily used areas. A tight fit between the bimetal sleeve and the outer body improves the temperature control of the twin barrel.


Profitableness
Cost-effective regeneration of the wear protection

Different wear protection layers wear down at different rates. Our modular system allows you to exchange only the worn area of the barrel instead of the entire bimetal sleeve. We offer you this service for all common barrel builds.
