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.
