Upscale extrusion line application-specific
MUNICH — KraussMaffei Berstorff has developed a high-end extrusion line for making sealing profiles for the automotive industry and makers of other technical profiles.
The line is designed to run polypropylene and thermoplastic elastomers.
Because of its modular design, the machine can be tailored to specific uses, from conventional mono-extrusion to hybrid profile production lines with a flock-tape system or steel inserts.
KraussMaffei Berstorff is based in Munich. Its U.S. operation, KraussMaffei Corp., is in Florence, Ky.
