Coextrusion line Reifenhäuser

This extrusion line consists of a co-rotating twin-screw-extruder and two single-screw-extruders, coupled over a coextrusion block. It was supported in the context of a research project to produce a thermoplastic circuit board and was procured by the Federal Ministry for Education and Research. The main application area is for this reason the coextrusion of a three-layer substrate material for conventional circuit boards, who have a core of foamed and a top layer of compact high-temperature thermoplastics. Of course, with this system configuration the processing of conventional technical thermoplastics is also possible.
