After extensive construction work in its innovation center, the LEHVOSS Group has put another compounding plant into operation at its Hamburg location. The twin-screw extruder used was tailored to the requirements by the manufacturer KraussMaffei Extrusion GmbH. For the development of innovative plastic compounds, recyclates, concentrates, additives and hotmelts, the high-temperature plant is equipped with various side extruders and dosing. A wide range of raw materials such as granulates, fibers, flakes, powder and liquids can be metered. Newly developed screws with a special design for an adapted and optimized melt preparation are also used. This makes it possible to produce, among other things, highly filled, for example highly conductive, plastics.
