Krauss-Maffei Berstorff (U.S. office Florence, Ken.) has redesigned its ModulPlus line of twin-screw extruders to shorten delivery-lead times and reduce cost. On the new configuration, metering, materials handling, pelletizing and control modules are still completely assembled at the company’s plant in Hannover, Germany. But now the extruder is no longer integrated into a steel module. This offers free access to the extruder at ground level and is said to save up to 20% in steel structure expenses are reduce manufacturing time by about two months. It also permits, for example, assembly, completion and testing of the steel structure and peripheral components to be conducted in the USA, with this equipment subsequently combined with an extruder manufactured in Germany.
The machine builder says more than 100 ModulPlus lines are operating around the world. The system is composed of fully-wired and piped individual units that are mounted and tested in Hannover. Upon customer request, wet commissioning and customer personnel training can also be performed in Hannover. At the place of destination, the modules are then simply set up, connected and started. This arrangement offers compounders the benefits of quick start-up without any interface problems, easy disassembly and re-installation in the case of production relocations, and low total investment cost, as a simple production area is usually sufficient and does not require sophisticated steel structures.
