The current trend is to reduce material costs by manufacturing foam core or mineral filled pipes, whilst still maintaining the technical requirements of the pipe such as barrier layers to reduce diffusion or pipes filled with fibre to reduce linear expansion.
Krauss Maffei has specifically designed multilayer pipe heads for each extrusion challenge.
"We can meet all of the needs of multilayer pipe producers involving up to seven layers with our pipe head line," Michael Hofhus, manager of pipe extrusion at Krauss Maffei, said.
"Our technology concepts for these complex systems can also result in savings in manufacturing costs and are flexible to meet market demands."
Customised co-extrusion solutions are designed for the manufacture of pipe with high filler content or foamed pipes. The systems can provide high quality product with significantly reduced weight of up to 25 per cent and real cost savings.
"We offer our customers an intelligent machine for manufacturing multi-layers pipe in the same footprint of a machine that manufactures single layer pipe," Hofhus said.
Direct extrusion systems can manufacture mineral filled pipes such as polypropylene filled with barium sulfate in a single stage procedure, eliminating downstream production processes which represents up to a 30 per cent cost saving. These particular pipes are used as wastewater pipes in large residential buildings as they noise dampen by up to 40 per cent compared to traditional pipe.
