World-leading plastics machinery specialist, Krauss Maffei Extrusion of Munich, Germany offers customised solutions for plastic pipe manufacturers to produce complex plastic pipes with various functional layers.
The current trend is to reduce material costs by manufacturing foam core or mineral filled pipes, while 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’s pipe head line can manufacture specifically designed multilayer pipe heads for each extrusion challenge. According to Michael Hofhus, Manager of Pipe Extrusion at Krauss Maffei, the pipe head line can meet all the needs of multilayer pipe producers involving up to seven layers, resulting in savings in manufacturing costs.
Customised co-extrusion solutions are designed for the manufacture of pipes with high filler content or foamed pipes. The systems can provide high quality product with significantly reduced weight of up to 25% and real cost savings. The Krauss Maffei machine for manufacturing multi-layered pipes has the same footprint of the machine that manufactures single layer pipes.
Direct extrusion systems can manufacture mineral filled pipes such as polypropylene filled with barium sulphate in a single stage procedure, eliminating downstream production processes and saving up to 30% in cost. These pipes are used as wastewater pipes in large residential buildings as they dampen noise by up to 40% compared to traditional pipes.
