Stuttgart, Germany — KraussMaffei plans to present polyurethane composites machinery at this year's Composites Europe event here in September.
KM presents PU composites machinery
Erich Fries: ready for large series production
A highlight of the stand will be its iPul system. This, the firm said, encapsulates the resin infiltration of the fibres, which traditionally takes place in open vessels, in an injection box. Enclosing resin infiltration allows the use of fast-reacting systems such as polyurethane and increases production speed from the usual 0.5 to 1.5 m/min to approximately 3 m/min, the company said.
In addition, the company will be showing its C-RTM pressure process, where C stands for compression. The addition of resin, usually polyurethane, is carried out in a slightly open mould, fibre content of significantly over 50% is possible in the process, KM added. Surface RTM where parts with a paintable polyurethane-rich surface will also be on display, Krauss Maffei said.
"The market for composite continues to develop very dynamically. Important drivers of innovation are automated processes that allow manufacturing that is ready for large series production, said Erich Fries, head of the composites/surfaces business unit of KraussMaffei.
