Munich -- For more than 45 years, KraussMaffei says, it has been active in equipment for processing polyurethane, building premium quality machines and systems for this purpose.
Development of processing machines for PU at KraussMaffe began in 1967. "KraussMaffei is a forerunner for using this material in plastics production. Thanks to years of experience, an up-to-date, premium-quality machine portfolio and a large store of technology and procedure expertise, we've developed into a worldwide market leader," said Nicolas Beyl, appointed as head of the Reaction Process Machinery Division in February 2012.
KraussMaffei focused on high-pressure processing of PU from the beginning. New fields of application, machines and methods are being developed constantly to this day, in close cooperation with raw material manufacturers and processors.
"We want to strengthen our activity in the area of reaction process machinery globally and to demonstrate additional application and efficiency potential for our customers along their entire value chain. In particular, we want to draw them to us using combinations of machines and methods for injection moulding and reaction process machinery and by using new technologies," Beyl added.
These strengths recently received positive feedback at the recent US NPE 2012 trade show in Orlando, Florida, where KraussMaffei showed manufacture of an armrest using the SkinForm process was shown. In one machine/the injection-moulded carrier was flow-coated with a foamed aliphatic polyurethane with pleasant surface characteristics and outstanding UV resistance.
"KraussMaffei's extensive Technology3 expertise across the entire process chain was apparent at this machine. The machines, automation, mould technology, and custom solutions were all from our company and unified our expertise," said Beyl.
The group wants to advance innovative solutions in growth fields, including lightweight construction and fibre-composite technology. "In recent years we have been able to win numerous orders in these areas worldwide. We also have a worldwide one-of-a-kind expertise center in this area, the fibre composite technology TechCenter we opened in Munich in 2011," said Beyl.
KraussMaffei participated in a project with 12 other companies which won a JEC Europe Innovation Award this year. A development consortium headed by the Fraunhofer ICT was developed the SCS process (structural component spraying) for lightweight structures based on sandwich structures and spray processes for glass-fibre reinforced polyurethane resins.
In addition to KraussMaffei, partners Bombardier, Fraunhofer ICT, Bayer MaterialScience DEC, the DLR Institute of Vehicle Concepts, the University of Stuttgart (IFB) and the Institute for Technology in Karlsruhe (wbk) were responsible for the manufacturing process for a protective cover for a train's diesel engine, making extensive developments along the value chain.
Sandwich core materials, cover layer materials, manufacturing processes, fire protection systems, design principles and calculation methods were developed for this sandwich structure component 4.5 m long by 2.5 m wide.
The innovative design with identical interfaces using glass-fibre reinforced PU sandwich structures makes it possible to reduce the weight of the safety enclosure while simultaneously reducing the number of components.
