Bayer and Krauss-Maffei help Camoplast develop a polyurethane-based long fiber system for large molded parts
Doug Smock reports in Design News on a new technology developed jointly between Camoplast, Bayer MaterialScience and Krauss-Maffei. Long glass fibers and polyurethane resin are injected in a single step process. A fiberglass chopper is attached to the polyurethane-dispensing mixhead connected to a robot. The robot then moves over the open mold simultaneously dispensing both the long glass fibers and the polyurethane resin as an open-pour. Then the mold is closed to form the final part in a low-pressure process.
The objective is to achieve a superior Class A finish and reduce part weight without sacrificing strength.
