For the first time, wet molding is fully automated
Live demonstration at the Competence Forum

The new, fully automated wet molding system from KraussMaffei Reaction Process Machinery will be premiered at the Competence Forum on June 6 and 7 in Munich, which allows the cycle time to be cut in half and increases process reliability compared to manual solutions. Visitors to the TechCenter will get the chance to see a live demonstration of polyurethane-based sheet component manufacturing on the turnkey system.

In the wet molding process, a matrix material is applied in continuous strips to a flat-lying semi-finished fiber product and then pressed into shape in a mold. Advantages over the established high-pressure process include a shorter cycle time because wetting takes place outside of the mold, the obsolescence of preforming and the option of using recycled fibers. A fully automated system will demonstrate the technology using a test plate made of basalt fibers. A robot equipped with needle grippers picks up the fiber mats and feeds them to the application table, where a handling robot applies the polyurethane matrix using a mixing head (MK 10-2K-RTM) and flat sheet die. The gripping robot places the mats into the mold where the molding and curing process begins. The implemented MX mold carrier with a clamping force of 8,000 kN has three interfaces, with the option to process epoxy, polyurethane or polyamide. A RimStar 8/4 RTM metering machine with polyurethane matrix is also used.
