Radio waves power Kurtz foam molding machine

Wave Foamer This automatic machine for particle foam molding from Kurtz GmbH can create EPS insulation panels, packaging and automotive components such as seat and bumper parts. It can process materials at temperatures of up to 482 degrees Fahrenheit, making it appropriate for use with high-temperature engineering resins; it also can mold components with as much as 70 percent recycled content.

What’s new? The machine, and its electromagnetic wave technology. Traditional particle foam molding machines use steam to expand and fuse polymer beads. The Wave Foamer uses radio waves that cause polar molecule chains to oscillate, generating friction and heating the beads. At K 2019, Kurtz showed a Wave Foamer molding EPS. The company is working with resin manufacturers to develop more materials compatible with the process, including expandable PP and biodegradable resins such as polylactic acid.

Benefits Energy efficiency. The Wave Foamer uses as little as 10 percent of the energy required by the traditional steam process for creating expanded foam. It also eliminates the need for complex steam installations, water-treatment equipment and cooling water installations.
