Tools used at major construction sites have to be tough. To make this new cover cap, designed to protect the high-quality components inside Hilti units against dust and dirt, the Bavarian specialists developed a TPE compound that satisfies this requirement to the greatest possible extent. This ring, two to three centimeters thick, bonds perfectly to the rigid polyamide component and, acting as a pliable "shock absorber between the cap and the machine itself, offers very good damping and resilience capacities, even at higher temperatures and in the presence of strong vibrations like those an impact drill will generate. Over and above that, the materials made by Kraiburg TPE also help ensure that Hilti tool users will have "a firm grip on their work. Making use of its exceptional bonding properties, TPE forms a protective layer for the rigid components making up the handles for rotary hammer drills and demolition hammers. The material offers safe and pleasant tactile properties. And when dealing with grip geometries that - since they are completely enclosed in TPE - do not require optimised bonding, Kraiburg TPE achieves convincing results with TPE compounds from the Thermolast K product group.
"Competent and solution-oriented collaboration with the TPE engineers together with extensive service at short response times quickly earned great favor among our staff, notes Ferdinand Kristen, who is responsible at Hilti for developing plastic casings for power tools. "The final aspect that convinced us, as a family operation, is that Kraiburg TPE puts its faith in high-quality products Made in Germany'. With this firm as a strategic partner we see great potential for further innovative product developments. Some are already in the pipeline. The companies are working together on new materials to be used close to the motor. In addition to withstanding temperatures of up to 140 °C, the materials offer additional advantages such as reduced product weight and greater resistance to aggressive media.
