With supersonic speed through existing boundaries - New possibilities through functional integration and multi-material

HERMLE offers a hybrid manufacturing approach called metal powder application (MPA) that combines additive and subtractive manufacturing. The cold gas spraying used in the additive process allows for the processing of metal powders without melting them.

HERMLE offers a hybrid manufacturing approach called metal powder application (MPA) that combines additive and subtractive manufacturing. The cold gas spraying used in the additive process allows for the processing of metal powders without melting them. The powder particles are accelerated to supersonic speed by the expansion of compressed and heated gas in a Laval nozzle. This kinetic energy is sufficient to form a metallic bond upon impact. The temperatures used in the MPA process are significantly lower than the melting point of the starting materials. This allows for the processing of crack-sensitive materials and integration of active components into parts. The MPA process can produce complex components with active elements like heating or thermocouples, opening up new possibilities for functional integration. It can also create multi-material components with sharp or graded material transitions, which combine and apply opposing material properties locally and specifically. The lecture will present successful application examples in addition to a detailed explanation of the MPA process, including the application mechanism, machine concept, and material portfolio. The application examples will focus on the potential benefits of integrated functional elements and the new possibilities offered by multi-material components.
