Industrial Microwave – HEPHAISTOS

The newly developed VHM HEPHAISTOS Industrial Microwave Oven is an internationally patented system and characterized by a very high field homogeneity. For the first time, the advantages of microwave technology have been developed successfully to an industrially mature high technology.

The high field homogeneity allows for the manufacture of high-quality CFC aircraft structures, for instance. Conventional production systems (e. g. metal tools) may be kept. The fibre composites are of a high lightweight construction potential and, hence, comply with the strict cost and weight requirements of aircraft industry. The advantages of the HEPHAISTOS system may also be used in other applications, for instance in the automobile industry. Microwaves are the only physical heating method for the specific, volumetric heating of a product. The furnace chamber itself remains cold.

Advantages Reduced production costs Shorter heating, process, and cooling times compared to conventional methods, as a result of which energy is saved. The products only are heated by the microwave. The furnace chamber itself is not heated and does not have to be cooled down. Use of metal parts, e. g. conventional metal tools and feeding systems, in the microwave field (no transparent materials are required, but can be applied of course).

Specific, volumetric heating of products Microwaves penetrate into the material directly and heat the product. As a result, heating rates and throughput can be increased considerably.

High product quality by sufficient homogeneity of the microwave fields Thanks to the use of thermoelectric foils additional positive effects and material characteristics are achieved.

Modular design The systems designed extend from the laboratory up to the large scale that is needed in the aviation industry for example. For heat treatment of material used by the aerospace & defence industries, Vötsch Industrietechnik offers the appropriate ovens which fulfil the requirements of the standard AMS 2750 D.
