Vacuum Heat Treament Systems

The core competency of PVA TePla is to build systems for vacuum and pressure sintering of hard metals. The COD plants designed for this purpose are also supremely suitable for sintering ceramics, a material that is being used in increasing measure in car and engine production due to its low specific weight. Tools with outstanding material properties such as abrasion resistance and therefore tool life are manufactured in the thermal sintering processes under vacuum conditions and the subsequent hot isostatic processes under gas pressures of up to 100 bar. The high temperature regularity of the PVA TePla systems ensures that the products are all of a high quality.

One key industrial process, namely the melting and casting of metals, generates considerable benefits for the quality and precision of end products when performed under vacuum conditions. The process involves the melting and cleaning of precious metals, the alloying of special materials in graphite and ceramic crucibles, and the casting of blocks and moulded parts free of holes and pores. Vacuum melting and casting facilities are used, for example, to purify gold and platinum by melting, as well as for moulded items such as machine parts, turbine blades, medical implants such as hip joints, and heart valves. Vacuum processes performed under high temperatures ensure that no oxidation occurs and that the workpieces remain free of pores. This, in turn, means uniformly pure materials with very low variation in physical parameters.
