Vacuuminduction melting (VIM) is one of the most commonly used processes in secondary metallurgy applied for refining treatment in the liquid state and adjustment of chemical composition and temperature. To achieve the increasing quality demands on the resulting material and at the same time save raw materials such as alloying elements due to higher yield; and save energy, Vacuuminduction melting makes possible effective degassing of the melt and extra- ordinarily precise adjustment of alloy composition, since the temperature, vacuum, gas atmosphere, pressure and material transport (e.g., through stirring of the bath) can be adjusted independently of one another. Besides the exact concentration of alloying elements, the content of trace elements is also important for many alloys. Sampling the application of vacuumin the induction melting process is a must for many specialized materials. For example, vacuuminduction melting is indispensable in the manufacture of special alloys, which must be melted under vacuumor in an inert gas atmosphere because of their reactivity with atmospheric oxygen. The process is suitable for the production of high-purity metals within an oxygen-free atmosphere. This limits the formation of non-metallic oxide inclusions.

For more than 10 years, Sanket Power Systems have manufactured sintering furnaces for hard metals, cermets, magnets, MIM products and special oxide ceramics. The sintering process consolidates particles in a coherent, pre-determined solid structure. Mass transport in the atomic range happens during this process. Single-phase powders are sintered at 2/3 to 4/5 of their melting temperature, multi-phase powders (mixtures) are sintered near the solidus of the lowest melting phase.
