Refining high-purity alloys by remelting them under vacuum.

Producing high-quality steel by remelting in a molten slag bath under vacuum.

Melting refractory metals like titanium and zirconium under vacuum.

Vacuum melting is a process where metals are melted inside a controlled vacuum environment to prevent reactions with oxygen, nitrogen, and other gases. Removing these gases helps protect from contamination and improves overall purity. The metal can also be refined as dissolved and chemically‑bonded impurities are removed, resulting in a cleaner, more homogeneous final material. This controlled melting environment is essential for producing high‑quality metals used in demanding applications.

Vacuum degassing removes dissolved gases, vapors, and moisture from liquids or paste by exposing them to lower pressure. Reducing the pressure makes these gases less soluble, allowing them to escape quickly and cleanly from the material. This controlled process helps prevent bubbles, reactions, and impurities that can affect product quality.

Vacuum brazing is a joining process where metal parts are bonded using a non‑ferrous filler metal that melts and flows between tightly fitted components. Performing this process in a vacuum removes gases and oxides from the brazing area, improving metal wetting and ensuring precise, contamination‑free, high‑integrity bonds.

Vacuum nitriding is a process that introduces nitrogen to the surface of a metal part inside a controlled vacuum chamber. As the part heats, the nitrogen reacts with the surface to form a thin, hardened layer that boosts wear resistance and protects against corrosion. This controlled approach strengthens the surface without altering the part’s shape, making it a reliable option for components that need long‑lasting performance.
