Vacuum Casting
What is it used for?
Vacuum furnace casting is a metal melting and casting process carried out in a vacuum environment.
The primary principle of vacuum furnace casting is the application of vacuum conditions to:
- Leading to stronger, cleaner and more reliable cast components with less defects.
- Facilitate degassing – Reducing internal flaws and effectively generates denser castings.
- Improve molten metal purity – Prevents contamination during melting and casting. The alloy elements remain more stable and controlled, maintaining the alloys properties and composition.
What materials are best suited for this process?
- Stainless steel – Vacuum conditions assist in reducing oxidation and control gas content such as oxygen and nitrogen.
- Titanium Alloys – Titanium is extremely reactive at high temperatures, so an inert atmosphere is essential to prevent contamination from oxygen, nitrogen and hydrogen.
- Nickel based superalloys – Vacuum casting improves alloy purity, reduces gas porosity and enhances fatigue performance.
