FAQ
The core difference lies in the working environment. Our equipment operates under a high vacuum (e.g., -0.1 MPa) and inert gas protection, which completely prevents material oxidation, resulting in castings with a mirror-like finish and high purity that are free of internal defects. This is unachievable with standard induction furnaces that operate in an atmospheric environment.
Yes. FOCO Induction offers flexible customization. Our vacuum pressure casting machines cover capacities from 1 kg to 3 kg (Au), and our vacuum ingot casting machines handle 1 kg to 30 kg ingots. Power can also be matched to your production needs, ranging from 8 KW to 80 KW.
The equipment is designed to use high-purity Argon or Nitrogen as the protective gas. Our equipment comes with a fully integrated gas path and control valves; it is ready to use once connected to the gas source.
The equipment comes standard with a water cooling system. We offer various cooling solutions: you can choose to connect to a tap water supply (if flow rate and pressure requirements are met), or opt for an independent water chiller for optimal results and energy efficiency.
