In vacuum furnaces, inert gas technology, airflow, and air pressure form an integrated system to create optimal processing conditions. The vacuum environment eliminates oxidation, while inert gases like argon or nitrogen provide controlled atmospheres for specific treatments. Airflow ensures even temperature distribution and gas circulation, preventing hot spots. Air pressure management maintains vacuum integrity and controls gas density. Together, these elements enable precise thermal processing with minimal contamination, making vacuum furnaces essential for high-precision industries like aerospace and medical device manufacturing. The vacuum hot press machine represents another application of these principles for specialized forming processes.
