Vacuum Quenching Machine

Vacuum Tube-Type Quenching Machine is a heat-treatment device designed to increase the hardness of metal materials through a rapid cooling process carried out inside a low-pressure (vacuum) chamber. The machine features a cylindrical tube capable of achieving a high vacuum level, effectively minimizing oxidation, deformation, and contamination during heat treatment.

The process begins by heating the metal to its austenitizing temperature, followed by rapid cooling using a quenching medium such as pressurized inert gas, oil, or specialized quench fluids circulated in a controlled manner within the vacuum tube. The oxygen-free environment ensures stable and precise quenching, resulting in improved hardness and a more uniform microstructure.
