Vacuum Annealing Furnace

Annealing is a critical metal heat treatment process that involves slowly heating the metal to a specific temperature, maintaining it for a designated period, and then cooling it at a controlled rate. This process aims to:

Reduce hardness, improving machinability and cutting performance
Relieve residual stress, stabilizing dimensions and minimizing the risk of deformation and cracking
Refine Grain Structure: enhancing material uniformity and eliminating structural defects

Our vacuum annealing furnace is designed for precise annealing processes under vacuum or inert gas protection, ensuring high-quality surface finishes and enhanced material properties.

Process Control

The vacuum annealing furnace operates under vacuum or inert gas protection, effectively preventing surface oxidation and rusting during the annealing process. This ensures higher processing quality, consistent material properties, and long-lasting durability for treated components.
