In order to make metal workpieces have the required mechanical properties, physical properties and chemical properties, besides reasonable selection of materials and various forming processes, heat treatment processes are often essential. Heat treatment generally does not change the shape and overall chemical composition of the workpiece, but imparts or improves the performance of the workpiece by changing the microstructure inside the workpiece or changing the chemical composition on the surface of the workpiece. Its characteristic is to improve the internal quality of the workpiece, and its function is to improve the mechanical properties of the material, eliminate residual stress and improve the machinability of the metal.

Sintering refers to the transformation of powdery materials into dense bodies, which is a traditional process.

The baking paint treatment can give metal various colors and different textures. It is painted on the metal surface as a surface treatment, which has both protective and aesthetic functions.

From traditional machinery manufacturing, to the production of high-tech semiconductors, electric vehicles, and drones, nearly all key components require heat treatment.

Low-temperature treatment is a sub-zero process, which is carried out immediately after quenching and is carried out by continuous tempering. The ultra-cold treatment has a significant improvement in the wear strength of the workpiece and has a breakthrough benefit for the stability of the mold size.

Quenching is a heat treatment process for metals and glass. Heating alloy products or glass to a certain temperature, then rapidly cooling in water, oil, or air containing minerals, generally used to increase the hardness and strength of the alloy.
