Heat treatment refers to a metal thermal processing technology in which the material is in a solid state through heating, heat preservation and cooling to obtain the expected structure and performance. Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye. It will also enable our products to obtain better performance.

Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece, or changing the chemical composition of the surface of the workpiece , To give or improve the performance of the workpiece.
