Heat treatment

Metal heat treatment is one of the important processes in mechanical manufacturing. It does not change the shape of the workpiece and the overall chemical composition. By changing the surface or internal structure of the metal material, the required mechanical, physical and chemical properties are obtained, thus improving the service life and quality of the parts.

Jingcheng company has its own heat treatment workshop and rich process experience, can be annealing, tempering, quenching and other heat treatment process.Our one-stop production service system can effectively shorten the production cycle of products, and provide stable quality bulk products.Thus saving the customer cost.
