What is the surface treatment technology of mold accessories?

In the mold industry, for the mold parts used, in addition to requiring high enough strength and toughness, its surface properties also play a crucial role in the working performance and service life of the mold parts. The improvement of these performance, relying solely on the improvement and improvement of the substrate is very limited and uneconomical. Therefore, surface treatment technology is needed. So do you know what the surface treatment technology of mold accessories is?

Mold parts surface treatment technology:

Mold accessories surface treatment technology is a systematic engineering, through the surface coating, surface modification or composite treatment of mold accessories, change the surface morphology, chemical composition, organizational structure and stress state of mold accessories, to obtain the required surface properties.

From the way of surface treatment, it can be divided into: chemical method, physical method, physical chemical method and mechanical method. Although new treatment technologies aimed at improving the surface properties of molds continue to emerge, the main applications in mold manufacturing are nitriding, carburizing and hardening film deposition.

In addition to the reasonable coordination of the matrix with high enough strength and toughness, the surface properties of the mold accessories are crucial to the working performance and service life of the mold. These surface properties refer to: wear resistance, corrosion resistance, friction coefficient, fatigue performance, etc. The improvement of these properties, relying solely on the improvement and improvement of the base material is very limited and uneconomical, and through surface treatment technology, you can often receive twice the result with half the effort, which is also the reason for the rapid development of surface treatment technology.

In summary, it is the surface treatment technology of mold accessories. Although new treatment technologies have been continuously improving the surface properties of mold parts, in the manufacturing process of mold parts, nitriding, carburizing and hardening film deposition are widely used.
