After forming the workpiece, in order to ensure its quality and reliability, will conduct the heat treatment process. But there are many factors that will affect the effect of the heat treatment process, so you want to control and regulation, mainly related to the following factors.

On the one hand the impact of personnel, which makes highlights; followed by heat treatment of tooling, as more types of tooling, and sometimes use some measuring instruments, thus requiring the operator to strictly observe the rules of measuring equipment and tooling, right reasonable for maintenance. And also required to do a good job of measuring instruments calibration, maintenance and identification, and so on.
In addition, the influence of the workpiece material itself can not be ignored, since the heat treatment process of material processed, transport, mixing may occur after the inventory, wrong material, loss, corrosion, bump and deformation phenomena. So, this should also be particularly important. The last remaining heat treatment process specifications, we must first have a proper heat treatment process, but also have a more complete job specifications, so as to control the quality of the heat treatment.
