Abstract：A powder metallurgy process preparation scheme for the cam head lock of a chef's machine was devel‐
oped and studied. By studying the original design and understanding customer requirements, the structure of the
cam head lock forging parts is complex, and it is difficult to ensure the accuracy of key part dimensions, contours,
and positions. The low qualification rate of mass production leads to a decrease in quality and an increase in cost.
The new scheme utilizes the characteristics of powder metallurgy technology. After the mold is pressed and
formed, post-treatment processes such as sintering hardening and tempering are used to ensure size, contour, and
part strength. The results show that the quality and efficiency of the parts prepared by the new process scheme have
been greatly improved. The subsequent production practice has also verified the economy and practicality of the
powder metallurgy process.
