Now the summary of what you hear is recorded below for your reference. First, the mold design and structure 1. Die inspection process, we saw some typical progressive die. The row of continuous drawing mold, the workpiece diameter φ60 or so, 3 rows simultaneously stamping. Workpiece diameter φ20 or so, 6 rows simultaneously stamping. Progressive die with a bending process, an example is from the brass roll out of the forming contact holder, while the silver contacts (Chong
