It is necessary to adopt a flip-chip suspension in the mold. In the past, such workpieces often used flip drills.

To this end, we have designed two kinds of fixtures that can press the workpiece from the bottom to the top according to the specific shape of the workpiece and the positioning requirements of the workpiece.
