Detection of Remaining Runner

Remaining runner may cause defects in coating in post-processing. Remaining runner is determined after runners are cut by robots. There are cases where cutters do not cut properly due to variations in the positions of the runner after removal from the bumper mold. Until now, visual checks were possible when workers reloaded the stocker, but as reloading work is now automated, it has become necessary to have an inspection mechanism to replace visual checks.
