SEMS to Formed

This is a ball stud used in a lighting application with a Delta PT® thread. With our tooling and cold forming expertise EJOT ATF was able to design tooling that allowed us to manufacture the complete geometry of this part, minus threads, all on the cold forming machine. By doing so, we eliminated the SEMS washer operation, the cost of the washer and reduced the complexity of the part. With the cold formed collar in place of the SEMS washer, we also improved true position and perpendicularity for our customer in the application.
