Abstract
A system and method for manufacturing a top mount for a vehicle suspension includes loading a top mount body, a journal, and a plurality of knurled studs into a lower die assembly. The lower die assembly includes a stationary die base, a floating die top, and a pusher shaft. A pusher head assembly applies a downward pressure to insert the knurled studs into the top mount body, while the pusher shaft substantially simultaneously applies an upward pressure to insert the journal into the top mount body. The floating die top and the pusher head assembly are raised in tandem to eject the top mount from the stationary die base. The floating die top and the pusher head assembly then retract so that the top mount can be removed from the system.
