A lot of internal engine components, mostly ball plungers for valve lifters for VW, Audi, Mercedes, GM, Chrysler, Ferrari, and we just picked up a line for Cummins. We also produce one line of varviable valve lifters for new GM products as well as pump actuator roller bearings.
The largest coldformer we have here is a National, the dies for forming the rollers are about 80lbs each and runs 5 stations. For comparison the smaller coldformer dies weigh about 5lbs.
I'll post a pic of part progressions here shortly. The machines basically take a small coin of steel, jam a punch into the steel which jams into the die and makes all the formations by pressure alone. The national is a loud mother fucker when it's running.
Valve lifter line is a lot of milling hardened steel, turning, grinding with abrasive wheels, small tolerance honing, special form milling, as well as front/back chamfering on multiple through holes.
