Jerry, I knew exactly what you meant about cold forming, I recently toured a plant where I was applying for a job. They hot form automotive valves from steel wire. It was very interesting to see all the machinery from the '80s or earlier they had. What really got me was the thread rolling machines they were using to straighten out the valve stems after forming the tulip end, I had never considered a thread roller could be used for that.

We had a sizeable thread rolling dept. What was unique, is the process used to make the threading dies. A crush grinder, resembling a large surface grinder, formed the dies. We did no hot forming, so I have little knowledge of that process..We did have huge heat treating depts., which assisted in keeping the entire factory hot in the summer..phew.!!:):) I worked for Townsend/Textron near Pittsburgh, Pa..Textron had many divisions nation wide..
