<p>[QUOTE=&quot;JPeace$, post: 2337019, member: 42727&quot;]Absolutely agree with the bolded sentence.&nbsp; I was trying to convey that in my message, but apparently, I didn&#039;t clarify it enough.&nbsp; I believe the pull away toning is impacted by this hardening as the highest stress point in the material is right around the &quot;details&quot; (stars, devices, date).&nbsp; Right at the junction of the fields and the devices/details.</p><p><br /></p><p>I did not comment on the dies, but what you posted certainly makes sense.&nbsp; When I worked for a motor lam stamper, we had 150+ high speed presses using primarily progressive dies to produce the lams.&nbsp; At the time I worked there, we purchased the dies, but the company had a long history of die manufacturing as well.&nbsp; We used carbon inserts on dies in which 3 million + lams were needed.&nbsp; I believe die life with carbon inserts was 300 million or so lams.&nbsp; Of course, there was die sharpening etc...&nbsp; I&#039;m only mildly familiar with the different grades of tool steel used when making the dies.&nbsp; I didn&#039;t really get into &quot;science&quot; behind the preparation of dies for production.[/QUOTE]</p><p><br /></p>
